Article in English: Go to https://www.hotmail.com/ in your computer's web browser. Since Hotmail has been merged with Microsoft Outlook, this will redirect you to the Microsoft Outlook login page.  If doing this opens your Outlook inbox, you're already logged into your account. If your inbox opens to a different person's account, sign out by clicking the profile icon in the top-right corner of the screen and then clicking Sign out in the resulting drop-down menu. It's in the middle of the page. In the "Email, phone, or Skype" text box, type in the email address that you use for your Hotmail account. If you haven't logged into your Hotmail account in over 270 days (or within 10 days of creating the account), it will be deleted and you'll need to make a new account. It's below the text box. Type your account's password into the "Password" text box. If you don't know your password, you'll need to reset your password before proceeding. This is below the "Password" text box. As long as your account's login information is correct, this will open your inbox.
