We are curretnly in the process of updating our Exchange 5.5 server to 2000. We have successfully joined the 2000 server to the 5.5 site and moved over 2 mailboxes. However 2 of those mailboxes are part of a DL that is on the 5.5 server and are not getting mail sent to the DL. any ideas why? Do I have to move that DL to the 2000 server? If I do, what of the other users who are part of the DL that are still on 5.5?
