I have an outlook.com email address, call it '*** Email address is removed for privacy ***'. I have this set as my primary. I have an alias, call it '*** Email address is removed for privacy ***'. Using Windows LIve Mail in Windows 7. When I go to send an email, I click to use addr2. But when it sends it the recipient shows it coming from addr1. When I do a reply to an incoming email, I also click the addr2 to send from. The recipient ends up getting 2 copies of the email. 

What good is an alias if the reciepent can see the primary? And why does it send it twice?

Thanks for the help,

Jim
