Attempting to add a gmail oauth account in TB fails authentication using verified account password. (The account requires two-factor authentication using an authenticator app, but haven't tried that as a password) I have removed the account from TB, and the saved passwords for the account. I then added the account back to TB but get the same "Failed authentication" notification without any opportunity to register a new password. I can not find a cookie to remove and retry the process.

How do I stop all the messages subthreads from being populated on the message tab? For example, with I open a message with subthreads, all the trailing messages are displayed on the tab. The only way to get them off the tab is by clicking the x in every message. A real pain. I don't want this. How do I stop it?

I migrated one mac, which was intel based, to another, which is M4. It all went fine. I have the same versions of OS and Thunderbird on each, before the migration. The new machine is a 2025 Mac Studio. The old machine is a 2018 Mac Mini, 6 core Intel Core.15

On the old machine in Thunderbird, under my user, all my files are listed. On the new machine, files are not listed.

I saw a lot of information/suggestions to replace the Profile folder under: USER/Library/Thunderbird/Profiles And I copied it straight over from the old machine, with negative results.

I did notice that under profiles, it continues: m8mojurw.default-esr/Mail/Local Folders/ where there are some other goodies, some of which are "documents".

however, on the new machine, those same files are there, except they are "unix executable files"

I have migrated many times over the years and this hasn't happened.

I have done all of the suggestions I found so far, such as the Profile copy/past, reinstalled Thunderbird from scratch, looked thru comparisons of the Account Settings....

Oh, a couple more things:

If I look under my user and go to "Account settings" then "copies & folders" to looks different on the 2 machines. The old machine has: a check next to "Place a copy in" and under that a dot for "Sent folder on:" and my user name. On the new machine there is: "Place a copy in" and I cannot write into the "sent folder on" space, I can only select Choose and Account -> Local files as if the user doesn't exist (?) Thanks

I have two accounts with Thunderbird (*@talktalk.net and *@tiscali.co.uk). Each account will receive incoming emails (with or without attachments - single addressee or part of a group email). Periodically outgoing emails are blocked, with the error message 'Sending of the message failed. An error occurred while sending mail. The mail server responded: Reject for policy reason. Please check the message and try again.' Usually the issue seems to fix itself - this tome it has lasted longer than usual. Please can someone suggest a remedy? Tony

MY SYSTEM: Thunderbird 140.5.0esr running in Linux Debian Bookworm

I have created a filter from a recently received message via pop. The settings are: OK Manually Run OK Getting New Mail: Filter before Junk Classification

Match all of the following From Contains xyz.co.uk

Perform these actions: Move message to XYZ on my mailbox

Press OK

In the Message Filters window, Run selected filter(s) on: XYZ Press Run Now

There is no response, and all the messages remain in the Inbox.

I have repeated the Run Now process on an old filter (by moving the message back to the inbox), and that works fine.

The only oddity of the current message is that it is a no-reply message eg From = no-reply@xyz.co.uk

Any ideas welcome!

I have missing buttons or shortcuts in my Thunderbird. There was a refresh button and a new message button on my tool bar, they have disappeared. Is there a way to get them back? Thank you!

Hi, is there a way to get Thunderbird to move to the tray when I press the X button in the top right corner?

I've tried enabling "When Thunderbird is minimized, move it to the tray" but that just changes what the minimize button does. When I press X, Thunderbird still quits.

I've done some googling and I found this extension: https://services.addons.thunderbird.net/en-US/thunderbird/addon/minimize-on-close/

The problem with it is:

1. It doesn't seem to work with modern versions of Thunderbird
2. It lets you either minimize the window or move it to the tray, but not both (X and minimize do the same thing)

Can I get Thunderbird to close to tray only when I press X? So that the minimize button still works normally? Thanks

Comment, not a question. My now obsolete laptop ran Ubuntu 14 and its now 15 year old Thunderbird. Worked wonderfully well. My current laptop running Ubuntu 22 and Thunderbird 128.12.0 has driven me nuts since I got it. Slower than a snail loading. Confusing layout and function trying to group related messages into threads. I DO NOT LIKE IT.

I understand many of your customers might love the current Thunderbird for what they do with it. Can you somehow make available the older version of Thunderbird without all the fancy updates?

