Hi ,
Is it recommend to remove Previous Exchange version's Security Groups from AD. Migrated Exchange 2010 to 2013 last time and noticed that there is some security groups from previous exchange version 2010 such as Exchange Public Folder Administrators , Exchange Recipient Administrators , Exchange Servers , Exchange Services , Exchange trusted SunSystem , Exchange View-only Administrators , Exchange Windows Permission and ExchangeLegacyInterop . Wanna to know if deleted one of these security groups , it might affect to operation and running services. Please advise.
Thanks
Aung
