Outlook.com custom domains to make a return?

Microsoft is Testing a Premium Version of Outlook.com

Paul Thurrott has the news as always via Mary Jo Foley. Pretty interesting as far as I’m concerned. I never understood why they didn’t make this part of the Office 365 Home subscription.

Even though it’s possible use your domain email with Outlook.com today, it would be pretty nifty for my family if they made the functionality a bit better. We have two domains and it would make a lot of sense if we could use them with Outlook.com, especially after the move to the Office365 infrastructure.
