Novas Características de Gerenciamento Exchange System Manager Move Mailbox mais configurável Mailbox Recovery Center melhorado Log de Erros melhorado Melhor gerenciamneto de Public Folders DNS Resolver Tool Listas de Distribuição dinâmicas Suporte a Volume Shadow Copy Exchange 2003 features new tools that reduce clicks and make administration easier, such as the Exchange System Manager. In earlier versions of Exchange, you had to move log files yourself with directory modification tools and with the information gained from studying Microsoft Knowledge Base articles. In Exchange 2003, message tracking log files, as well as X.400 message transfer agent (MTA) queue data and Simple Mail Transfer Protocol (SMTP) queue data, are moved by using Exchange System Manager. Other Exchange System Manager improvements include: A user interface that offers simplified search filter, improved sorting by columns, and the ability to select multiple queues and messages for manipulation. Queues that are centralized on a per-server basis as opposed to a per-virtual server basis, which means all queues on a server can be viewed in one location. Increased performance in queue enumeration, and all queues are initially displayed in Exchange System Manager. Control of Exchange System Manager is returned to you before all queues are displayed. Exposure of all system queues, which helps you troubleshoot. Exchange System Manager includes the Enable Forms-Based Authentication feature on the virtual servers so authentication cookies can be enabled or disabled easily through the UI. More exposed cluster action. In a cluster, status can be viewed for virtual servers and failover. The addition of Windows Management Instrumentation (WMI) classes as well as many other new features. The Move Mailbox tool helps ease mailbox movement from one server to another or to a different Exchange store by selecting multiple mailboxes. With the Mailbox Recovery Center, you can scan the mailbox database and determine all disconnected mailboxes; automatically match user mailboxes to user accounts in Active Directory; recover individual or multiple mailboxes; and identify conflicting accounts. You can enable automatic error reporting to Microsoft. Improvements have been made in the UI for managing public folders including several new tabs for management. In addition, you no longer have to load a separate client to view public folder contents; contents can be viewed through the System Manager. You'll see this in the demo. Enhanced DNS-based Internet mail delivery. Get load balancing, better performance characteristics, and better tolerance of problems associated with network or host unavailability and external Domain Name System (DNS) server responsiveness. Reduce the time you spend managing distribution lists with the new query-based distribution groups. These groups achieve the same functionality as standard distribution lists, but instead of specifying static user memberships, they allow the use of an LDAP query to specify the members of the distribution lists, essentially creating self-updating distribution lists. You'll see this in the demo. Exchange 2003 supports the Volume Shadow Copy service implemented in Windows Server 2003. The copy service functionality gives you a quick backup-and-restore because a mirrored copy of the database exists at any time and can be used for restore processes.

Exchange Server 2003 e Microsoft Office Outlook 2003
Classificação de mensagens Data, assunto, conversação, tamanho ... Remoção de características confusas e desnecessárias da visão default Fácil acesso a mensagens importantes Interface intuitiva e fácil para usuários novos Acesso rápido a informação Trabalho Off-line Outlook 2003 has been designed with a focus on the primary uses of Outlook, reading and responding to messages. You can save time and find messages faster by grouping messages by date, size, conversation, subject, importance, or other criteria. Many confusing or unnecessary features have been removed from the default Outlook view, such as File System Browsing, Address Bar, and IE Favorites from within Outlook. This allows users to concentrate on the triaging, reading, and responding to . Find important messages or messages you need to respond to easily by saving the results of commonly used searches as Search Folders instead of having to re-run common searches each time you need them. Search Folders provide an automated way to keep relevant s together without moving them to other folders. Search Folders require a connection to Microsoft Exchange Server You'll see Search Folders in the upcoming demo. Outlook 2003 helps new users with its simplified menus and toolbars as well as simplified navigation. Contacts, calendar, and tasks are accessed with a single click from the Navigation pane. This allows you to find the information you need to answer messages and schedule appointments quickly. Read messages regardless of the connection. The new Cached Exchange Mode downloads messages and other Outlook 2003 data to your computer so you can remain productive during network downtime. Cached Exchange Mode requires a connection to Exchange Server 2003. Next, a look at the Outlook 2003 interface.

