I am moving from a win7 pc to a win11 pc. I have exported from my win7 pc fine and get a zip file of 6.6gig. I moved it to the win11 pc, where I have installed Thunderbird.

On the win11 pc I go to tools, import and it chose the import all option and press next. On the next screen there is a live button at the bottom that says next but when I press it I get nothing.

Any ideas most welcome, thanks in advance.

Hi I am having problems signing into or adding my tpg account email address through both outlook and thunderbird. My address and passwords are correct and I have used the settings in both email programs as listed by the messaging company. The error message I am getting is that on thunder bird it cannot find the settings for my emaill account and on outlook it cant find the settings. I have had ongoing issues with my tpg account, this one is a pop3, since the messaging co took over the emails when tpg moved them to there. Issues are that i get very sporadic emails ie one week working the next nothing for long periods of time. I can successfully add gmail accounts to thunderbird and outlook without problems but the tpg one is my issue. I can get tpg emails through the gmail app on my phone with pop 3 settings but nothing on thunderbird. I have contacted the messaging co for help but other than settings they cannot help and suggested coming to thunderbird for help. I prefer to use thunderbird as my email program to have everything on one would be great again. Can anyone offer advice or assistance I would greatfully appreciate it

Today I have experienced a problem downloading new messages, bulk, trash or anything else in my mail server into thunderbird. it requires my primary password and then my regular password. I just set up my primary password so I understand why it is asking for that, but I don't understand why it is also asking for my regular password before I can get access to the mail server that I am using. the regular password was set up on 6/17/24 and until today it was working fine.

I just installed Thunderbird on Linux Mint (version 22.2), when I launch the application it automatically logs into my email account on my Internet access provider. I do not want that. I want the way the old version started up: it opened my local folders on my local drive, listed previously down-loaded mail and on the left panel it listed the folders on my main (current) email account followed my the list of my other email accounts/names. The top menu let me (among other actions) select to download email to the local email directory. I do not want Thunderbird to automatically log onto my web account or sync my local directory to the online email account. When I want to read my email I want to select to download the mail from the server. When I want to access the online account I log onto it through my web host's cpanel tool.

My local hard drive has a thunderbird directory (in my home directly) from the previous Thunderbird version. It contains a subdirector labeled Mail, which contains a directory list of my email addresses, in addition to one labeled Local Folders. There is another subdirectory labeled Mail.sbd.

Is there a way the new version can be set up similar to the old version. The installed Thunderbird version is 140.9.0esr (64-bit)

Thunderbird 148.0b3 (64-Bit) for Linux (Ubuntu 25.10) E2E encryption is "on" with OpenPGP and a key for this account

How to verify the signature a incoming message with a OpenPGP signature?

I am getting the message that a part of the message might be signed. If I click on the button "open and display" there is a new window with the plain text of the whole message but the signature is not verified. What's wrong?

Thunderbird causes my machine to 'hang' from time to time, often for up to a second and usually a number of times in quick succession on each ocasion. Sometimes this happens frequently - say every 5 or 10 minutes - sometimes only after an hour or more since the past occurrance. My machine hangs completely - nothing will work, mouse, keyboard, sound, other apps etc. If I happen to be typing (into any app - including Thunderbird - when this happens, input ceases, the cursor freezes and - if the problem persists for a second or two, Windows reports "[app] is not responding" I cannot be certain, but I believe the problem occurs whilst messages are being retrieved.

This is a very serious problem as it means that I can never leave TB running as the problems it causes are not acceptable. This means I cannot deal with incoming messages without periodically re-starting TB - which is an utter PIA.

I am running Win 11 Professional on a 2-year old machine with 64 Gb of memory. I have run TB in Troubleshoot mode, I have confirmed that the problem occurs regardless or whatever other apps are running (or none) and I have proven conclusively that no other app causes any kind of similar problem.

Looking forward yto hearing if others have had the same issue and what can be done about it.

