Version: 102.12.0 FYI, the buttons / options that i refer to might be named slightly differently, as i'm using dutch language for my interface. '''Summary''' The enter password dialog is not showing up when sending an email over SMTP, when the password previously was added to the password manager, but has been deleted since. '''What happend''' # I've had a working account to an IMAP and SMTP server (both same subdomain, same password, diffrent ports). # the password was stored in the password manager. # the subdomain and port of the SMTP server needed to change, and i update the subdomain and port in account settings > outgoing server (SMTP) > Edit SMTP server. The new subdomain for SMTP was not known yet by the password manager. # on sending the next email through SMTP, i was prompted for the new password, with the "store in password manager" checkbox unchecked. # I entered the wrong password (LDAP instead of email) and checked "store in password manager", then continued the email send process. # this led to an error sending the email. # I checked online how to change the password and found https://smallbusiness.chron.com/reset-password-thunderbird-48064.html , which advised me to delete the password from the password manager. # I deleted the password, closed the password manager dialog and restarted thunderbird as per the previous link. # I pressed get messages without getting prompted for the SMTP server password, which is expected as the IMAP is still using the old subdomain with the stored password. # when re-sending the email that i have in my draft / concept folder, i was not prompted to enter the password for the new SMTP subdomain, even though i removed it from the password manager. # sending timed out with error about failed to send the email, because connecting to the outgoing SMTP server failed. with the added hint that perhaps the server is not available or refusing SMTP connections. However, the connection does not have a password to connect with stored, and other people are able to connect to the new SMTP subdomain and send emails. '''What have i tried''' * Troubleshooting Mode * Clear startup cache * restart thunderbird * reboot laptop I've checked https://support.mozilla.org/eu/questions/1245702, but this did not help my situation and can't find anything else that matches my issue. Can you please help me with how I can either manually add the password for the subdomain (the subdomain is no longer in the password manager), or trigger the SMTP add password dialog?
