How do I clone a mail enabled distribution list?
The distribution group would need to be cloned by using a DRA server with the legacy Exchange Managment Tools installed. DRA would need to be configured to manage legacy mail objects with the newer Exchange Management Tools. The distribution group would need to migrated to the newer Exchange Server.
Enabling management of legacy mail objects by DRA will allow a DRA server with newer Exchange Tools to manage older mail objects. Microsoft will update that mail object in such a way as to prevent legacy tools from managing the object in the future.
