I have a MacBook Air and am running Office 2011.  I moved the "Office 2011 Identities / Main Identity" files into my Google Drive folder, in an attempt to create a backup function for a large amount of Outlook folders I created to store old emails.  When I relaunched Outlook all the folders were gone. I copied the folders back to the place where I found them, but that has not helped.  What can I do to restore them on Outlook?
