Exchange Server 2003 SP2 includes Exchange ActiveSync, the synchronization protocol that keeps the Exchange mailbox synchronized on client mobile devices. By default, Exchange ActiveSync is enabled.

Exchange Server 2003 SP2 contains new features that work with the Windows Mobile 5.0 Messaging and Security Feature Pack to help you to improve the deployment, security, and management of mobile devices.

Note

To use mobile devices with the Windows Mobile 5.0 Messaging and Security Feature pack, you must upgrade your front-end Exchange server to Exchange Server 2003 SP2. Back-end Mailbox servers can remain at Exchange 2003 RTM or SP1. However, we recommend that you upgrade both front-end and back-end servers to take advantage of the updates in SP2.
