I have a new client who has had me do some due diligience on their O365 environment.  In that process I've foud one fo the mailboxes is corrupt, and has lost access to content in the mailbox.

Given O365 has no ability to run a mailbox repair, are there other alternatives to exporting what is recoverable, deleting and recreating the mailbox?
