Office365 Shared Calendar won't open in Outlook 2013

Trying to setup Microsoft Outlook 2013 and connecting to a shared calendar from your Office 365 account, you get the error: We can’t complete this because we can’t contact the server right now.

If you click the check box next to the shared calendar, you get the error.  If you right-click and add the shared calendar manually, and then click on the calendar that wasn’t working, it should work again.  Then just delete the other duplicated calendar.    I have two Windows 7 computers and a Windows 8 Pro computer that all have the same problem and have been fixed using the above suggestion.
