Outlook 2013 keeps asking me password and would not let me setup corporate email account

I am using Office 2013 with Outlook 2013.  Outlook works fine with personal hotmail and live.com accounts.  HOwever, when I try to setup my corporate account hosted on Azure, the outlook keeps asking me password and would not let me setup an account.  I checked my Security Profile on the other email account.  There are no options available to set "Anonymous Authentication".  Any suggestions?

Thanks.
