I used ImportExportTools NG to export messages from one profile and import to another.

I tried to export only selected messages from my one of my local folders (it seemed an option, but IET NG is not intuitive).

Whatever, the import process has created a sub-folder in the local folder of the same name, and there is a huge redundancy (duplication) resulting.

My question: how can I merge the sub-folder into the parent, when dragging and dropping is not allowed?

Group contacts have been established and the group is listed in the Address page. An email is prepared and the group name is inserted in the bcc slot. An x appears to the left of the group name. The Send button is grayed out and the email can't be sent. What is the problem?

I have around 2000 emails in TB but it is not syncing to my gmail account (only 1000 synched). How do I refresh/continue the synch? It stopped after emails from year 2018 but there should be emails there from year 2013. Thanks so much.

Thunderbird is not synchronizing with Mailfence. My other email accounts (Outlook, Gmail) work fine. TB connects to them, downloads message headers and displays the number of messages correctly. With Mailfence, the messages stop at "connected to imap.mailfence.com" and stalls there. The message disappears after a few seconds and nothing else happens. This happened this morning when I first launched TB. I then got an update to 128.11.1. No change. I did receive the Windows Update 2025-06 Cumulative Update sometime overnight prior to launching TB.

Hello guys: In MANY YEARS of using Thunderbird, my Incoming messages have started collected in Trash INSTEAD of in the 'Inbox' Folder ALWAYS set in 'Inbox' Folder set as the default: I have spent a lot of times searching for the cause of this malfunction but I can't find to find the cause and the way how to resolve this malfunction. Can anyone provide an effective help to correct this problem please - many thanks, Tony H.

I have had an ongoing problem with Thunderbird being unable to log into the various mail servers that I use. I've tried repeatedly to solve this problem and have been able to cure it in the past by clearing the cache, but it recurs over and over again. I cannot keep wasting my time like this. I'm an independent contractor and I need to be able to use my e-mail client consistently. I've got work to do! This morning, it's suddenly decided that it cannot log into any of the three services that I use.

Is there a lasting solution to this problem? If not, please tell me and I'll move on peacefully, but please don't keep me chasing my tail for something that cannot be fixed.

I have been using Thunderbird to access my centurylink.net email for years. Now, Thunderbird does not recognize my email credentials. it asks for my password but will not accept my password when I enter it.

I have mail in my calendar. semenovvaa@gmail.com there is a reminder in the calendar. As a task. I can't delete it. Server error. It is not available on the gmail server.

I don't like threaded conversations view. I turned it off so my inbox doesn't show it any more, but search results do and I find it impossible to find what I need. Is it possible to turn off ALL of those threading features across the entire program? Thanks

Bonjour / Good day,

The e-mail display notification at the bottom-right of the screen was displayed with my r.-pi4 but not anymore with my r.-pi5; can someone help please?

Thank you for your time and I am available for any clarification.

Hi! I'm trying to set Thunderbird as the operating system default under Win 11. I tried to follow Mozilla's instructions: 1. Open the Settings application by pressing and releasing the Windows Start button, then clicking the gear icon. 2. Click the Apps icon, then click Default Apps in the list. 3. Click the icon under the heading Email to show your choices. 4. Select Thunderbird. The trouble is that at n. 3 there is no choice. There is only 'OutlookAccounts' and this item cannot be deleted or replaced. Can you help? All the best, Robifiori

As everyone using Thunderbird knows, TB folders are displayed in a column down the left side. Four of those folders are named "New Folder With Items" (three with numbers appended to the name). Those folders are empty, and I have no idea how they got there in the first place. I've tried deleting them but they always remain as before. I've attached a screenshot of those folders.

This is not a "serious" problem, just an annoying one. Any ideas how to actually delete those folders?

Hi there, I'm experiencing an issue with the Microsoft Teams add-on in Thunderbird, specifically when using it with multiple Microsoft Exchange accounts.

Issue Description:

Previously, I was able to select between accounts using the Teams icon in the toolbar without any problems. However, after switching operating systems, the behavior has changed:

• When I hover over the Teams icon in the toolbar, the account selection menu appears as expected.
• As soon as I move the mouse to select an account from the menu, the menu disappears immediately before I can click anything.
• I've made sure that the mouse doesn't leave the icon or jump erratically, but the menu still vanishes every time.

