New Outlook missing address

Am I missing something?? What happened to my address books, they now appear as categories.  When I have a large group I need to send an email to, my address book isn't viewable or searchable.  The address books appear and work correctly in the browser and of course in the Windows client.  Am i doing something wrong?  Why are they showing up as categories?  And there doesn't appear to be a way to create new address books....except on a browser or windows client.

The update today forced New Outlook and there's no longer a toggle to go to the old Outlook.
