Hello, Thunderbird starts with "Authetication Failed" for my main account. After deleting the saved account/Password in Thunderbird it DOES NOT ask to enter a new one. It seems, Thunderbird hast still the Old informations saved, but it does NOT appear under Passwords / User Accounts in Thunderbird. How can I enter a new password in Thunderbird ? Has anybody a REGEDIT clue or any other help ? THANKS

I want to get all my emails down and saved before Yahoo starts deleting them. I asked already and got directed to the tool Importexporttool.NG which I got. Installed. Tried it. It didn't work. Something wrong on that machine. Big mess. Now I am here on a new machine: linux mint, new Thunderbird. complete with the tool. I have got two accounts with yahoo. I have one set up via IMAP and it has downloaded everything. Inbox and nearly 100 custom folders. The second one is not set up yet. Next step I think is to get all these emails, custom folders and all, into 'local folders'. Then set up the other account and do the same Then I'm done. Right now I have a hitch: can't clearly see how to do this with Importexporttoolng and certainly don't see any other way. You will appreciate that with 100 folders manual on each folder is something i want to avoid if i possibly can. We only have about three days left I think. Anyone can steer me through this?

1. How to move mail between two different Macbooks with different OSX and different versions of Thunderbirds?

How do I move my email profiles (there are several) from an old Mac to a new one, when the old Mac can't be upgraded anymore and the Thunderbird versions don't match?

Old Macbook OSX Monteray 12.7.4 can not go any higher on OSX due to hardware not being compatible Thunderbird 140.5 Oesr 64 bit - don't know if it can be updated or not, but expect not. Minimizing run time as much as I can because the fan is going nuts and I think the battery is going - gets very hot.

I copied all the different profile folders from the Old Mac to an external drive. However, I don't think I can just plop them in to the new Profiles folder on the New Mac, given the Thunderbird versions and OSX version don't match.

New Macbook OSX Sonoma 14.1 Thunderbird 153.0.2 aarch64 Not updating to Tahoe yet because then I can't use my 2019 MS Office products - need to save up to update those first

All I need is e-mail - not calendars, contacts etc., although it might be nice to to have those Thanks in advance

2. How to .pdf old emails (With attachments) Also, the profiles folder is huge (219 GB), with multiple profiles and I want to save old emails (with attachments) into .pdf and appreciate advice on what .pdf converter/file converter would be best. It doesn't have to be free. It does need to respect my privacy.

Sometimes an email I receive contains text whose right margin and text is chopped off. I thought this was because the emails were formatted for Google's gmail, but I just received an email from Thunderbird itself that is truncated this way. What's going on?

I'm enclosing a screen shot. I can also send the .eml file if that's helpful.

Na versão 153.0esr do Thunderbird, quando se clica na pasta com o botão direito do rato, o menu não apresenta a opção de adicionar pastas aos favoritos. Para além disso, quando se arrasta uma pasta para a área das Pastas favoritas do menu esquerdo, nada acontece.

I am having problems accessing my email [redacted]@hotmail.co.uk I am currently using Windows 10 on my computer.

I sent you a very detailed email the other day unfortunately I am not sure if you got it because I could not verify it because I think you sent me a code or something to the very Email I cant get access to clearly as a 68 year old man who knows nothing about modern technology things like this are not what you need I am also classed as Severely disabled with various illnesses from Diabetes and sleep apnea to Ulcerative Colitis and mental health problems.I also have CTS in both hands so trying to type this out on my phone is not ideal I am not having a go at anyone but I would have thought that with the amount of intelligent people connected to technology organisations that one of them would have thought about this type of problem and came up with a simple solution it's not rocket science if the main problem I'm having is not being able to access my email and have no other accessible other ways to confirm things to you surely a freely available freephone number from the country you live in to yourselves or if you yourselves contacted the person Directly preferably on their home phone but if not their recognised mobile number and asked them some basic security questions by firstly asking them for two step verification to their mobile (if they have one) likewise I am aware not everyone had either a home phone or a mobile (or both) because of various problems I have encountered with verification methods that are not available to me or might be but I dont know how they work then surely I cannot be the only one? under the 1998 Human Rights Acts and Protocols Article 1 Protocol 1 people like myself are meant to have protective status especially here in Britain where the 2010 Equalities Act is meant to give us added protection and certain rights all I am asking for is to speak to someone who wont talk to me using Computer Jargon and at least has some Empathy and Common Sense to help me get this Sorted I use Firefox and Mozilla because I Like what you are trying to do but if you are going to cause people like myself the exact same problems I and others like me may as well just not bother with technology because the Stress it causes me in particular is simply not worth it. Thank you for taking the time to read this Tomb and I really do hope you can help me because I have no other options left PS I cant follow written instructions if I could I would not be in the position I am in Hence the need to speak to someone and not a Robot Thank you

I recently got a notification that a Thunderbird update was available, so the update was downloaded and installed.

