I have setup and added Exchange 2003 on a Windows 2003 server to an existing Exchange 2000 site on a Windows 2000 server and have been moving mailboxes with no problems. Also there has been no mailbox access issues. When I try to setup replication for the public folders to Exchange 2003 there are no errors yet nothing is replicating. I have even set it to immediate, urgent and nothing has happened and its been over a week. I even checked with and followed MS Articles Q288150 and Q307917 and couldn't find anything else on this. Any ideas? I eventually want to move the smtp connector and remove the old Exchange 2000 from the site.