Favorite Folders Organização por conversação Painel de Visão (Direita) Search Folders Here is a sample screenshot of the Outlook 2003 interface. Favorite and recently used folders can be accessed here. You can arrange messages by conversation, allowing a threaded view of related messages. The right-hand preview pane allows for easy readability. Quick Flags enable you to quickly categorize messages with color-coded flags to track messages that require attention. You decide what the flag colors mean, and can use them to create a task list right in your Inbox. Launch calendar, contacts, and tasks from the Quick Navigation pane. Search Folders help you group messages without having to move or copy them. The folders display results of common search queries and provide links to the actual messages residing in the folders. Next, more about Quick Flags. Quick Flags Painel de Navegação Rápida

Quick Flags Gerenciamento e priorização de mensagens Seis cores diferentes de Flags Você decide o que cada cor representa Você pode criar lembretes Processo de leitura e triagem melhorado Mensagens com Flag aparecem no Search Folder em “For Follow Up” You no longer have to keep all messages in your Inbox to remind you of action items. Instead, use Quick Flags to flag messages by priority or time sensitivity and find them in whichever folder they reside. There are six flag colors that you can use to help you quickly categorize flagged messages. You decide what the colors mean. Clicking any of the flags automatically flags the message for follow-up, you can adjust the flag message and set reminders for the flag if you wish. Quick Flags are seamless and easy to use and will not interrupt your reading/triage process. Set a flag with a single click, and use different colors to identify different response requirements. You can quickly do this as you triage your , and by doing so create a to-do list right in your Inbox. Flagged folders will automatically be available in the "For Follow Up" Search Folder. Next, let's talk some more about Search Folders.

Search Folders Provê flexibilidade na organização de s Busca instantânea Funciona como um folder mas é uma view Atende a diferentes níveis de usuários Iniciante: Search folders padrão Intermediário: Templates de search folders Avançados: Qualquer query que se possa imaginar Search Folders are a way to save the results of commonly used searches instead of having to re-run common searches each time you need them. Search Folders are virtual folders that provide a way to keep related s together, without moving them to other folders. They are a live search that acts like a folder in other words. Outlook 2003 can help you create and save Search Folders. For example, if you have messages from a specific person you wish to keep together—and some of the messages are in your Inbox, some are in folders related to specific departments, and others are in your Sent Items folder—you can create a Search Folder that displays all the messages in one place. The messages themselves aren't moved into the folder; they remain in their original locations. But the Search Folder can quickly group, locate, and access them easily with a few simple clicks. Search Folders can be used by anyone, regardless of their level of expertise. Beginners can use pre-made Search Folders, while intermediate and advanced users can create their own. You will see Search Folders in the upcoming demo. Next, new improvements with Outlook and network connectivity.

Conectividade no Outlook Versões anteriores Assumiam que a rede era perfeita e veloz Modo default era on-line Modo off-line ajudava mas nem tanto Experiência de sincronização remota extremamente incômoda Soluções (Exchange Server Outlook 2003) Cached Exchange Mode RPC (Remote Procedure Call) sobre HTTP Older versions of Outlook have historically had problems dealing with adverse network conditions. These versions of Outlook have assumed a fast, responsive, and completely reliable network. The default operation mode was Online, which was chatty and fragile. The user interface often hung and was unable to recover from temporary loss of connection. Offline mode helped, but not while Outlook was transitioning from an online to an offline state. Another issue with previous versions of Outlook was remote synchronization. It was cumbersome to try to synchronize Outlook over a low-speed connection, such as a dial-up connection from a phone line. In most cases, users had to VPN into the corporate network in order to synchronize the Outlook client, or use an alternative client such as Outlook Web Access. Exchange 2003 and Outlook 2003 offer new solutions to alleviate these problems. You'll hear about Cached Exchange Mode and RPC over HTTP in upcoming slides. Let's look at Cached Exchange Mode now.

