How do I report to Microsoft phishing e-mail proporting to be from the Outlook staff?

I have multiple email addresses including some gmail addresses.  Just recently (about the last month) whenever I send email from my default msn address it is sent out with a gmail return address.  I cannot find a way to correct this.  Even when I delete the gmail account from Windows Live Mail it still appears on sent messages.  

 

Someone is faking my email address and sending out spam which appears to be coming from my business email.  My emails to hotmail and msn  usersare now being blocked as follows:

This is a system generated message. Please DO NOT REPLY.

Your message was not delivered for the following reason:

Your message was not delivered because the return address was refused.

The return address was "<*** Email address is removed for privacy ***>"

Kind regards.
