I tried the Beta for Office 365 backup and noticed that the archive mailbox is not being backed up. I noticed this when trying a test restore I was not given the archive in the mailbox tree.
Did I do something wrong or is this not supported in the beta?
I have also noticed that you need an account with a license assigned to it in-order to connect to an organization.
As SMB would have it, they would usually pay for the mailboxes they actively use only and not for their subcontracted IT admin team

Is that a limit of O365 or do I need to enable some special permissions in on the account I am using?
