Even it is supported in windows server 2008 R2 DC.http://msexchangeteam.com/archive/2009/09/02/452284.aspxAndwindows server 2008 SP2 OS for exchangeis also supported.But you need to waitfor install exchange2007 SP2 on windows server 2008 R2 OS.http://msexchangeteam.com/archive/2009/11/04/453026.aspxFrank Wang
