  • Replication, which provides statistical data on replicas.
• Link state improvements.
• Public folder referral.
• Inter-organization Replication tool.
• Move Mailbox tool.

Deployment
Upgrading, migrating, and deploying Exchange Server 2003 is easier and faster with:

• Deployment tools and Help files.
• New cross-site migration tools.
• Public Folder Migration tool (pfMigrate).
• Active Directory Connector tools.
• Internet Mail Wizard.
• Active Directory Connector.
• Setup. Setup is easier with:
  • Outlook Mobile Access and Exchange ActiveSync
  • Setup permission requirement changes that allow additional servers running Exchange Server to be added to an existing Administrators group without the need of a full Exchange Server administrator.
  • An option that enables you to specify a destination domain.
  • Better batch-mode support than in Exchange 2000 Server.
• Active Directory Schema.
• Exchange Server 2003 Connectors.

Increased Mobility
Exchange Server 2003 has built-in mobile features to help drive greater worker productivity by facilitating mobile and remote computing scenarios. New and enhanced mobile and remote access features in Exchange Server 2003 include:

Outlook 2003
Mobile and remote workers can communicate and collaborate on the go, and coupled with the new user interface and security and support features, can communicate and collaborate more productively.

• Cached Exchange Mode.
• HTTP access from Outlook.
• Performance enhancements.

Outlook Web Access
Microsoft Office Outlook Web Access 2003 has been improved for easier use and a closer look-and-feel to Outlook 2003.

• Usability improvements in the user interface.
• Enhanced security when connecting over the Internet. New features include:
  • Session inactivity timeout using forms-based authentication provides support for secure logoff and timed logoff after a period of inactivity, even if the browser is left open with a current session to the server.
  • S/MIME support (Internet Explorer 6.0 and Windows 2000 or later is required).
  • Web beacon blocking makes it more difficult for senders of spam to confirm e-mail addresses. When a user clicks a hyperlink in the body of an e-mail message, Outlook Web Access helps protect private information from being revealed to the visited Web site.
  • Customers can block access to all attachments or specific file types and can allow attachment access only through specific servers.
  • Additional security and deployment improvements can be offered when using Exchange Server 2003 with Microsoft Internet Security and Acceleration (ISA) Server 2004. For more information, see the Better Together: Using ISA Server 2004 with Exchange Server 2003 page.
• Performance improvements to accommodate low-bandwidth situations.

Exchange ActiveSync
Mobile and remote workers can also stay connected while on the move. With ActiveSync built into Exchange Server 2003, Windows Mobile 2002 and later–based devices can synchronize with an Exchange Server mailbox with very little configuration. Synchronization is over-the-air, can be on demand or scheduled, and provides rich access to e-mail messages, schedules, and contacts. New devices that are not Windows Mobile–based and are from companies that have licensed Exchange ActiveSync also provide this capability.

Easier Development
The portal enhancements in Exchange Server 2003 include:

• Exchange 2003 Software Development Kit (SDK).
• Workflow Designer for Exchange.
• New Web Parts.
• Redirection support.
