Getting rid of 'unread mail' message

[laissez-faire]

Someone used my computer, signed into hotmail and didn't read all emails. Now when I log in it says 'Sam - One unread mail message'.

How do I reset this? It is the kind of thing that will wind me up!

I know the Microsoft TweakUI powertoy can disable the Unread Mail feature.