The other day previews of messages quit working in Local Folders>Inbox. New messages will show the preview, but not any of the older messages. The preview area is just blank. I drew an arrow to the preview area.

"Could not connect to server mail.atmc.net; the connection was refused" message after the installation of version 149.0. I've verified my server settings & turned off the firewall setting & it still won't connect. It worked find before 149.0 installation.

PDF file attachments were working fine and now they don't.

I get no error message, but nothing happens when it's set to open in Acrobat. I can view the file in "Preview in Thunderbird" and the file isn't corrupted as I can save to disk and then open in Acrobat.

I tried restarting TB in troubleshoot mode with add-ons disabled, but that did not solve.

Thanks for help!

Hi folks. Suddenly I am having a problem with my e-mail account. I was working with T’bird this morning without any problems. Then I went to open my Firefox browser and I got a message that it wanted to upgrade to the latest version, which I did.

Now suddenly T’bird isn’t working. I got the message “ Enter credentials for (me) on smtp.gmail.com”. It has given me a Sign in page. My e-mail address was populated. Clicked on Next and got a message from Google “400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know”

I haven’t made any changes to T’bird. My smtp is still the same. I have just looked at my Gmail on my iPad and the only thing I notice is on the menu list there is a link to ‘upgrade’ - I am not risking that yet!

Any suggestions?

I installed Thunderbird 149.0 on Linux Mint 22.2 and I can't figure out if it's a release or a beta. On the downloads page, the "Release" section lists 148.0.1. The "Beta" section lists 149.0b4. The "Help - About Thunderbird Beta" window says "Release notes." I'm confused: what are these?

I recently transferred to a new Win 11 system. I copied the profiles over and all my address book and settings are working. I have found that my calendars are not. I have three sub-calendars attached to my Home calendar, one was downloaded "USHolidays" and is working, the other two I created and are grayed out. The hover message says they are "momentarily not available." How do I fix this so they appear?

I encountered the following problem while using Thunderbird 140.8.1esr (64-bit): While moving an email from the "Inbox" folder to an archived folder named "2026", I noticed that the archived folder had disappeared! All my searches for a solution have been unsuccessful. Do you have any suggestions? Sincerely.

Bonjour, Les mails n'arrivent plus automatiquement dans ma boite mils et quand ils arrivent ils ne s'ouvrent pas (ou alors 2 jours après...). Message : le certificat pour imap.gmail.com.993 ne provient pas d'une source sûre ! La fenêtre "Ajout d'une exception de sécurité" s'ouvre et rien ne fonctionne si je clique sur "obtenir le certificat" ou "confirmer l'exception de sécurité"....J'ai tout testé sur cette fenêtre... Je ne suis pas du tout informaticien... Pouvez-vous m'aider rapidement ? Merci. TAMINIAU Yvan yvan.taminiau@gmail.com

The user who found she could not run the new version was the user who installed the update. She returned to the previous version (which runs OK). As before the update, server access was via Pop. However her Sent and Local Folders did not appear at all on return to the earlier version and her Inbox now contained only a few recent emails from this year and emails from several earlier years was missing. She set up a second account using Imap in order to be able to retrieve all her incoming mail from the Virgin server but is still without sent mail and her local folders.

Is there any way to retrieve the missing data and to combine the IMap and Pop accounts into one?

Message sent has red texts (all containing an hyperlink). When vizualized in Thunderbird they all appear in blue. When vizualized in Gmail they appear in red! Texts written in red in Thunderbird messages still appear in black in draft's message!

I’ve tried all versions of Thunderbird on my 2020 M1 Mac, and even though I log in correctly, it doesn’t load emails from my account. I used to use Thunderbird normally because I needed it, but I haven’t used it for two months, and now I see that it doesn’t work when I try to connect to my email. It connects to my email normally, but the problem is that when I click on “Inbox,” there's nothing there, and when I click “Fetch Mail” to try loading it again, a message pops up at the bottom saying everything is fine, but in the end, I still don't have those emails. What kind of error is this?
