I have a user for whom I've enabled Exchange Online's Archive Mailbox feature. Archiving has been working fine. However, they're using a version of Outlook 2007 which is unable to display archive mailboxes. I didn't realise that such versions existed prior to enabling archiving. But now I do!
So the user's unable to view their archive from Outlook 2007. Yes, they can see it in Outlook Web App, but they're not happy with that as a solution. So I would like to move everything that's been archived back into their main mailbox.
The way I've been approaching it is to connect to the mailbox / archive mailbox using a fully patched copy of Outlook 2013, and then attempt to export the archive mailbox to a PST. This mostly works, but it's been tending to fail part way through the process with a "Network Problems" type message, since it's an online connection rather than a locally cached one.
Is there a better way of doing this? Something like a Import-ArchiveBackIntoMailbox Powershell command, maybe?
