I closed Thunderbird by the X in the upper corner and my Icon disappeared off the tool bar so I tried again and the Icon was no longer in the trash bin, so I re set up and none of my old emails/folders are there and it downloaded 338 emails off the web server. My address are all gone....HELP

I am not receiving email sent from a company I do business with. I have Thunderbird.

How do I find my White list and black List to make sure it is on the White list and not on the Black List?

How do I get my email to accept it? Thank You

Hi. How can I know the correct format for Thunderbird Message Summary File (.msf)? I want to use exported backups emails y I'd like to know how to get every .eml from the .msfs generated by Thunderbird.

Bonjour, Thunderbird/ Windows 10 home /64bits 1 Depuis 2025/03/15 Envoi de mail impossible (réception OK) 2 J'effectue 2025/03/17 une restauration de Windows au 2025/03/12, date du dernier message envoyé sans problème. 3 La restauration dure plus de 6 heures ! mais j'ai un pop up Microsoft qui confirme la bonne exécution. 4 Je vérifie le fonctionnement général : Internet OK, profil Thunderbird OK, Points de restauration antérieurs au 2025/03/17 disparus; compte tenu de la durée exceptionnellement longue de la restauration je pense que windows a dû procéder à quelques réparations..il semble d'ailleurs un peu plus "agile". 5 J'effectue une double sauvegarde de mes données (profil TDB inclus), au cas où... 6 Je démarre Thunderbird , ECHEC !; message "Couldnot load XPCOM".

Je propose de désinstaller TDB puis de le réinstaller; qu'en pensez vous ?

MERCI d'avance

I want to get rid of the spam and archive folders, to free up real estate. I can specify that I don't want anything archived, but that doesn't get rid of the archive folders. I can undo the default adaptive spam filtering and set up my own "delete" filters, but I don't know how to remove the spam folders from my edresses. Are there ways to do this? I prefer the older design, though I understand that some users want those folders.

I am having issues adding att email to Thunderbird. I input my email account info and it comes back as a good account. Then I hit continue and after a few minutes it states the username or password is incorrect. I even changed the protocol from POP3 to IMAP and it won't let me.

Thunderbird has pretty much disappeared from my iMac, and I cannot find a way to solve this problem. I've restarted Thurnderbird multiple times and restarted the iMac. It came out of nowhere, and I do not know what to do. I've attached a screenshot with the screen that pops up when I open Thunderbird. None of the dropdown menus work, and I cannot access my years of email. Help!

As of yesterday my Thunderbird account vanished, screen asking to set up an account. I am too old to be an IT expert, and I need detailed step by step guidance how to restore that account, full of Inbox emails and folders/subfolders. If it matters (depending on requirements?), my address is @verizon.net - which is pop3 but I have no problem opening the same emails on different devices, as if it were imap (verizon taken over by aol). Pain in the neck, hope to get help.

I am trying to follow instructions to upload my calendar to Thunderbird and I thought I had done so, but when I click 'continue', nothing happens. I am NOT computer literate, so if anyone replies to this issue, please do so as if you wrote a chapter in ".............. For Idiots". Thank you.

I haven't used my Win 11 laptop in a while. I started it up and let Thunderbird run. It had several months of emails to download, but has now stopped at early March. I asked it to continue and get a message "Unable to write email to mailbox. ....." I know there is plenty of space on the harddisk. I cleared out a lot of the junk emails from earlier months and emptied the trash. Rebooted. Updated to latest version 128.8.1esr. Still same error message.

Hi, I am working on behalf of my dad to figure out what's going on with his Thunderbird client and trying to understand if it's a client issue, or an issue with his email address.

The e-mail address used belongs to The Messaging Company (as they have bought out iiNet/AAPT). There are issues where my dad is logged out constantly and has to retype his password, and sometimes is unable to send or receive mail. I have updated server in-going and out-going according to The Messaging Company's suggestion. I've attached screenshots.

Let me know what else I can do to troubleshoot if this is Thunderbird client or issues with the email service.

Hello Firstly, thank you very much for this great product. Secondly, I prefer to use Thunderbird as a Flatpak on my openSUSE install and have been hearing a lot about version 136. Can you please create a Flatpak version for "The official monthly release. This release is intended for users who want all available new features and bug fixes on a monthly basis.", so that we can get updated to versions such as 136 sooner rather than later? Cheers Pieter

When Tbird first began it was easy to see which folders were Imap and which were local. That distinction disappeared a while back and I still had all my imap folders but no indication of which were which. When I want to access them the popup menu did show "gmail" (since that is my email domain) and the imap folders there. But when I go to create a new folder it does not show up in the imap list even though I want it to be an imap folder.

How do I create/manage an imap folder in the current Tbird?

Number 1: I have filters that work on new messages that come in but I still have email in my inbox that the filter is not moving to the designated folder as defined in the filter. Is this due to some setting? I use Thunderbird for multiple gmail accounts. Need help because I have a huge inbox and it needs managed into multiple folders and I can't seem to get it to work. It worked one time in the past but I am not sure why it doesn't now.  ???

Number 2: Does the retention policy for a folder actually send a delete instruction to the server? I want to know how I can do that so I am actually deleting messages at the server as well. What all info do you need?

Hello all:

For the last few months, I've been having some issues with frequent lockups while accounts update. I'm now having issues with indexing, and being able to search and find messages. According to the activity screen, indexing freezes around 97% on the Inbox of my main gmail account (~17,800 messages total in that inbox, indexing stops around 17,300 and hangs).

Version: 128.8.1esr OS: Windows 10 Accounts: 4 all IMAP (2 gmail) Largest inbox: about 17k messages

Troubleshooting done: 1. Repaired folders 2. Rebuilt global Index 3. Removed All mail from sync 4. Excluded antivirus (Windows Defender)

Is there any way to find the email is causing the lockup? Any other suggestions?

Hi, we have a Windows 11 machine running 'New Outlook'. We have a new machine, also with Windows 11, but we want to move to Thunderbird on the new machine. Grateful for some advice on the best approach.

Should we migrate from New Outlook to Thunderbird on the old machine, then take a TB export (if that's possible) and move that to the new machine?

Thanks very much for any help to get this right first time!

When the Reminder window pops open with a reminder from my Calendar, I can neither snooze or dismiss the reminder. The only way to remove the reminder window is to click the x to actually close the window. This behaviour appears to have started at a recent update.

I am presently running Thunderbird 128.8.0esr in Linux Mint 21.1

I have not been receiving all incoming messages. they are not in my spam. It shows up that I have read them to others. My assistant is now checking my email and he sees the messages, but I don't seem to have them anywhere. I am getting some messages so it is not universal. It has happened with several urls. What is possibly wrong and how do I fix?

thanks for the help!
