I've used TB successfully for many years to access several Yahoo and Googlemail accounts. Windows 10. Recently the Yahoo accounts don't work so I've tried several times deleting and reloading them. This may be a red herring but the trouble seemd to start when I installed TB on a new Windows 11 laptop and failed to load the Yahoo accounts. I've tried following both Mozilla and Yahoo help articles but ultimately success is partial at best (i.e. incoming works, outgoing fails) This is the sequence I have followed

Tried app password - failed Tried normal Yahoo password - failed

Have two email accounts: Outlook and Gmail. They check and pull mail off the servers independently. I would prefer to only have to look in ONE account for my mail. I have chosen Outlook. I am having problems getting Thunderbird to push the emails in my Gmail folders to the corresponding Outlook folders. Is that because it can't be done? In settings for GMail account, under Copies and folders, I push: Sent messages > Sent on d*******1@outlook.com Archives folder > Archive on d*******1@outlook.com Drafts > Drafts folder on d*******1@outlook.com but they don't seem to be going there.

Is there a way to move messages in GMail TRASH to Outlook DELETED? As you can see, I'm not very aquainted with these things and am pretty confused. Any help appreciated.

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

I have built up a collection of more than 400 deleted emails in my 'Deleted' folder. I am sure I will not need to refer to any of them again, and I would like to finally remove them. In the past, there was a command among the various sets of commands at the top of the page, which removed all of them, after confirming that this is what I wished to do. I can no longer find this command. Please tell me where to find it. If it no longer exists, tell me how to deal with 'deleted' material.

I'm not able to log into yahoo e-mail via Linux Firefox (145.0 (64-Bit)): The error message is "We were unable to log you in. Please try again from another device." I can log in with Chrome (Linux and Windows) and Firefox (Windows). My issue is to switch from POP3 to IMAP in Thunderbird. There the same error message occurs.

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

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.
