I-Thunderbird Community Forum

I have been using T-bird for years successfully until lately. We have multiple email addresses in Comcast and Gmail, but lately our passwords that we have been using and know are correct because they are written on paper and Keypass, are being changed somehow so that they will no longer work. When we look at the saved passwords in Thunderbird we see some have been changed on a certain date that we did not do, and the password listed now must be about 200 characters long. Then when we go to change the password, it may be listed as changed. Then when we try to send a message with that email address, we get an error message saying, for example, smtp.googlemail.com and a wrong username/address completely. I can find no way to correct the username email in any settings in Thunderbird. I have searched the Thunderbird HELP files many times, but am unable to find any of this addressed anywhere. After trying to fix these problems for most of 3 days now, I have get rid of Thunderbird for an email client that works correctly!!!

With 03.04.2026 they began to notice that the attached emails in eml format (the attached emails have attached documents, mostly pdf) sent from yandex mail stopped opening. Everything used to open well. Eml also does not save to disk. If you send the same files via Gmail, everything opens. Program version 150.0.1

I have been using Thunderbird for 10+years and was able to set up Gmail accounts without any problem. Currently, there are 3 Gmail accounts configured under Thunderbird and those all are working fine. I needed to add one more GMAIL account, everything seems to go through OK, but near the end, it fails with an error message: "Unable to login at the server. Probably wrong configuration, username or password."

I also installed Thunderbird on MAC and repeated the same steps to configure GAMIL account and got the same error message.

The same errors occur if I configure APP PASSWORD in Gmail and then try to configure GAMIL account in Thunderbird using APP PASSWORD. Still got the same error message.

HELP PLEASE

Hi I have a hotmail account registered to my Thunderbird account, I receive mail. OK but it won't send mail comes up with error "unable to connect". Followed by:- (Should be a screenshot but it wont load?)

which says "Sending message failed The message could not be sent connection to server SMTP timed out."

This is a new occurrence not experienced before?

If I go to webmail it will send OK?

I have daily tasks that I dismiss every morning. When I open the Tasks tab, all the dismissed tasks are still there. Is there a delete the completed tasks so they don't clutter the task list? The attached image shows my list of dismissed task, all in red.

I use Thunderbird and received a message about an update which I allowed. I went to another app and when I checked Thunderbird all of my data is gone. The only folder Mozilla Thunderbird folder reads: tobedeleted. It is empty. All of the data is gone. Is there a way to retrieve it? PD - [edited from public] @gmail.com.
