I have setup up a completely different Exchange 2003 server and need to transfer the mailboxes from an existing Exchange 2000 server. The new server resides on a different domain with all 2003 servers in Native mode as well as the Exchange 2003. What I planned to do is create identical usernames and mailboxes on the new server. Any suggestions? I tried using exmerge to bring over the mails but have not been able to import them (even individual pst files) into the new server. Thanks, Shawn
