Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

Exchange Server 2003 Service Pack 1 (SP1) offers new updates and improvements to Exchange Server 2003. Enhancements include new language support for Outlook Mobile Access and Microsoft Office Outlook® Web Access spelling checkers, and out-of-office modification, a larger text entry field, search folder support, and improved menu navigation for the Outlook Mobile Access user interface.

Updated deployment tools are included with SP1 to help you with site consolidation. Site consolidation involves moving Exchange servers from remote sites into a larger central site and allowing users in remote offices to access their mailboxes and public folders over the network. Site consolidation provides the following benefits:

• The Exchange topology is simplified.


• You can administer Exchange centrally and reduce administrative costs.


• You can make better use of hardware because there are fewer mailbox servers as well as fewer auxiliary servers. A centralized datacenter can also increase scalability and availability.


• Consolidating sites can help your organization reach the goal of running Exchange in native mode by reducing the number of Exchange 5.5 servers in the organization.


• With fewer mailbox servers, there are fewer targets for security issues.
