Outlook Calendar Ribbon Moved To Side. How do i put it back? My outlook shows a bar on the left side that goes vertical with icons for mail, people, calendar, tasks.

After an update of office, outlook now displays the navigation buttons for mail, calendar, contacts, tasks, etc… on the left side next to the folder list. In my outlook desktop app, the reply and reply all and other stuff is now to the right instead of at the top.