This only started happening after I changed my OS. On my previous setup, the add-on worked fine.

Fixes Attempted:

• Removed and re-added the Exchange Accounts
• Reinstalled the Owl for Exchange add-on
• Fully uninstalled and reinstalled Thunderbird, including manually deleting the profile data folder
• Disabled hardware acceleration

So far, nothing has resolved the issue, and I haven’t found any other reports of this specific behavior online.

The attached image shows the account selection menu when hovering over the teams add-on, but as soon as the mouse moves over to the menu it disappears.

System and Application Details:

• Thunderbird Version: 139.0.1 (64-bit)
• Operating System: Kubuntu 25.04
• Desktop Environment: KDE Plasma 6.3.4
• Display Manager: X11
• Kernel Version: 6.14.0-15-generic (64-bit)

Any suggestions or workarounds would be greatly appreciated.

Move Thunderbird data to a new computer

I have the complete Thunderbird folder with 15 years of POP mail.

Install Thunderbird on new PC and overwrite the complete folder?

will be the same version of thunderbird.

Guten Tag, ich arbeite mit Thunderbird auf Linux Mint. Jeweils in den aktuellsten Versionen: Linux Mint 22.1 Cinnamon Thunderbird 128.11.0esr (64-Bit)

Auf meinem bisherigen Rechner begann Thunderbird mit dem letzten Upgrade von Linux Mint langsamer zu laufen. Da ich mir nicht anders zu helfen wusste, habe ich in einen neuen Computer investiert. Obwohl der Rechner jetzt deutlich performanter sein sollte, hängt Thunderbird mindestens genauso wie vorher. Zum Teil ruft Thunderbird auf dem neuen Rechner auch keine neuen E-Mails mehr ab. Ein Neustart korrigiert das zwar wieder, aber beim nächsten Start kann es dann wieder genauso sein.

Alles, was man in den Foren findet, um Thunderbird schneller zu machen, habe ich erledigt. Cache gelöscht, im abgesicherten Modus gestartet (da ist Thunderbird genauso langsam). Auch verschieben von Nachrichten in Archivordner brachte keine wirkliche Besserung.

Ich nutze Thunderbird für 7 Kalender (zum Teil lokal) und 10 E-Mail-Adressen bei unterschiedlichen Anbietern.

Als Add-on habe ich DKIM Verifyer installiert und aktiv.

Ehrlich gesagt, bin ich inzwischen ziemlich verzweifelt, was das Thema angeht. Witzigerweise lassen sich die Entwicklerwerkzeuge nicht aufrufen. Keine Ahnung, ob das vielleicht ein Indiz für den Fehler sein könnte.

Hat jemand eine Idee? Oder noch Fragen?

Herzlichen Dank.

Telstra are changing me to fibre to my home (currently copper to home). In the process they have removed Thunderbird and introduced Telstra web mail which I do not want. But, I do not know have to re-install Thunderbird on my desktop. I need some help as my knowledge is more in keeping with 1940's to 1970's technology. Hope you can help Bob

In the past month or two I have been dealing with a constantly recurring issue with Thunderbird getting my emails. Login to server pop.windstream.net with username ----- failed, and then it gives me the option to retry, enter new password, or cancel. 99% of the time, when I hit retry, my email downloads just fine. But I have multiple email accounts that I have to go through the same song and dance on every time I try to download my messages. Sometimes one or more of my email addresses will check and download ok... sometimes all of them will... sometimes none of them will. But choosing the retry option usually yields me good results so it doesn't appear that I have something in my settings that is wrong?? And usually if I shut down of Thunderbird and a restart of it, all email addresses will down;load perfectly the first time I try.

I wonder if it doesn't correlate with a Thunderbird update? I keep hoping that the issue will be resolved as quickly as it came through another update or something but it's been long enough to really start driving me crazy now so can you help me? What is going on with the normally smoothe and agreeable Thunderbird on my very same computer using the very same email addresses all of a sudden?
