Mr. Worry,
please relax. Your health is much more important than your email
account's security.
An expired certificate is nothing to panic about. Even MS takes time to
renew them. Just press "Yes".
As far as I am aware, MS never had a system where you were not able to
enter passwords infinitely. This is probably due to the limitations of
HTML. Ie, once a user has entered an incorrect password too many times,
the only way of recording it is with a cookie. The user could then
easily delete this and continue. I suppose you could do something fancy
with server side scripting to record the info there, but of course
simplicity is bliss.

I would presume that the two websites are the same. Microsoft tends to
buy all similar sounding domain names to all its legitimate websites.
However there is still a chance that one of them is a clone of the
other. Trawling through the source code will likely reveal subtle
differences. The clone website (if it is indeed a clone,) will likely
have some code to transmit entered passwords to a third-party. This
should stick out like a sore thumb.

Sorry to use so many cliche~s. They should be avoided like the plague.

HTH
