HI Tony.
The article you are referring to is SmarterTRACK, which is different from SmarterMail.
I see you have posts going back past 2019.
In Smarter Mail there are 3 levels of access.
1) End user account
2) Domain administrator
3) Smarter Mail administrator
If your account was the domain admin and you can not reset the password, try logging in as the SmarterMail administrator. There you can reset the passwords for any account on the server
