I have read the numerous complaints from other hotmail users that someone else has their same email address. Despite your assurances that this is impossible, it definitely is happening and it happened to me.  I started receiving order confirmations for another person with the same email address, and even confirmed with one of the senders that this is the email address they've been using to send email to this person who has the same name as me.  I have updated my security info but this doesn't seem to be an intentional attempt to hack my account, but instead a mixup within Microsoft. Please advise.
