my outlook “menu bar” disappeared

thinking that would be a good way to remove emails from my Inbox and save them , I clicked "Archive" . all options ( 'Delete' and 'Reply, for example; ) have now vanished from the 'menu " bar. "New" is the only option remaining. WTH? I HATE this Outlook ****!!!!! Hotmail worked perfectly AND was so easy and user friendly that a complete idiot could figure out how to use it. Microsoft, if you absolutely HAD to call it "outlook" why couldn't you just re-name hotmail and leave the rest the way it was-perfectly functional . Incidentally, where did the "forward" option go?
