I've lost all my emails, including emails I had in folders.  I am unable to recover any of the emails using the recover deleted emails button (was set inadvertently to "not recover" and is currently set to recover deleted emails).  I had downloaded all mail to Office Outlook, deleted current mail in the inbox online, and when I downloaded the one email in inbox that had not downloaded into Office Outlook (did not request sync for all mail, just "download inbox"), all offline mail was deleted.   Please help.
