Initial setup was Microsoft Server 2003 with Exchange Server 2003 installed.
Migrated exchange to the cloud and tried to uninstall/delete Exchange 2003.
System was working fine.
Upgraded Server 2003 Enterprise to 2008 Enterprise. Upgrade seemed to go ok but now I am unable to edit users (add, change etc)
Get snapin error:
Microsoft Active Directory - Exchange Extension
Id no : c007007e
The uninstall of Exchange was not very clean. Directory still exists with many files. Unable to remove with Add/Remove Programs.
