I  have an e-mail account within gmail. The account has a ".biz" at the end but I sign in on the gmail log in page with user name being the full email address, including the ".biz" at the end of the address. How can I set this account up in Outlook?

So far it won't accept the address xxx.biz And it won't accept the address xxx.biz.gmail.

What version of Outlook? What exactly happens when you try to set it up in Outlook? You'd use alias@domain.biz as the address and email username. Use the server name gmail tells you to use.  

I have the same problem, but he corporate gmail account looks like a traditional email domain.  Not sure what settings are required to allow it to import into Outlook.com
