Yes, I think many people are in the same boat. I have been getting the same message on my two laptops and using all my web browsers (chrome, firefox and IE). I then tried to access my hotmail account on my smartphone via chrome and it worked. The 'url' I saw in the address line is the
https://dub002.mail.live/.... I guess this means that the 'url' is genuine, but what I cannot understand is why all the web browsers are 'shouting foul'. Something must be happening at the hotmail web server.
Can someone who knows more than us help?
