Microsoft gets security message
eWeek | at | by Mike
Microsoft Exchange Server 2003 Beta 2, the first public beta release of Microsoft Corp.'s enterprise messaging platform, shows incremental, but useful, im-provements over its predecessor, Exchange 2000.
Exchange 2000 introduced AD (Active Directory), which requires customers upgrading from 5.5 to 2000 to change their entire messaging architecture. Exchange Server 2003 also uses AD, so a migration from Exchange 5.5 to Exchange Server 2003 would be just as challenging, but there are no drastic implementation changes for sites moving from Exchange 2000 to the next version.
