Exchange Server 2003 Service Pack 2 (SP2) offers new features and improvements to Exchange Server 2003. New features include support for mobility and message hygiene. Improvements have been made to address performance and reliability with public folders and with database size restrictions. New for mobility is direct push, which is an Exchange technology that maintains an open connection between the mobile device and the server. Remote wipe is another new feature, and it enables administrators to delete sensitive data from a lost or stolen mobile device.
Other features include global address list (GAL) lookup, policy provisioning whereby administrators can make supported policies more secure, support for certificate-based authentication, use of S/MIME to sign and encrypt mail, and server-based synchronization of tasks. This version is the first release on CNET Download.com.
