You can change your sign in settings such as your email address or password via the 'Signing In' section of 'Settings'.
You can access this via clicking on your username on your screen header and then selecting 'Settings'.
From here, click on the 'Signing In' tab found on the left of the screen.
This is not helpful. I need to change my email address as i cannot access the hotmail.com any longer. The change page in Settings only allows for a new password. Please advise me. I no longer receive emails and billings etc. Thank you
