Cannot Access Outlook Calendar

I cannot access my Microsoft Outlook Calendar.  I use Internet Explorer as my browser.  When attempting to access calendar, was instructed to update one of the following browsers for best performance: Internet Explorer, Mozilla Firefox, Google Chrome, Safari.  No other options, including skipping the update or a "no thanks" were available, so I updated Internet Explorer.  Same page comes up when I try to access my calendar.  Please help ASAP!