Cached Exchange Mode Sincronização melhorada Gerenciamento de alteração de conectividade Baixo consumo de largura de banda Gerenciamento de alteração de esquema de energia Resolução de problemas de conflito Outlook 2003 and Exchange 2003 are designed to perform over slow, latent, or poor network connections. When an Outlook account is configured to use Cached Exchange Mode (the default), Outlook works from a local copy of a user's Exchange mailbox stored in an Offline Folder file (.OST file) on the user's computer, along with the Offline Address Book (OAB). The cached mailbox and OAB are updated periodically from the Exchange server. Cached Mode improved synchronization by sending fewer bytes over the wire with fewer round trips. Other features that improve synchronization are: Bi-directional data compression Increased buffer sizes Partial item upload Check-pointing Skip Bad Item Smart sync ordering on the folders Syncs initiated on user navigation Most recent items first (LIFO) within a folder Drizzle and header sync if you just want to do headers on the messages Cached Mode handles connectivity changes efficiently—Outlook just keeps working when the network goes away. While offline, there are no annoying error messages. Your data is available, and you can create new items and modify existing items. In the background, Outlook continuously tries to re-connect to the Exchange 2003 server. Cached Mode is bandwidth-conscious. On fast networks, Outlook will download full items on all folders and address book updates. On slow networks ( < 128 Kb), Outlook synchronizes only "headers" on all folders—headers are small but contain sufficient information to render views. You can still triage your mail, such as downloading important messages and delete junk mail. Cached Mode handles power state transitions. If the system enters Hibernate or Standby mode, Outlook terminates its connections and saves the state for resume later. When the system resumes, Outlook starts quickly against local cache and attempts to connect and sync with the Exchange Server in the background. The Conflict Resolution Engine prevents the generation of spurious conflicts in reminders and follow-up flags. Genuine conflicts automatically resolve with no user intervention. Conflicts no longer interfere with software like ActiveSync, and there is a special conflicts folder that contains alternate versions. Next let's look at RPC over HTTP.

RPC sobre HTTP – Exemplo de Topologia Exchnage 2003 Front-End Server RPC/HTTP Exchnage 2003 Back-end Server RPC/HTTP Outlook 2003 and Exchange 2003 are designed to perform over slow, latent, or poor network connections.

Melhorias no PST/OST Suporte a UNICODE Outlook irá usar UNICODE se o servidor suportar OST: Off-line ou Cached Mode PST: Auto-arquivamento PST’s existentes não são convertidos Novo limite de tamanho ( > 100Gb ) Tamanho default é 10Gb Tamanho pode ser controlado através de GPO (registry) Outlook 2003 supports Unicode and provides full support for multilingual data. If you work in a multinational organization or share messages and items with people who use Outlook on systems that run in other languages, you can take advantage of Unicode support in Outlook. Outlook 2003 can run in one of two mailbox modes with an Exchange messaging server: Unicode or non-Unicode. Unicode mode is recommended and is the default mode if the configurations of the user's profile, Exchange server, and administrator settings allow it. The mode is automatically determined by Outlook based on these settings, and it cannot be changed manually by the user. An administrator can deploy settings that can change the default behavior or limit the ability of users to use Unicode. Running Outlook in Unicode mode with Exchange Server also helps ensure that, by default, Offline Folder files (OST files) and Personal Folders files (PST files) used in the Outlook profile are able to store multilingual Unicode data. In addition, a new file format for Outlook files that supports Unicode can store more data than file formats from earlier versions of Outlook. The new size limit on OST and PST files is over 100 gigabytes. The default size is 10 gigabytes, but it can be changed through system policies. To summarize, here is a list of features that are available to the Outlook 2003 client when working with Exchange 2003. How to configure the size limit for both (.pst) and (.ost) files in Outlook 2003

Find people by searching the Global Address List and contacts, then establishing calls and sending to them. With OMA you can view and create appointments or meetings in your calendar, reply to meeting requests and cancellations, and accept, mark as tentative, or decline appointments. Manage tasks and update notes. Search the Global Address List and add people to your contacts list. Next, more information on Exchange up-to-date notifications.

