Title: Exchange 2003 Beta 2 ? Improvements and Questions Summary: Exchange 2003 is supposed to be a minor upgrade of Exchange 2000, mainly delivering improvements based on customer feedback. Exchange 2000, a major leap from Exchange 5.5 had some incomplete features and stability issues. Some features have been added through services packs (STM files virus checking, fault tolerant domain controller access, and more) and some have been saved for the new code named Titanium version. Some of the new features are only available when installed on the Windows 2003 platform, some only when used with the upcoming Outlook 11 client, also in its beta cycle.
