My outlook account has frozen

 I only see the first page of my inbox but I can't access any of my messages. I can't move to the next page of my inbox.  I can't log out or click on anything. It seems as if my whole account is frozen apart from the scroll bar on the right which I can move up and down.  I don't have a toolbar either, except for the NEW email button, but it doesn't work.  I managed to get into a couple of emails from my phone yesterday but then after a few minutes that froze too.  I would really appreciate any help, so thanks in advance!
