So we are in the middle of our migration to Exchange 2013, and appear to be having issues with migrating users with in-place archives on their mailboxes.
Environment:
Exchange 2010 SP3 RU1
Exchange 2013 SP1 RU1
Clients: Outlook 2010 SP1
The actual move request completes, the user account shows up as expected in the EAC with the archive, however when the user launches Outlook for the first time, only his primary mailbox gets reconfigured successfully. When the Archive -username link is clicked, an error pops up stating that "The set of folders cannot be opened. Server Microsoft Exchange is not available."
If we create a new profile for the user, the Archive connects just fine, but that also means they will have to download their entire OST again. Also, not very practical for 1,500 users with archives.
We have verified that this happens in both directions, i.e. if we move a mailbox + Archive from 2010 to 2013, or from 2013 to 2010. In OWA the archive is immediately available.
Has anyone else seen this in their environment?
Thanks,
Karl
