Scenario:

Small Business with Office365, all using MacBook Pro

Outlook 2011 works just fine with O365 account

Cannot add second email account using IMAP to Outlook

IMAP account settings are correct and run in Mac Mail, iPad, iPhone, Android Nexus, Windows Outlook 2013, Windows Outlook 2010 and Postbox

IMAP also runs just fine in Outlook 2011 on a different MacBook Pro

IMAP account is from GoDaddy and they can't figure this out

Can anyone explain to me how to add this IMAP account to Outlook 2011 when Office 365 is present? 

If my client moves their account off of Office 365 to GoDaddy or Google, this would be a non-issue, but there are other factors prevent us from doing that.  I've spent an extraordinary amount of time on this, which is why I now have this email account installed every which way (on every piece of equipment) except where it is needed.
