Hotmail Authentication Request

E mail received Supposedly from Windows Live Team asking me to authenticate Hotmail account. The wording seems slightly suspicious and makes me wonder whether the request is genuine. Threatens to close Hotmail account if no response within one month and I am somewhat hesitant to proceed at this stage.

Just wondered whether anybody else has received a similar message.

Since Outlook for Mac 2011 did a major update a month ago I have had so much trouble.  No syncing will occur. I have deleted identities, deleted all the sync preferences and finally got to the stage where I could actually set SyncServices to allow me to choose contacts, events etc to sync.  But still nothing syncs to ical or Address Book.  I have signed out of iCloud as some forums suggested this may be an issue.  I am going mad.
I really wish I had never done the update.
