Also, before you log in, look at the address bar of your browser to make sure you are on the right site to log in. (i.e. make sure your address bar says https://www.hotmail.com and not something like http:// 123abc. randomurl.com/ www.hotmail.com/). A lot of phishers/hackers have been using the tactic of making a page look exactly like your log on page to trick you into typing your password.If in doubt, type in the base URL yourself (i.e. http://www.hotmail.com) in the browser.
Hotmail technical support phone number is(NNN) NNN-NNNN but I will forewarn you. Unless you are a Hotmail Plus (paid service) member, you will most likely not be able to get any support over the phone.The problem with free e-mail services is that they rely on security question/answer combinations for verification. If you forget these and/or your account is hacked and a hacker changes the info, you have no way to verify your account. With paid e-mail services, you can easily verify your identity by verifying your billing information.
In the future, you must remember that no email service provider will ever ask you for username/password XXXXX any personal information (address, birthdate, etc.).
In any case, I would suggest to take the security measures suggested in the future to prevent a hacker from getting into your account.
