Remove Protection Against Accidental Organizational Unit Deletion

You can use this procedure to remove the following access control entries (ACEs):

• On the organizational unit (OU) for which you are removing protection, remove explicit Deny ACEs for the Delete and Delete Subtree advanced permissions for the Everyone group.
  
  
• On the parent container of the OU for which you are removing protection, remove an explicit Deny ACE for the Delete All Child Objects permission for the Everyone group.
  
  

This removes protection that prevents an OU from accidental deletion. Consequently, you may have to remove these permissions to be able to perform bulk deletions of objects in Active Directory.

Membership in the Domain Admins group, or equivalent, is required to complete this procedure.

To remove protection that prevents an OU from accidental deletion

1. Log on to the computer as a member of the Domain Admins group.

7. Click OK to close the Advanced Security Settings, and then click OK to close OU Properties.

8. Second, clear permissions on the parent container of the OU for which you want to remove protection. To do this, right-click the parent container, and then click Properties.

10. In Group or user names, select the Everyone group, and then clear the Deny check box for Delete All Child Objects, and then click OK to close Container Properties.
