Pervasive Productivity Scenarios

The flexible options for information access and the new ways to stay connected enable knowledge workers to be more productive and in control when and how they communicate.

- Mobile workers, such as sales and service staff using portable computers and running Outlook 2003 over a wireless network, are free to roam and communicate. Companies do not need separate deployments for mobile features nor do they need to purchase or maintain separate mobile servers. Mobile features are now enabled on all back-end and front-end Exchange servers. When wireless access is lost there is no need to despair. Outlook 2003 is designed to work over slow and poor network connections: Mobile workers are shielded from network issues and can continue working with their Exchange Server information while Exchange Server and Outlook use the available network resources.

Windows Mobile–based devices, such as Windows Mobile–based Pocket PCs, come with the Exchange ActiveSync client and Microsoft Office Outlook Mobile built in, which enables you to sync your e-mail messages, calendar, and contacts lists directly with Exchange Server 2003. Exchange Server administrators can enable this from the same screen used to manage Exchange Server e-mail accounts.

Similar to Outlook Web Access for desktop browsers, Outlook Mobile Access is designed for security-enhanced access from mobile device browsers. With Exchange Server 2003, users can gain access to their mailboxes from mobile devices with HTML, XHTML (WAP 2.x), and CHTML-based microbrowsers.

- Remote workers can work at home, a satellite office, a customer site, an 802.11 hot spot such as their local Internet café, and can use Outlook Web Access from any Internet-connected computer to gain security-enhanced access to Exchange Server. Outlook Web Access in Exchange Server 2003 has been improved for easier use, speed, and greater security. The latest features in Exchange Server 2003 have been extended to any browser-based computer, including non-Microsoft operating systems, including:

- Spelling checker
- Task list support
- HTML and attachment blocking to help prevent spam and potential beacon-finding code
- Automatic logoff. The inactivity time-out automatically logs off and closes out your session.

With the new UI, most users have to look twice to see if they are using Outlook 2003 or Outlook Web Access. You also get support for S/MIME in Outlook Web Access so that you can digitally sign and encrypt your e-mail messages.

Working remotely but still want the use of the full Outlook client? In previous versions of Exchange Server, using the full Outlook client connecting over the Internet required a virtual private network (VPN) connection. Now, Outlook 2003 users can easily connect over the Internet to their Exchange servers using HTTP or HTTPS without the need for a VPN connection. This translates to another saving for the IT department.

- Traveling workers can run Outlook 2003 from their hotel or between flight connections over a dial-up line and synchronize their e-mail messages. With the latest synchronized Exchange Server data, they can continue working offline until their next opportunity to dial in and reconnect. Outlook 2003 and Exchange Server 2003 help them to be productive online and offline.

- All workers can take advantage of Windows Mobile–based devices to stay on top of things while away from their computers. Pocket PC, Pocket PC Phone Edition, and Windows Mobile–based Smartphones enable you to synchronize your wireless device directly to the Exchange server by using Exchange ActiveSync technology. E-mail messages, contacts, schedules, and attachments are at your fingertips.

Cost Savings with Exchange Server 2003

The Exchange Server 2003 upgrade and administration tools increase your worker productivity and help consolidate your servers to save you money.

Consolidation Scenario

For organizations running Exchange Server 5.5, upgrading presents a great opportunity to lower TCO by:

- Simplifying operations
- Increasing server availability and reliability
- Reducing the time it takes to do backup and restores
- Reducing the number of servers running Exchange Server

Exchange Server 2003 improves upon Exchange 2000 Server with a multiple database design (up to 20 databases per server). Typical Exchange Server 5.5 organizations have 1,000–2,000 users per server, limited primarily because of a single database architecture and the time required for backup and restore operations and management. With Exchange Server 2003, however, the number of supported users and mailboxes can easily be in the 3,000–5,000 range or more, depending upon the user profiles, message traffic patterns, and mailbox size limitations.

