You must know your existing password to password protect your Outlook express.. If you know your password open outlook express go to "tools" then go to "accounts" double click on the mail account you want to password protect.. When the "properties" box opens go to the "servers" tab .. There you will see fields for your username and password.. just delete the password out of the password field and uncheck the box for "Remember Password" then just click "apply" and "ok" .. after you have done that everytime you open Outlook express it will ask you for your password.. If you father knows your password, you may have to contact your mail provider and get a new one..
