Everyone with Outlook online has the SAME problem. I have been Have an Outlook email acct and have been dealing with the newsletter@ spoammers for months. Can't create any rules to block them because every email has a different domain name. Don't have that problem with Yahoo, so why can't MS block these emails. Maybe they are getting paid for these messages??????
