So i want to restrict a DL (AllStaff) so that only the Domain Users can use it, no one outside our organization. I would like to use the builtin "Domain users" DL in the AllStaff DL but it wasn't available to be added to the Message Delivery Restrictions. So my question is since the AllStaff DL has all of the domain users can i use the AllStaff DL to limit the users. it seemed to allow me to.
I hope that makes sense.
