Hi,
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.
To add the protection back again, you can reselect the Deny check boxes for the Delete and Delete Subtree advanced permissions for the Everyone group for the OU and the Delete All Child Objects permission for the Everyone group on the parent container. For more information, see Protect an Organizational Unit from Accidental Deletion.