Demonstração Navegação no OWA e Funcionalidades Outlook Web Access (OWA) is improved. The goal was to make it as close to the full client as possible, and most of the new features of Outlook 2003 are available in OWA. You have the same Navigation pane. You have similar navigation buttons. The Inbox pane is used here as well. As is the Reading pane. You can show or hide the Reading pane. The Two-Line View allows you to preview messages in the Inbox pane. You can also arrange messages in the Inbox pane as you can in the full Outlook client. It's also easier to perform common arrangements like "Received by." Clicking Received again changes the sort order. The same functionality is built into the From button. Flags are supported in OWA. You can assign flags and mark them complete. OWA also supports context menus. If you right-click a message, you get a context menu with common options: Reply Reply to All Forward Follow Up Flag Complete Clear Flag Mark as Unread Delete Move/Copy to Folder You can also mark messages as read or unread. Folders in the Navigation pane also have context menus. You can: Update Folder Open Open in New… Move/Copy Rename New Folder Context menus are also available in message composition windows. Now it's easier to look up contacts, or to find the properties of a recipient from the address book. You can also add recipients to your contacts. You can use the calendar as with previous versions of OWA. Side-by-side calendars aren't available. Now you can do tasks through OWA. You can access Public Folders as you did before. You can also create and configure Rules through OWA. You have many configuration options available in Outlook Web Access. You have the options from previous versions, such as the Out of Office Assistant. In addition, you have many new options. Outlook Web Access can now notify you when new mail arrives. You'll see that in a few minutes. You can configure a default signature when sending new mail with OWA. You can configure the Reading pane. Outlook Web Access 2003 also features a spell checker. You can configure spell checking options here. For example, you can choose to always check spelling. You also have to configure the spell-check language. You can adjust the color scheme. The default is light blue, and you can choose olive green, sliver, burgundy, and dark blue. For this demonstration, burgundy will do. You can see the new color scheme already. Now send a new message to yourself. The word "test" is intentionally misspelled. You can see that OWA has added the auto-signature. Since the message contains a misspelled word, the spell checker pops up. You can change to a correctly spelled word. Since this is a message to yourself, OWA will notify you when the message arrives. The new message notification appears in the lower right, and you can click it to refresh the Inbox view. You can also log off by clicking the Log Off button.

Características de Segurança do Exchange Server 2003
Junk (Spam) x Vírus Vírus Junk Exploits Vulnerabilidade específica (Exemplo: Buffer Overruns) Vulnerabilidade dos sistemas de Efeitos Destrutivo Incômodo, ofensivo Identificação Assinaturas, determinística Várias, Assunto do Custo Perca de dados e produtividade Custo de Help-desk Administração Recursos do sistema Largura de banda Perca de produtividade Solução Infra-estrutura Exchange Plug-ins anti-vírus Exchange features Plug-ins anti-spam Two of the biggest problems in today are junk (unsolicited commercial or spam), and viruses passed through . Viruses generally exploit a specific vulnerability in an operating system or device, while junk mail takes advantage of the general openness of a mail system. Viruses are often destructive, while junk mail generally falls into the nuisance or offensive category. Of course, there are exceptions. Viruses cost you money due to data loss or destruction, productivity loss while a user's terminal is inoperable and while Helpdesk personnel troubleshoot the problem, etc. Junk can lead to many similar situations. You can address both of these problems with a proper Exchange infrastructure in place and with third-party antivirus and anti-spam plug-ins. Next, how do you classify whether an is junk or not?

Requisitos corporativos anti-spam Positivação falsa é a principal preocupação corporativa s válidos tratados como Junk (perca de dados) Bloqueio do máximo no gateway Usuário não é atingido Redução do impacto administrativo Solução end-to-end Fácil de gerenciar Controle balanceado entre a corporação e o usuário False positives are the one enterprise concern when attempting to control spam. No-one wants a valid to get moved to the junk folder. If it does, that message is as good as lost. The best method for dealing with junk is to block at the gateway whenever possible so that the user never sees it. This reduces impact on bandwidth and other system resources. It is important to come up with end-to-end solutions that are easy to manage and balance corporate and end-user control. How can your enterprise deal with junk ?

Exchange 2003 Anti-spam IMF (Inteligent Mail filter) – SP1 Protege através do SMTP Connector no gateway SMTP Filtro de conexão Baseado em IP Configuração global para bloqueio ou liberação de listas Filtro de envio Mensagens de um usuário específico ou domínio Mensagens com remetente em branco Verificação de remetentes anônimos Filtro de recipiente Mensagens enviadas para recipientes inexistentes Permite envio para Listas de Distribuição de usuários autenticados Exchange 2003 offers IP-based connection filtering and global Allow and Deny lists that can help you control junk . Connection filters allow you to specify domain names from which you will not accept . Sender filtering filters messages sent from particular addresses or domains. You also have the ability to filter messages with blank senders, and drop connections if spam is detected. Exchange 2003 includes the capability for recipients to verify whether a message was from an authenticated or anonymous sender outside the organization. This helps users to understand whether a message originated from a user spoofing a sender address. Recipient filtering filters messages sent to particular recipients (valid or invalid). This allows administrators to restrict messages sent to particular internal addresses. Next, Exchange 2003 antivirus.

