There are two versions available of Exchange Server 2003. Management tools for mailboxes and messages have been improved and Instant Messaging and Exchange Conferencing Server are now separate products. Improved versions of anti-spam and anti-virus were also included. These include Outlook Mobile Access as well as ActiveSync. The Exchange Server 2003 received some features form Microsoft Mobile Information server as well. It allows the server to experience less downtime. There is a new disaster recovery feature that is even better than before. It may also be run on 32 bit Windows Server 2003.