Administrative Productivity

Exchange Server 2003 is designed to help your messaging IT staff to be more productive. Ongoing administration of an Exchange Server environment represents about 20–25 percent of TCO for Exchange Server. The new and enhanced tools help your IT staff to do their job more efficiently. For example, an executive might need to recover an old, but very important, e-mail message that was deleted a few months ago. By using the new Recovery Storage Group, an administrator can recover an individual user's mailbox to find the important e-mail message that was previously deleted. Other new administrative features include:
- Move multiple mailboxes in parallel.
- Improved message tracking and Outlook client performance logging.
- Enhanced queue viewer that enables both SMTP and X.400 queues to be seen from the same console.
- New query-based distribution lists that now support dynamic, real-time lookups for members.

Exchange Server 2003 SP2 Overview

Add even better protection, reliability, and easier administration as well as improved mobile messaging to your Exchange Server 2003 messaging environment when used with compatible devices.

Mobile E-Mail Improvements

SP2 offers a huge leap forward in mobility capabilities. With SP2, Exchange Server 2003 can offer a significantly improved Microsoft Outlook experience on mobile devices as well as additional security and device control. As always, the Exchange ActiveSync protocol does not require expensive software or outsourcing fees to access data on your server running Exchange Server.

The mobility enhancements in SP2 give you:
- New seamless Direct Push Technology e-mail experience. No longer is there a reliance on short message service (SMS) to notify and ensure that your device automatically retrieves new e-mail from your Exchange server. SP2 uses an HTTP connection, maintained by the device, to push new e-mail messages, calendar, contact, and task notifications to the device.
- Additional data compression translating to a faster experience when sending and receiving messages and reduced sync times.
- Additional Outlook properties, including support for task synchronization and pictures in your list of contacts. In addition, you can now look up people by using the Global Address List (GAL) over the air.
- Greater control over device security, including:
- Policy setting. Unlock a device with a password.
- Local wipe. Decide how many incorrect logon attempts are permitted before your data might be at risk.
- Remote wipe. Lost, stolen, or misplaced devices are never out of reach. You decide when it’s prudent to reset devices remotely over the Web.

Such policies help to ensure corporate data or applications are not compromised when devices are lost or get into the wrong hands.
- New optional support for certificate-based authentication to eliminate the need to store corporate credentials on a device.
- Added support for Secure/Multipurpose Internet Mail Extensions (S/MIME) to sign and encrypt messages coming to and from mobile devices.

For details about the other mobility features in Exchange Server 2003, see the Mobility in Exchange Server 2003 page.

Most mobile e-mail improvements, with the exception of support for tasks and for pictures in contacts lists, require that your device or the software on the devices be compatible with Exchange Server 2003 SP2. Windows Mobile–based devices require the Messaging and Security Feature Pack for Windows Mobile 5.0.

Licensees of the Exchange ActiveSync protocol can take advantage of these improvements through updates to their messaging applications or devices. The roadmap for those devices is owned and managed by the licensee.

Better Protection Against Spam

SP2 delivers improved protection against spam to help ensure a secure and reliable messaging environment, including:

- Updated and integrated Exchange Intelligent Message Filter. Based on the same patented SmartScreen filtering technology developed by Microsoft Research and now incorporated in Microsoft Office Outlook 2003, MSN Internet Software and Services, and MSN Hotmail, SP2 incorporates the latest data and updates to the Exchange Intelligent Message Filter. Improvements to this filter ensure a continued focus on identifying spam and reducing false positives. These updates include new capabilities in the fight against spam including blocking phishing schemes. Phishing schemes attempt through deception to fraudulently solicit sensitive personal information by masquerading as legitimate Web sites.

- New support for Sender ID e-mail authentication protocol. This new feature further helps prevent unwanted mailbox phishing and spoofing schemes by verifying the IP address of the e-mail sender against the purported owner of the sending domain. Spoofing attacks occur when one person or program is able to masquerade successfully as another to gain access to personal e-mail messages. The result of the Sender ID check is used as input to the Exchange Intelligent Message Filter. The sender must have registered a list of the valid IP addresses in DNS for accuracy. To learn more about Sender ID, see the Sender ID page on the Microsoft Safety site.
