We currently run a network with Server 2003 functional level and Exchange 2003 SP2 and plan to migrate to AD 2008. My question is - can Exchange 2003 SP2 coexist in an AD 2008 environment? Hank Vare

Hi Hank Yes it is supported in all current AD functional levels. Have a look at the matrix here: http://technet.microsoft.com/en-us/library/dbac2d40-da8b-469f-a265-1d1f948fe446%28EXCHG.141%29.aspx Cheers, Steve
