Can anyone advise when Unity 5.x Unified and above Will Support AD2008 R2
I just found this here....
Active Directory Requirements—Cisco Unity Unified Messaging
•The Cisco Unity server typically is a member server in an Active Directory 2008, Active Directory 2003 or Active Directory 2000 domain. (Active Directory 2008 R2 is not currently supported. When it is supported, this document will be updated with that information.) All domain and forest functional levels are supported, including the levels formerly known as mixed mode and native mode.
Active Directory 2008 R2 is not currently supported for use with Cisco Unity. You cannot have Active Directory 2008 R2 domain controllers in a forest that contains a Cisco Unity server. When R2 is supported, this document will be updated with that information.
So it isn't currently supported. Not sure what the roadmap is or when it will be tested/supported so far.
