Thunderbird Support Forum

Exported address books and lists from 115.12.1 (32 bit) on W8.1, importing to 115.11.1 (64 bit) on W11.

Importing a named list into personal address book works - but the list itself is lost; they all go into one big address book. If I choose Create a new folder they all go into that - but again I've no list name, I can't write a message to the list like I used to be able to.

I can select New Mailing List, give it a name, but now I seem to have to enter each one individually, I see no way to paste in a list.

What am I doing wrong please?

Hallo, durch eine Unachtsamkeit habe ich das Hauptpasswort (Primäres Passwort.) von Thunderbird gelöscht. Ich finde auf den Hilfeseiten keinen Hinweis wie man da Passwort zurücksetzten kann. Dadurch komme ich nicht mehr an meine Mails. Freundliche Grüße

I have a Windows 10 pc, which is current with all Microsoft and manufacturer (Lenovo) updates. Thunderbird won't run since the last update. It just gives a message saying, "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?" After several reboots, I have given up. A support forum solution from 4 years ago recommends deleting a file (global-messages-db.sqlite) at a location (C:\Users\user\AppData\Roaming\Thunderbird\Profiles\8charstring.default) that seems not to exist (hidden?) on my pc. What do you suggest? Thanks.

A new problem since July 1, 2024 Thunderbird keeps crashing on start-up when checking for new mail. HELP!! Crash ID: bp-e8be7291-7fe9-41c0-bd21-45d860240702

I have received an email from Microsoft informing me of changes to its authentification procedure. As from Sept, to continue using Thunderbird to access my outlook/hotmail accounts, I have to change the authentification method to Oauth2. The reasons and changes required are detailed here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 I have 2 problems. 1. imap-mail.outlook.com - I can change my authentification method to Oauth2. However, when I then try to access my mail via TB, I get an error stating that the server imap-mail.outlook.com does not support the authentification method! (see image) 2. Outgoing Server SMTP There is no Oauth2 option available to choose!

Can anyone help? I am using the most up to date version of Thunderbird 115.12.2 (64-bit).

have been using Thunderbird mail for about 3 years. It’s template selected the incoming and outgoing servers and ports etc..successfully. I've been connecting to Prodigy mail/ATT I had to change the battery and it doesn't work anymore. Can you help ???it checks the password until it shows an error message that the servers password or etc are wrong. I know the password is right since I can log in directly. Messages :

1- Configuration found in ISP Database

2- Checking Password (for a few minutes

3- Unable to log in at server..probably wrong configuration username or password

4 then nothing

Worked great before battery change

I received a notification from @hotmail and @live that I won't be able to receive or send mail after Sept 17th without taking action - what steps should I take when I don't have Microsoft Office 360?

We have recently moved to a new mail server. We currently have about 20 Thunderbird email clients on Windows in an office location and a macOS home machine. On all machines email is configured to use IMAP on hostname.com port 993 SSL/TLS with Normal Password and SMTP on hostname.com port 465 SSL/TLS with Normal Password.

The home machine is working 100% with no issues, it does have a much faster and lower latency internet connection than the office machines.

Many of the office machines are experiencing intermitent SMTP error messages when sending, intermitent, "unable to save mail in the Sent folder of the Inbox", messages and intermitent unable to move messages between folders.

I have checked and double checked the settings on affected machines - however, I believe a settings issue would result in nothing working, not intermitent functionality. Plus all is working fine on the home machine with the same settings (different OS, but ports and security settings all dictated by server).

With one client behaving properly, the server likwise behaving properly when addressed by the working client and the intermitent nature of the problems we are finding, I suspect we have some sort of network issue. Somthing timing out or a firewall/AV software causing a delay.

I have increased mailnews.tcptimeout on affected machines to 250 based on a forum article but this has had no effect (No idea of units here but if it is seconde then I am not supprised - the SMTP errors, when they happen are almost instantanious).

