I have successfully used the Outlook (Office 2011 for Mac) on my old MacBook.

I just got a new MacBook Pro (OSX 10.11) and installed the office program on the new computer.  The other programs work.  I can put in the email address, password, etc. and then open Outlook, but every time I do that and click on an email, I just see the little circle going around and around and around, and nothing else ever happens. 

I have deleted that email account and re-added it several times, and it still doesn't work.  This is my husband's business email account, and we really need access to it.  I'd really appreciate help.  Thank you.
