Since upgrading to Mavericks I've experienced connection issues with Outlook.  There has been issues with my inbox synching and mail being sent.  My local Outlook install is connected to an Office 365 account and since our whole company uses Exchange this is a major issue for me.  Does anyone have a fix?  Is this is an Office 2011 issue or Mavericks issue?

Any help is greatly appreciated.
My current status says that everything is running smoothly - including Outlook.  When I sign in I'm told that Outlook is not responding.  Why is this?
