Public folder replication Exchange 2003 - 2007
Posted on 2010-11-26
We are in the process of migrating from an Exchange 2003 server to Exchange 2007. Mailboxes are all moved and working fine, but we are now beginning to replicate Public Folders to the new server, and have hit an issue.
We have a few hundred subfolders in Public Folders with folder sizes ranging from 10 Mb to a little over 2 Gb. I have been working my way from small to large, turning on replication subfolder by subfolder, and item counts in the new server increment to match the item counts in the old so it appears replication is happening correctly from old to new. I did not turn on replication in the parent folder yet because I was afraid it would open the floodgates and overwhelm the server. (Both servers are on the local LAN, BTW - no WAN links involved)
The issue is that new emails to mail-enabled subfolders increment the item count in the folder on the 2007 server as viewed in the Public Folder Management Console, but they never show up in Outlook for anyone. It appears that Outlook is only looking at the old server, and new items in the 2007 server are not replicating back to the 2003 server. Both new and old items *are* viewable in OWA, just not users' desktop Outlook (we use Outlook 2003 and 2007 and problem is the same regardless of version).
Is this because I have not enabled replication for the parent folder yet? Or is there a way to force Outlook to look at the new server? In my own Outlook, when I select "Properties for Public Folders" and click the Advanced button the mail server shown is the new 2007 server.
I'm puzzled. Can anyone help?
