I have a Hotmail email address and I'm using Windows Live Mail(12) under Windows 7. When replying to an email received in Windows Live Mail the "to:" box has the recipients email address and to the right of this there is a "From" field with the email address I've set up as a "reply address"(not my hotmail address). 

However when I respond to an email the return address always shows the hotmail address and not the email I've entered as the "reply to" address. I've tried Options, email Accounts, My email(default account), Properties, and set the Reply Address to the email account I wish to use as the reply to email. As noted above, this email name shows up in the "From" field when I respond to an email, but isn't there when the email response is received.