Exchange 2003 Anti-vírus Nova API de anti-vírus, versão 2.5 Anti-vírus pode rodar em servidores que não tem mailbox’s Suporte a novas características para anti-vírus Delete de mensagens Envio de mensagem de volta para o remetente Exchange 2003 supports the new Antivirus API 2.5 Exchange 2003 improves the virus-scanning API by allowing antivirus vendor products to run on Exchange servers that do not have resident Exchange mailboxes. Antivirus vendor products are allowed to delete messages and send messages to the sender in the Exchange 2003 AV API 2.5 version. Next, the new features of Outlook 2003 security and privacy.

Outlook 2003 Segurança e Privacidade Safe Senders allows you to specify addresses that are safe. Messages from these addresses are never treated as junk . You can add any addresses you like. You can also have Outlook treat anyone in your Contacts as a Safe Sender. Use the Safe Recipients list if you belong to mailing lists or distribution lists. You can add these names to your Safe Recipients List so any messages sent to these addresses or domain names will never be treated as junk messages, regardless of the content of the message. The Blocked Senders list allows you to add addresses or domains that will always be treated as junk . Here you can see an address has been added.

Outlook 2003 Segurança e Privacidade This is the Security tab on the main Outlook 2003 options screen. As with previous versions of Outlook, you can configure default options for encrypting and digitally signing messages. You can also configure security-zone settings. These are the same security-zone settings you find in Internet Explorer. The Download Pictures section is new in Outlook This refers to pictures you see in HTML-based messages such as advertisements sent through . This section allows you to adjust how Outlook will process HTML message content. This is important because messages in HTML format often include pictures or sounds. Sometimes these pictures or sounds are not included in the message itself but are instead downloaded from a Web server when the message is opened or previewed. When this happens, junk senders often use this capability to their advantage by including something called a "Web beacon" in these messages. A Web beacon notifies the Web server when you read or preview the message, validating the address and often resulting in more junk messages being sent to you. So this helps protect you from getting more junk . As with previous versions, you can publish, import, and export, as well as get a digital ID from this tab. The digital ID is used to sign and encrypt messages. Next, Outlook Web Access security and privacy.

OWA Segurança e Privacidade Suporte a Secure Multipurpose Internet Mail Extensions (S/MIME ) Permite encripitação e assinatura digital Junk e Filtro de remetente Similar ao do Outlook 2003 Log Off automático Inatividade automaticamente fecha as sessões Bloqueio de anexos Outlook Web Access supports S/MIME (Secure Multi-Purpose Internet Mail Extensions), a secure method of encrypting and sending . Outlook Web Access has similar privacy and junk protection features to Microsoft Office Outlook You can manage junk lists, safe senders, blocked senders, and trust from your Contacts. You can also block external content in HTML messages. Enabling this option can help protect your privacy because it helps prevent the sender from verifying your address and targeting you with more junk . Another new feature is automatic log off. OWA will detect when your session has gone inactive and log you out safely. Outlook Web Access now supports attachment blocking.

