When I first set up my Hotmail account using email address *** Email address is removed for privacy ***, I was surprised to find that I immediately received a lot of spam. This has continued after upgrading from Hotmail to Outlook. I have now received emails addressed to *** Email address is removed for privacy *** clearly intended for someone else. Why has this happened, and should I create a new name (alias)? How can I block all emails to my existing account when I have created the alias?.
