I received an email from a friend into my Rogers email inbox from his Hotmail account giving as the subject "Hotmail". In the text box, appeared an http address and then below it, my friend's message. When I opened the http address thinking that he wanted me to look at something, it turned out to be the access straight into MY Hotmail account right into the InBox showing all my emails etc., also access to Sent etc.

When I contacted him, he knew nothing about it and when I asked him to check his message in his Sent box, there it was, exactly as I have said. He was astounded and erased it.

What has happened here? I have erased all of my messages in my Hotmail account both sent and received and am now frightened to use it.