Since from the Internet poses the biggest security threat, in terms of virus propagation and junk , many security settings are configured on the SMTP Virtual Server object. This is the SMTP Virtual Server object. You can have multiple SMTP virtual servers and configure security settings for each virtual server. You can turn on SMTP logging to capture more information about SMTP message processing on the system. Logging can be helpful, because you can capture the IP Addresses and host names of servers sending mail to you. If a denial of service attack is launched against your system, meaning that someone is flooding your system with SMTP mail, then you can use the logs to determine the IP address or addresses of the sending system. Enable logging on the General tab. You can add as many extended logging options as you'd like. To track SMTP interactions effectively, consider adding the client IP address, user name, server name, server IP address, server port, protocol status, protocol substatus (this will give you information about the SMTP commands being used), bytes sent, and bytes received. This should be enough information to determine the address of the sender and the size of messages they're sending. You configure many security options on the Access tab, including authentication methods. Anonymous access is allowed by default, and that is the correct configuration for a public SMTP server because SMTP servers sending SMTP mail typically do not authenticate to send Internet mail. Use this check box to resolve anonymous s to their display names. By default, Exchange 2003 prevents spoofing, or forging identities, by requiring authentication before a sender's name is resolved to its display name in the global address list (GAL). You can override this setting by clicking the Resolve Anonymous check box. This is a new feature in Exchange Server 2003. This is not recommended; if you configure an SMTP virtual server to resolve anonymous s, it is possible for unauthorized users to send with the forged addresses of legitimate users. Because this now resolves to its display name in the GAL, it is more difficult to distinguish a legitimate sender from a forged address. If you have a configuration between business partners, or some sort of restricted configuration where only specified people are allowed to send, you can now configure Submit and Relay permissions for users and groups. This is a new feature in Exchange Server 2003. You can use the Permissions for Submit and Relay dialog box to allow or deny both Submit and Relay based on user or group. If you disallow anonymous access, the default permissions allow the Authenticated Users group to submit messages. A clarification is in order here. "Submitting" means sending a message that will be delivered to a recipient inside the Exchange organization, while "relaying" means using this SMTP virtual server to send a message to an external domain. You can add a certificate to this virtual server in order to use Transport Layer Security (TLS) for authentication and encryption when sending and receiving. Use the Connection tab to configure IP address and domain name restrictions. Again, with a public SMTP server, you shouldn't configure any IP address or domain name restrictions as with previous versions of Exchange. You might configure these types of restrictions if you wanted to restrict which clients and servers could use an SMTP virtual server. You can also configure relay restrictions. Relaying is the act of submitting a message to this SMTP server that is destined for a different SMTP server. Relay is a security concern because junk is often sent from—and SMTP-based denial of service attacks are often launched by—malicious users who relay their messages off of a valid SMTP server. By default, only users who authenticate are allowed to relay messages. You can configure additional relay restrictions to specify computers by IP address, subnet, or domain that are allowed or disallowed from relaying. You can also clear the option to allow computers which authenticate to relay. If you do, you can configure submit and relay permissions for users and groups from this dialog box. The default setting is recommended for most environments. You can also configure outbound security if you have a secure environment where your SMTP server must authenticate in order to deliver messages to partners or other entities. Use the Outbound Security tab to configure authentication methods, as well as Transport Layer Security (TLS). TLS is the new generation of technologies that replace Secure Sockets Layer (SSL). There are several new features in Exchange Server 2003 to help stop junk before it gets into the system. You configure these on the General tab of the virtual server. You can configure sender filters, recipient filters, and connection filters. Before you can enable these, you have to configure the filter rules under Global Settings. This where you configure connection filter rules. Connection filters block the IP addresses of connecting SMTP servers that are found on lists provided by a Block list provider, or that are configured in your global Deny list. For example, you can create a connection filter that will deny all messages coming from the contoso.com domain. You can even configure a custom error message to return, perhaps with an informational or legal message. You can also configure a custom return-status code. You can also configure exceptions. This allows you to configure valid recipients, regardless of whether those recipients are on a Block list. You might use this to add a postmaster account at the blocked domain. This will allow mail administrators from both domains to exchange . You can configure Global Accept lists here. You can configure Global Deny lists here. Both Accept and Deny lists allow you to specify IP addresses. For virtual servers where the rule is enabled, mail will always be accepted from IP addresses on the Global Accept List, and always denied from IP addresses on the Global Deny List. You can use recipient filtering to block to any recipients who are specified on the recipient filter list. In this example, messages to DorisH would be rejected, even if she is a valid recipient in the organization. You can also use recipient filtering to block that is destined to invalid recipients, based on an Active Directory lookup. Be careful since enabling this check box can potentially allow senders of junk to discover valid addresses in your Exchange organization. That's because, during the SMTP session, the SMTP virtual server sends different responses for valid and invalid recipients. The Sender Filter list is a list of defined addresses or address spaces. You can use sender filtering to add or modify domains or users who are not allowed