After running Outlook this morning (in a sleep state) I was given a chance to "try" the new Outlook. I foolishly accepted not realizing that it was not "trying" but rather an actual upgrade without return! I ended up with a completely blank Outlook: no accounts, no email folders, no contacts, and no calendar events!

Can someone please help me revert to the previous version or at least show me where I can find information on importing my old data?

All help is much appreciated.
