From Outlook.com, I click on the settings icon then 'More mail settings' then 'Your email accounts'. I see in the 'Outlook aliases' box my yahoo.com email address with a 'Send only' label next to it.  But when I go to manage aliases under 'Email address for notifications' page, my yahoo account is not shown. Can someone tell me how I can delete the yahoo footprint from the oulook.com account?  Thank you.
