Change in Windows Live Messenger
 

Today I got this instant message when I log into mymsn messenger account:

Windows Live(TM) Messenger Service Staff (messenger@microsoft.com) says:
Important service announcement: As part of a recent system enhancement, we need you to change your e-mail address to continue signing in to the Windows Live(TM) Messenger Service.

To ensure that your access is not blocked and to learn more, go to Help and Support

I'm just curious if it's legit or if it's a virus or something before changing my e-mail adress or sign in on their website...

the website seem a legit microsoft link but I have some doubt that they would contact me directly by instant messaging.

It's legit.
