Hello there We have read the message. We try to help Follow Up!! You write that you can no longer send outgoing messages. Try viewing your outgoing server details in your Thunderbird Software. These settings are set as they are normally set for use. After an update, some miscommunication could have arisen, resulting in a situation similar to yours. Together we can see whether this can be completed so that it works as it should again. Can you send me a screenshot of your outgoing SMTP server settings for email use? This is probably installed in your Thunderbird software on your desktop.
