Thunderbird Community Forum

None of your "topics" addresses my issue at all. Where is your user manual? I'm trying to figure out how your "retention" works. Also how to get a message filter to run on a specific folder daily.

Thanks, Saroj Gilbert

If I have a password to sign into my Thunderbird emails, where do I find it. I haven't gotten this requirement in the past so where might I find it now and/or stop those messages?

Hello. Something strange happens in my emails. I read and/or delete an email and then at the bottom of any saved emails, the following shows up: no "from", no "subject" and no "recipient. It only shows 12/31/1969 5:00 pm. It is almost impossible to delete it. If I am lucky, it might finally disappear after closing Thunderbird and starting it again, several times. Becoming very much a nuisance. Thank you.

Suddenly Thunderbird takes a long time to download even a few (10-20) emails from Gmail and then it freezes on an email and as I click on different emails only the original one shows on the bottom half of the screen, even if I change to a different folder/email account. Also it will not close when I hit the X in the upper right corner.

If I click on one of the other apps, such as Calendar it goes to calendar but when I go back to email it still shows that same frozen email.

I tried clicking on the three bars (hamburger) to find the Thunderbird version and nothing happens.

I have restarted the computer but that has not helped.

This is an add on to the previous portion that I wrote yesterday. Today nothing shows in the portion where I usually view the message after I've clicked on it. Also the options in the tool bar such as File, Edit, View etc. do not respond to a click after the first time I have attempted to look at a message.

I am considering uninstalling and reinstalling. If I do that will it find all my emails and folders etc. again? There are a few emails that I am quite desperate to access that I have put in folders.

I'd really appreciate any help I can get on this as some important work is being delayed until I can access those emails.

Thanks for any assistance!

Using a new, clean install of Xubuntu 26.04, with thunderbird 140.10.2esr 64 bit, ubuntu snap build 1.0. In settings: play a sound when new message arrives, no sound is heard. When clicking "play" to test the sound, there is no sound. Also, if "use the following sound file" is checked, there is no sound when "play" is clicked. (I have tried various .wav and .mp3 files.) I have installed pipewire-alsa, but that didn't help. Any ideas?

the default font for writing texts is too small for me to easily read. Yet when I send the message the text size too large, How do I control these font sizes independently

I had TB on my desktop for years and finally got it also synced to my phone. Then with a failure with Windows 11 had to wipe clean the desktop and start over. Cannot reinstall TB. I obviously have the correct e-mail and password as I was able to log into Mozilla and submit this question. I believe it is a problem with my user name and what is on my phone setup does not work with my desktop reinstallation.

I have two email accounts (one is imap, one is pop3) in my older version of Thunderbird. They have both worked normally until last week. The pop3 account continues functioning normally, but now when I select (in Thunderbird) the imap account, the mouse cursor starts showing the hourglass and the bottom status bar reads "loading message" . I've closed and restarted Thunderbird, but this doesn't make any difference. The imap account is stuck on "loading message" and doesn't download anything. I also checked my imap email account on the ISP's website, there is new email there waiting to be downloaded,. What can I do to troubleshoot this?

ps...a few weeks before this problem surfaced, I had all my email (inThunderbird) disappear, so I renamed the prefs.js file and that fixed the problem. My email worked normally after that, until this current problem occured.

At the start of last week Thunderbird started to be very laggy to the point it is almost unusable.

It was after the update to version 151. Running on MacOS Sequoia

I have tried a number of remedies to try and resolve the issue:

• Compacting mail folders
• Repairing mailboxes
• Clearing the cache
• Rebuilding the search index
• Restarting in trouble shooting mode (this caused Thunderbird to hang)
• I also tried installing the daily build release to see if the issue was resolved

None of the actions above solved the problem. I would very much appreciate any help or experience others have had.

From my local folder of emails in Thunderbird, I am able to extract to .CSV and see fields in Excel. While date and time and sender and receiver and subject fields work successfully I don't see the email body coming through. How do I achieve this please?

I managed to append switch values to get the Time field included as part of my extract but the email bogy, or even a truncated part of it eludes me. I understand that some of my email body fields are substantial but currently my repeated exports show nothing. Formats other than CSV would be welcome if they can solve my problem.

I've been using Thunderbird for years but suddenly as of yesterday it's stopped receiving messages. First it told me my password was incorrect. Ever since then when I try to click "Get Messages," it simply has no response at all. Nothing happens. I went into my Thunderbird password settings, and upon seeing that the incoming-message password had for some reason reverted to an old, obsolete password, I corrected it and saved the correct one. I've checked several times and the passwords are correctly saved now. But this did not fix the problem. When I click "Get Messages," nothing happens. My Thunderbird is connected to my Earthlink account, which is working fine. When I go into Earthlink, I am able to send and receive messages as normal. So the problem is not with Earthlink but with Thunderbird.

I have had to replace my laptop and am trying to set up my new one with an existing outlook account on the new device.

It is a Windows 11 device.

I have used the exact server settings etc from my old lap top for the outlook account but get a variety of error messages.

I have explored the use of the Account Hub and also switched that off/on. Same situation.

I attach five screen captured images so far. The first is the version of TB. The second is the window that appears when the account tries to connect and thirdly the small pop up that appears bottom right hand corner of laptop. The remaining two show the server settings and that they passed the connection test.

Other email accounts (gmail & yahoo) have both been set up on the new device and work well.

The account worked on the old laptop and continues to do so. I have set up the outlook account with, to the best of my knowledge, the same settings. The old lap top was a windows 10 device. The new laptop does not have a third party antivirus on it.

I am baffled as to what is happening and what I should do next. Any advice would be great.

Please inform me how I can mark senders in Thunderbird as not spam or is there a list of secure senders so their mails will not go to spam folder?

Best regards Magnus Arnason

Hello I am having difficulty in sending message for 2 of my email addresses through Hostinger. My ither accounts through Hostinger works fine. See pic attached for the error message. Please help and advice. Thank you

I have had to buy a new desktop to get Windows 11.

I have installed Thunderbird, which I have used for many years, on the new computer. This version threads the incoming emails. I really hate my emails being threaded, it completely confuses me and prevents me doing what I have to do. I have not had this problem ever before. I have searched all the settings and not found any that will stop threading. Because the effect of threading seem permanent I now need all my emails reloaded to get rid of the effects threading.

I uninstalled Thunderbird and reinstalled hoping I could get a fresh start. I got the same old problem back again.

How can I get a version of Thunderbird that does not thread any of my emails ever?

And can I get all my existing emails re loaded?

May 25 2026. A few days ago, Thunderbird upgraded me to Release 151.0. I can no longer send or receive emails.

My wife has been upgraded to ESR 140.11.Oesr, and she has no problems.

I do not want to go through the tests of removing virus guard etc to try to make 151.0 work, so I would like to move to ESR 140.11, but cannot find online how to do that?

Please help.

Whenever i send a message , it is saved to the 'inbox' previously it would be saved "sent mail". I have verified that TB is configured to save to sent mail but the msg is saved anyway to inbox.

Can some one explain how to get back to saving sent messages to sent mail folder.

In all honesty I find it frustrating to keep moving msgs manually.
