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.
In order to fix this, click on View > Advanced Features and then right-click > Properties on the OU – When the window appears click on Object and untick the “prevent from accidental deletion” box.
If this box has already been unticked then you will need to amend permissions for that OU. Right-click > Properties on the OU and a window will open.
Click on the Security tab and then Advanced, you will need to add your account or group and give it your desired permissions.
This should resolve your issue.
