What's new in Microsoft Exchange Server 2003 Service Pack 2 (SP2?)

Improvements to mobile clients. New Email, Calendar, Contact and Task notifications are directly pushed via an HTTP connection to devices with improved data compression. New policies exist that, if a mobile device is lost or misplaced, a local wipe will be performed after a defined number of incorrect logon attempts, thus preventing unauthorized users from getting access to private information. You can also initiate a remote wipe when needed, rendering the device "as new" with no data. A video is available at http://www.microsoft.com/windowsmobile/_assets/video/teched/final-mobilityv7-2mbps.wvx that shows some of the new mobile functionality.

Improved spam protection. SP2 includes an updated Intelligent Message Filter (IMF), as well as support for the new Sender ID email authentication protocol.

New maximum mailbox store size (up to 75GB)

New offline address book format

The ability to force remote clients to use cache mode

More granular Public Folder replication and permissions management, which includes not allowing a replica of a public folder to be deleted while there is unreplicated data

Support for Novell GroupWise 6.x connectors and migration tools
