I've done some significant googling on this- I'd love to be wrong but it seems like no one has had this exact problem before.
I had all my mailboxes and pf's on an Exchange 2003 machine. Built up an Exchange 2007 machine with legacy Outlook clients enabled. Moved mailboxes over, no problem. Went to run the MoveAllReplicas.ps1 cmdlet and it errored saying "Object OldServer\Public Folder Store has been corrupted and it is in an inconsistent state. The following validation errors have occurred:
This is followed by three:
WARNING: The item "xxxxx" in public folder referral does not reference an existing server.
I went back to OldExchange, dismounted the store and ran an integrity check on it. It mounts fine, but now all Outlook clients cannot see any public folders contents.(can see the folder list though) I check this out on 2k3 ESM and all my pf's now only have NewExchange as the sole replica. Adding OldExchange to the replica list enables Outlook clients to see the contents of the pf again.
When I create a totally new PF on NewExchange, Outlook clients can see it on the folder list, but after clicking on it get an error message of: "Unable to display the folder. This folder cannot be opened because there is a configuration problem on the server. Contact blah blah blah..."
This is the same error message that existing pf's had after i attempted the MoveAllReplicas.ps1 cmdlet.
So I think my main problem is that my outlook clients cannot view PF's on my Exchange 2007 box. I'm sure something else is probably wrong, but I'd like to make this work first.
Any and all help is very much appreciated!
