How to I set up Outlook 2011 for Mac properly?  Right now I cannot send out emails.  When sending out emails, I receive this error message: "Cannot send mail.  

The SMTP server does not recognize any of the authentication methods supported by Outlook.  Try Changing the SMTP authentication options in Account settings 

or contact your network administrator.

Account name: 'Comcast Mail'

Error code: -17092"
