There are requirements to transfer the subject of the sent message to e-mail from the form "Forgot password" on The login page. You must also translate the error messages that appear when you send the message.
Subject Email: "One time password for resetting operator password"
Also it is impossible to translate the message:
Invalid username - if username empty
Error occured while sending email. Please contact your system administrator. - if default outbount email connection status Failure.
Any thoughts how to find the Field Value of the message or where they are installed?
This is an older post that hasn't had any activity since February of earlier this year. If you don't hear back from the original user, I would recommend creating a brand new post. If you want, you can also tag @Krithiga_GCS after you answer her questions from the comment above.
