I recently added a second Exchange 2003 server and have run into a snag with getting them to communicate with one another. Both show up under my organization servers and I can move mailboxes from one to the other without a problem. However, users who have mailboxes on the new servers cannot send or receive e-mail to users with mailboxes on the original server. The new server mailboxes can also send mail out to the internet but cannot receive mail from the outside.
I have made sure that the original server does not have Smart Host configured and I have added the new server to the bridgeheads on the routing group connector. Both have an SMTP Virtual Server configured identically. The internet mail issue may be firewall related (though I thought mail would be delivered to the original server and then routed to the new one?) but can't figure out why the two servers cannot mail each other.
In a possibly related issue, I am unable to get Public Folder replication to work at all. I have configured replication for "Always". The original server shows "In Synch" but the new one shows "Local Modified". Following other advice I read on here I compared the actual message counts and there seems to be no replication at all happening. This has been about 24 hours. Not a huge amount of time but I should see something I think.
Any advice would be greatly appreciated!
Edit: I should add that I have also completely removed antivirus from both Exchange servers for the time being so as to make sure it wasn't isolating messages or causing a problem. Thank you!
