About three weeks ago I installed a new exchange server at school. I migrated all the mailboxes to the new server. Everything seemed to be fine for about two weeks. Then people tried to access Public Folders via the web and I realized I would need to migrate them sooner than later. I decided the best course of action was to just replicate from the old server to the new server.
When I first setup the replication I was getting an error. I found there was a hotfix and I applied it. Then I setup the replicas. This is where the problems started. It created the folders on the new server, but no content got replicated. I called Microsoft and they tried a few things and told me to wait and see. I wasn't able to check it until much later in the day and still nothing. I called Microsoft back about 4 PM.
I sat on the phone with a PSS rep who if he was in the US had not been so for long. He took remote control of the server and just kept running in circles. No progress seemed to be being made. At about the 3 hour point he brought in an actual MS employee (you can tell by their email address) from the connections group. This engineer checked some of the same things. Eventually we found that Intergrated Authentication was disabled on SMTP. This is what caused it all. Apparently replication (and probably other stuff) needs to send authenticated SMTP messages.
At this point I think everything is replicated. I will check it more on Monday and hopefully fully decommision the old server.
