I recently installed Exchange 2010 on a new box and moved most of the mailboxes there from 2003 on a SBS box. I replicated the folders using PFDAdmin after i could not open them on System Manager on the Exchange 2003 box. I am still running the EX2003 box and need to for a few more months.
Still, i have continual errors on my EX2010 box: Error 14029 in the application log
I also get errors on the outlook client in the Sync Issues folder every 15 minutes:
14:00:37 Synchronizer Version 12.0.6529
14:00:37 Synchronizing Mailbox 'My Name'
14:00:37 Microsoft Exchange offline address book

Couldn't find an Exchange 2010 or later public folder server with a replica for the free/busy folder: EX:/o=First Organization/ou=first administrative group.
