Microsoft also has this cool thing where if someone fails to get into your account too many times, your account can get locked and you are asked to reset your password. For a working password.
Even after changing my password, I couldn't login to my email on my phone, so I just gave up. I only use that email for a handful of things anyway.
Their enterprise account system (active directory or whatever it's called) also has an awesome bug where if you accidentally reload the page during password reset, the link will no longer be valid, but your old password will already be invalidated. So you won't be able to log in at all untill IT staff manually changes your password.
