I have been using Outlook for Mac 2011 for about two years now. A few days ago, when I opened Outlook, all my emails and folders disappeared.

I am still able to access my Inbox emails and folders via Office 365; it's just that my Outlook can't seem to access anything.

No, I didn't do anything special to my Outlook account on this computer.

How do I get Outlook to get the emails and folders again without my having to log in to Office 365 on a web browser?

Thanks!
