Our current Exchange environment consists of 3x Exchange 2010 SP2 servers and Windows Server 2008 R2 SP1 domain controllers.
Where do we stand on upgrading the domain controllers to Windows Server 2012, I can't see anything from MS saying this is or isn't a supported scenario?
We have already introduced a 2012 DC into the domain, it is a GC, but doesn't hold any FSMO roles.
The system requirements for Directory Services (http://technet.microsoft.com/library/aa996719(EXCHG.141).aspx) states the highest supported OS as 2008 R2 SP1 and hasn't been updated since July last year.
