We are currently on WIndows 2003 SBS and are migrating to Windows 2008 R2 with Exchange 2010. I've setup a test environment using VMware and followed this great article below. Most things seems to be working except for public folder replication.
I've added the Exchange 2010 server to be a replica using this article http://www.petenetlive.com/KB/Article/0000426.htm
since we have a lot of nested folders.
However, only a few of the folders were synced and some of those folders do not have all the items. If I select each public folder and resend the changes for the last 9000 days, then the folder on Exchange 2010 gets updated. However, it is not doing it automatically although the replication is always set to run and the message priority is urgent for all the public folders.
If I look at the replication status, the status for Exchange 2003 is synced and Exchange 2010 is local-modified. Any thoughts on what else I could check on? Thanks.