I converted my old Outlook emails in to MBOX using the Syscurve conversion software, and then moved the MBOX file into my Local Folder for Thunderbird. When I open Thunderbird it sees the file, but does not see the folders or messages inside the file. The Local Folder has the following three files in it (plus the trash, etc.): output_20251127110416.mbox 4,194,310 kb output_20251127110416.mbox.msf 2 kb output_20251127110416.msf 2 kb Thunderbird shows the output_20251127110416.mbox in the Local Folder but says no messages found when I click on it. How do I get Thunderbird to see the mbox files?

I must be doing something wrong. I am new to thunderbird, migrated from Eudora since I can't send mail with Eudora anymore.

I tried to configure Thunderbird as much as possible like Eudora, but ... it doesn't receive nor send mail. On the surface it looks fine, it seems thunderbird logs into the server, it seems it sends mail and checks for new mail, only I don't receive anything, nor send anything even though it looks it does. So what am I doing (or is going) wrong? (I can still receive mail with Eudora and today I checked and received 54 mails, none with Thunderbird)

I have a filter set up on one of my computers with Thunderbird that copies all incoming emails into a local folder. I then have a filter on the local folder to mark those messages as read (see attached), but it doesn't work. Is there something I'm doing wrong?

with some changes with a default search for passkeys, I am no longer able to use thunderbird mail as is, as after spending three hours today, I was unable to add a 2nd account that has been accessed via gmail for a long time. I am wondering what other email problems other than thunderbird might have similar features,. as thunderbird has been rendered unusable by new code/passord, passkey requirements. I was looking at spark, but their interface is not as helpful. Thoughts! RIP Thunderbird mail, a long time friends, but time to move on, alas

Bonjour, Nous avons un problème avec l'utilisation de Thunderbird. En effet la boite des messages envoyés reste vide malgré les mails envoyés. Si toutefois nous envoyons un mail depuis une autre plateforme celui-ci apparait. Pourriez vous regarder car nous avons vraiment besoin d'avoir les mails envoyés.

I would like to donate .. i really would .. but .. I use PAYPAL for donations, and when I try to donate, the first thing you do is ask questions I'm not going to answer. I have an account already .. seriously that should be enough to give you money. OR if i go to paypal, have a donation link there.

I had to install Windows 11 fresh because of multiple issues with my PC (I upgraded from 10 to 11 6 months ago). I installed Thunderbird fresh, and am trying to get it to see my existing data with is on my D drive. I browsed to the folder in Account Settings, but it's not showing up. I have years of mail and don't want to lose it.

There are too many options in the help for me to know which are actually related to my situation. I thought I was ready to do this, but am surprised at how difficult it is compared to the last time I did something similar.

Any help, even just pointing me to the right place to look for help, is appreciated!

Thanks!

Have tried so many times to transfer from old laptop to new laptop, never works. Have watch the youtube videos and followed this. Can not get it to work. Just want the emails from the old to the new laptop Thank you

Method using a transfer device On your source computer Connect a device for data transfer, either a local one such as a USB flash drive, or a remote storage drive. Click the menu button Fx57Menu, then click Help and select Troubleshooting Information. Locate the "Profile Folder" entry, then click Open Folder. Your Thunderbird profile folder will open in Windows Explorer. Close Thunderbird. From your Thunderbird profile folder in Windows Explorer, go up three levels. Right-click on the Thunderbird folder and select Copy. Right-click the device you are using to transfer your data, then select Paste. If you are using a local transfer device, remove it safely from the source computer. Note: This steps can also be used to create a backup of your Thunderbird profile folder.

On your destination computer Connect the same transfer device you have used before to copy your Thunderbird profile folder from the source computer. Right-click on the copy of the Thunderbird profile folder that you created on the transfer device, then select Copy. Open Thunderbird (Close the account setup window if it appears.) Click the menu button Fx57Menu, then click Help and select Troubleshooting Information. Locate the "Profile Folder" entry, then click Open Folder. Your Thunderbird profile folder will open in Windows Explorer. Close Thunderbird. From your Thunderbird profile folder in Windows Explorer, go up three levels. Right-click inside the folder, then select Paste. When prompted, choose to replace your current data.

I somehow changed the actual email screen (where the message to send is) and have lost the "Send" button. How do I restore it? I tried to attach a screen shot and was unable to.