Next I went to my inbox to tidy it up, by deleting some items and archiving some that I wanted to keep. On looking at the 2026 archive none of the items where found.

Why has this happened and is there any FIX ?

For whatever reason after the lastest Thunderbird update Windstream is refusing the connection to Thunderbird email client. I have gone through all of the delete .msf files for all of the inboxes tried adjusting server settings to no avail on anything.

Each time I open TBird, I get a message at the bottom left of the screen telling me that TBird has deleted X number of messages. I do not want TBird to ever delete any messages. How do I turn this automatic delete function off?

In the process of changing from Windows to Linux, I have entered the details of my email account and it is fine when I press re-test, but when I press done it is not fine anymore. The email is “freeuk.com” which is still active but Freeuk itself isn’t, but the service was taken over by Claranet with a “clara.net” setting, so I imagine that may be relevant. Any help (not too technical please) would be appreciated. Thanks.

Grouping emails is awesome. Also have the preview show a bunch of compressed email info when a group is selected. However if the group contains only one email nothing is previewn. Is this a bug or a feature?

I changed my password for Greenby/Plusnet today. Now Thunderbird is unable to connect to them. The password is correct as I can enter website directly. No problems before change. Grateful for help.

Should I reinstall?

Somehow I got 2 emails: gregory@gregorysantana.com and Gregory@GregorySantana.com The lower case shows a lock blue envelope and the upper case shows a lock red envelope. I don't understand the icon meaning of the lock icon and the color coding.

Further: I use command File, sub menu Get New Messages for All Accounts.

In the lower part of the overall panel, I see new messages downloading, but the new messages don't show up in either account.

How to correct, it is important.

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

As in the subject, my computer has sound everywhere else but, despite 'play a sound' still showing as ticked in general settings, no sound happens when an e-mail arrives. And, in general settings for 'when a new message' arrives, I can hit the Play Button there and the sound happens. How do I fix this?

Environment:

Thunderbird: 153.0.2esr (64-bit) Operating system: Windows Occurs with multiple email accounts Reproduced on two different computers running the same Thunderbird version

Description:

After updating Thunderbird to version 153.0.2esr, released on 4 August 2026, emails can no longer be dragged and dropped from Thunderbird to the Windows Desktop or any folder in Windows Explorer.

The problem occurs with all tested email accounts and folders. It has been reproduced independently on two different Windows computers using the same Thunderbird version.

Saving an email manually with Ctrl+S works correctly and creates the .eml file. Normal drag-and-drop between folders in Windows Explorer also works. Only dragging an email from Thunderbird to Windows Explorer fails.

The issue also appears to affect third-party applications that use Thunderbird to create or send emails automatically.

Steps to reproduce:

Open Thunderbird 153.0.2esr on Windows. Select an email in any account or folder. Drag the email to the Desktop or another folder in Windows Explorer. Release the mouse button.

Actual result:

The email is not copied or saved to the selected Windows folder.

Expected result:

Thunderbird should export the email as an .eml file in the selected folder.

Additional information:

Ctrl+S successfully saves the same email. The issue affects every tested email account. Thunderbird extensions were disabled, but the problem remained. Thunderbird Troubleshoot Mode did not resolve the issue. Restarting Thunderbird, Windows Explorer and Windows did not resolve it. Thunderbird and Windows Explorer are not running with different elevation levels. The problem was reproduced on a second computer after installing the same Thunderbird version. No relevant error is shown in Thunderbird’s Error Console when the drag-and-drop operation fails. The issue was not present before the recent Thunderbird update.

This appears to be a regression in Thunderbird 153.0.2esr affecting email export through drag-and-drop and possibly Thunderbird’s integration with external applications.
