We are running Unity 4x with Exchange 5.5. Unity AD is integrated with the domain AD. But Exchange is not, in fact the entire company runs Exchange 2003, whereas Unity uses Ex 2K3.
Problem is - Exchange Team is planning to run Exchange in " Native mode" & shift away from current "Mixed mode". Will this affect our Unity since it's integrated with domain AD. Do we have to upgrade to Exchange 2003 on our Unity box?
