I just completed, or so I thought, a swing migration from single-server 2003 to new server also 2003. There are a lot of mail-enabled public folders. I followed the recommendations of setting up replication to the new server, waiting for replication to complete, and then removing the replicas from the old server. All inbound SMTP traffic is now directed to the new server, and none of the mail-enabled public folders are listed for the old server, when looked at with ESM from either server.
I also changed the routing group to make the new server the Master, the old server the Member. It all looked good, since new messages were arriving in the newly re-homed public folders. As a test, I shut down the old server. And then all public folder messages stopped arriving on the new server. Where were they queued up? On the new server, trying to be sent to the old server! Start up the old server and now the messages are arriving in the new server's public folders. So messages arrive on new server, are then sent to old server, where they then get sent back to new server. WTF? And I did try bouncing all Exchange services on the new server, in case it was caching something or remembering something it shouldn't. No help. What am I overlooking here? Or will this self-resolve when uninstalling Exchange from old server? thanks, Carl
