We have installed Exchange Server 2007 SP2 on different servers except to 3 AD servers. My project is stuck because of some people is informing to me...."After migration oF AD from 2003 R2 to 2008 R2 some features of Exchange Server 2007 is not working properly" Can anyone help me? Is there anyone suggest.....Exchange Server 2007 SP2 Is Supported to the migration Of Active Directory Domain From 2003 R2 to 2008 R2 Server.? Is This Migration is possible or not..?