Any ideas on how to trobleshoot this problem further - The problem seems to get worse through the day, although that may just be peoples tollerance of an intermitent issue going down.

I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.

WHY is it that I can get into my email account through Thunderbird and download mail, but when I try to go into the account manually I can't? I go into the settings copy the password, then manually input it into gmail, but it says it's the wrong password? I am using MacOS 10.14.6, and Thunderbird 115.12.2 (64-bit)

Thanks.

I have TB ver 115.12.2 64 bit. It reports as being up to date. During attempting to make the changes necessary to accommodate Microsoft's Modern Authentication I reach a point where the option to select OAuth2 does not appear in the Outgoing Server SMPT settings drop down menu, see the image. How do I deal with this? Thanks for your help.

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

I was looking for an email I expected to find in my Inbox, and found that a message filter was applied to move it to another folder. I can see the filter log entry for this action.

This filter consists of 9 specific email matches ( From "is" ....); the message that was moved is NOT in this filter list.

When I moved the message back to my Inbox, it was moved again.

Any ideas on how to stop this happening? Can I even trust filters?

I recently deleted all my filters as I was not sure they were working correctly, and recreated them carefully. I currently have 10 filters, a few are one off created from a message, and none have more than 10 matching requirements.

I have attached an image of the filter at issue, and here is the filter log entry:

[7/1/2024, 9:40:07 AM] Applied filter "Bad Shopping" to message from grandrr@olypen.com - [RW] RW Potluck Tuesday July 2 at 7/1/2024, 9:19:44 AM moved message id = faecf27e13e90b655df9ff49ee14a5ec@olypen.com to imap://sjstowell1000%40gmail.com@imap.gmail.com/Good Causes & Bad Shopping

Why? Actual bug? DB problem?

I have done a custom install of TB on D:\ drive, moved Profiles folder to D:\, verified that account settings/server settings have local directory pointing to D:\ drive.

Can I delete all TB files on C:\? TB still *seems* to be using those files. I really need to free up space on C:\ - tiny drive filled with Windows OS, huge D:\ with nothing on it.

Thank you for your time and attention!

I have set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE in both Thunderbird and Betterbird.

I have created the file C:\Users\MYNAME\AppData\Roaming\Thunderbird\Profiles\r2v9k1zw.default\chrome\userChrome.css

I have successfully entered css into that file that work as expected in Thunderbird v115.12 and has for the past several versions. But I have NOT been able to do anything in that file that works with BetterBird. In fact, using the inspector, I don't see userChrome.css even being loaded! I have also tried starting the file with '@namespace html url(“http://www.w3.org/1999/xhtml”)' but that makes no difference either.

How do I get BetterBird to recognize the userChrome.css file?

I had a POP account on my desktop PC for many years. Recently I purchased my first laptop and decided to go IMAP on it, while retaining my old downloaded emails as an archive on my old desktop PC. I turned off automatically downloading emails in this desktop PC's POP instance of Thunderbird.

(The desktop PC is Windows 10, the laptop is Windows 11.)

I didn't want to transfer these old emails from my desktop PC to an IMAP server, because they weren't organized -- everything was in the Inbox. On the new laptop (and/or on the IMAP server), I am diligent in putting emails into appropriate folders.

My question is: how can I convert the desktop PC to be IMAP while yet retainomg my old email archive, so that I can access those old emails as needed on both desktop PC and laptop PC -- which will both be IMAP?

Hello,

I have been using Thunderbird for some time and it has served me well. I used it to manage my gmail accounts with encryption and so on.

Recently I have deleted one of my gmail accounts and when I launch it Thunderbird asks me to log in to that account. "Sign in to continue to Mozilla Thunderbird Email" And I am supposed to enter my email.

I have checked the account settings: the old account (let's call it old@gmail.com) is no longer there. I have also removed the outgoing SMTP server for the old account.

I do not know how to stop the app from asking me to log in to an nonexistent account.
