I have deleted contacts from the contact group mailing list but emails are continued to be sent to former email addresses on the list.  When I click on the list compostion, those addresses are not show but when an email is sent, former members of the list are being sent the message.  How do I fix that?

I am very exasperated with Microsoft for creating this problem. The company should be ashamed for putting Hotmail customers through this. As a temporary solution it seems you can go to your Group and delete the Contact. Then go to your Address Book and totally delete the Contact there as well. Then add that Contact back in your Address Book. It seems that will delete the Contact from the Group and that Contact will no longer receive email sent to the Group.