to deliver to your organization. In this case, you can filter all messages with an address suffix of denied-domain.com. You can also define explicit messages like You can opt to archive filtered messages for regular review. You can also filter messages with a blank sender. This is a good idea, as junk often has a blank sender. You can drop the connection if you find a match, which will save transfer time and message processing. This can improve performance if you are receiving a lot of junk . If you clear the "Drop connection if address matches filter" check box, you have the option to accept messages without sending a non-delivery report (NDR) from being returned to the sender of filtered messages. Use this option if you do not want senders of filtered messages to know that their messages were not delivered. Once you have the rules in place, enable the rules on the SMTP Virtual Server. Microsoft Office Outlook 2003 supports many new security features, including features that help prevent junk and protect your privacy. On the Preferences tab, you can set options for identifying and processing junk by clicking the junk button. The new Junk Filter replaces the Rules used in previous versions of Microsoft Outlook to filter messages. The Junk Filter feature is on by default, and the protection level is set to Low, which is designed to catch the most obvious junk messages. Any message that is caught by the Junk Filter is moved to a special Junk folder, where you can retrieve or review it at a later time. You can make the filter more aggressive, which may mistakenly catch legitimate messages, or you can even set Outlook 2003 to permanently delete junk messages. You can configure the following options: "No protection" turns off the automatic Junk Filter. Outlook continues to evaluate messages by using domain names and addresses on your Blocked Senders list, and messages will continue to be moved to your Junk folder. "Low" is useful if you don't receive many junk messages and want to see all but the most obvious junk messages. "High" should be used if you receive a large volume of junk messages. However, you should periodically review the messages moved to your Junk folder because some wanted messages may be moved there as well. "Safe Lists Only" offers the most protection from junk . Any messages sent from someone not on your Safe Senders List or sent to a mailing list not on the Safe Recipients List will be treated as junk . You can also configure Outlook to permanently delete suspected junk instead of moving it to the Junk folder. Safe Senders allows you to specify addresses that are safe. Messages from these addresses are never treated as junk . You can add any addresses you like; in this case will be added. You can also have Outlook treat anyone in your Contacts as a Safe Sender. Use the Safe Recipients list if you belong to mailing lists or distribution lists. You can add these names to your Safe Recipients list so that any messages sent to these addresses or domain names will never be treated as junk messages, regardless of the content of the message. The Blocked Senders list allows you to add addresses that will always be treated as junk . In this case, the address will be added. As with previous versions of Outlook, you can configure default options for encrypting and digitally signing messages. You can also configure security-zone settings. These are the same security-zone settings you find in Internet Explorer. The Download Pictures section is new in Outlook The pictures they're talking about are the pictures you see in HTML-based messages. You see these frequently in advertisements sent through . This section allows you to adjust how Outlook will process HTML message content. Why is this important? Messages in HTML format often include pictures or sounds. Sometimes these pictures or sounds are not included in the message itself but are instead downloaded from a Web server when the message is opened or previewed. This is typically done by legitimate senders to avoid sending extra-large messages. Junk senders have used this capability to their advantage, however, by including something called a "Web beacon" in these messages. A Web beacon notifies the Web server when you read or preview the message, validating the address and often resulting in more junk messages being sent to you. Thus, this setting helps protect you from getting more junk . When Outlook blocks automatic picture downloads, areas in the message that should have a picture will appear as a red X placeholder instead, along with text explaining that Outlook has prevented automatic download of the image. You can right-click on the area and choose to download the pictures. You can opt to permit this type of content from safe senders and recipients. This is the default option. Outlook can also warn you before downloading content; again this is the default. As with previous versions, you can publish, import, and export, as well as get a digital ID from this tab. The digital ID is used to sign and encrypt messages. Outlook Web Access also has new security features. Outlook Web Access now supports Secure MIME (S/MIME). You can run the S/MIME setup from the options page in Outlook Web Access. In the Security section, click Download to download the S/MIME component. Once it's installed, you can choose to encrypt the contents and attachments for outgoing messages and add a digital signature to outgoing messages. In addition to setting up S/MIME support, you must have a digital certificate for these features to work. Outlook Web Access has similar privacy and junk protection features to Outlook 2003. You can manage junk lists and add Safe Senders. Notice that the Safe Sender you configured earlier is visible in this list as well. You can configure to trust from people in your Contacts. You can also configure blocked senders. Again, notice that the blocked sender configured earlier is visible here. You can also block external content in HTML messages. Enabling this option can help protect your privacy because it helps prevent the sender from verifying that your address is valid, making you the target of more junk . Slide 37 This session covered a lot of ground. To summarize, these are the things you should remember. Exchange 2003 features many new useful management features. Outlook 2003 is more powerful and easy to use than ever. Many of the new features of Outlook 2003 can only be used when the client is working with Exchange Server 2003. Mobile browser-enabled devices can take advantage of many features with Outlook Mobile Access. An Exchange infrastructure in place is the first step in dealing with spam and viruses. There are several important new security features in Outlook 2003 and Outlook Web Access. For more information…
