I have just finished installing an Exch2k3 server and added it to the same
site as my Exch5.5 server (part of my swing server upgrade process). Have
moved all of the mailboxes and public folders over to the 2k3 server
successfully. However, when I create a new user now in AD and add a mailbox
(created on the 2k3 server), this user can get local network mail, but no
email form the internet. The 5.5 server is still the first server in the
site. I think this a replication issue, but not sure.
