When trying to move an OU in Active Directory, you get this error:
Active Directory Domain Services
Windows cannot move object “OU” because:
Access is denied.
This is either because Protection from accidental deletion is turned on for the OU you are trying to move, or because you have delegated rights, but no permission to move the OU.
Try moving the OU while logged in as the AD administrator. If you have permission to move the OU, but still get the Access is denied message then you need to disable Protection from accidental deletion on the OU before moving it.
