Any email you receive from anyone, who says "you must update....." is a phishing scam. If you have any doubts, log off your email, then go to the site, in the email, by typing it yourself. You can then safely ask if it is legit. Never use a link to check it out. Some of them, if you were (don't) to click (don't) on it, sends you to a site made to look like the real one. Play safe everyone.
