Exchange 2007 SP3 Is Windows Server 2008 R2 Friendly
A lot of Exchange Server 2007 users just aren't ready to move to Exchange 2010, which while apparently impressive, includes a number of fundamental changes IT must adapt to. On the other hand, many shops are just fine with Windows Server 2008 R2, except that it doesn't run Exchange 2007. That is until now with the release of Exchange 2007 SP3.
SP3 is rather different than SP2, so if you may the move, get your Active Directory experts involved early to make the migration as soon as possible.
