'''I am trying to set up an existing Thunderbird email account on a new hardrive''' I can't remember my password and it does not give me the option to reset password. It wants to send the reset verification code to the email I cannot access without my password I've downloaded Thunderbird email pinned to my startup. When I open it up the 1st dialog box wants full name, email address, and password. I can't go any further to get in to my existing Thunderbird email account.
