Thunderbird ver 140.0 (64-bit) on Windows 11.

Brand new, fresh installation of Thunderbird. - Added a GMail account. That worked. - I tried to add an account with my personal domain. I enter my name, the email account, and Thunderbird gets stuck in an unending loop looking up the configuration. - Other email clients have successfully looked up the config and did the setup without a problem. - The email account is handled via IONOS.com servers. - If you gave me a manual setup option I could handle it but there is none; TB goes straight into trying to handle it itself.

Any ideas?

TY, Frank

New Laptop. Windows 11. Bitdefender protection. Installed Thunderbird and a first gmail account on new Laptop, all OK. Attempting to instal a second, different gmail account I get the following 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." 

No problem having installing the 2nd gmail account in my internet browser on new laptop after continued failures to instal in Thunderbird. NB I have both gmail accounts previously (and easily) installed and working in Thunderbird on PC, old laptop, phone. Issue does not make sense. Does anyone have a solution please.

I'm using thunderbird for gmail account, and I struggle to mark some events notification as completed when they are deleted using gmail interface. They keep on poping up but when I hit `Dismiss` it gives me this error: ``` Status Code: 2147500037, The request cannot be processed.

Server Replied with 400 If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view. ```

I don't want to make my calendar read-only because I'm still gonna use it but I can't remove these annoying pop-ups because of the error. Please help what can I do

I recently purchased a new computer and want to setup Thunderbird to use my ATT Yahoo mail account. I went through the automatic process and got an "incorrect information" message. I tried Yahoo's instructions and they don't match what shows up in the account setup in Thunderbird. I am stuck and need some step by step instructions to set this up. I found nothing in the help section. Thanks.

My checking account was just billed for another month of Thunderbird. To the best of my ability, I have already requested that my subscription be cancelled. I use Tuta. Please cancel my subscription/billing. Many Thanks, Ron Axelson [edited email from community support forum] @tuta.com

I have a domain that has email accounts. It was established a long time ago. I want to add a new email address for that domain. The MX records point at google. I try to create a new google account but can not because it wants to verify the new address, which gmail does not recognize. The automatic account setup fails when google wants to verify the address. So, I can't add a google account email because it doesn't exist. Suggestions please,

Bonjour, Par erreur j'ai effacé toutes les données contenues sur le support de mémoire de mon ordinateur et depuis je suis incapable d'accéder à mon compte thunderbird et à ma messagerie. Je n'ai pas de sauvegarde. Est-ce mon mot de passe qui n'est pas reconnu ou est-ce le serveur ? Merci de m'apporter votre aide. D. Anseaume / 06 72 39 09 68

Hi, Win 10 Pro new installation. Dell Optiplex MBR type Bios.

I had saved a recent profile to an external drive in its own name (i.e. not the profiles folder)

After the new Win 10 installation, I downloaded a new copy of Thunderbird.

I then copied the saved profile into the new Profiles folder, selected it in Choose user profile and started Thunderbird.

Thunderbird opened but not with the saved (8+ Gb) profile, just one new email account and asking for passwords to other email accounts I used before, and no folders.

I went back into the profiles folder and renamed all other profiles "OLDxxx999, but still the same one new email account when I opened Thunderbird.

I desperately need the saved email folders - I don't mind loading all the email accounts again, just need my court case history folders.

How can I force Thunderbird to use the saved profile, or can I identify and individually load in the saved local folders?

Thank you for any guidance towards a solution.

I just upgraded (reluctantly) to Win11 on my desktop, and my POP Thunderbird account did not survive the upgrade. I had to switch over to a new IMAP Thunderbird, losing all of my POP folders (which are still on my disk). Just not, apparently, accessible.

Anyone have info on how to re-access or somehow get them into my IMAP install?

Hi, A few weeks ago, my desktop PC had to be returned to the manufacturer for repair, so I had to move my email to my laptop. I have 9 email accounts (3x yahoo, 3 x Microsoft, 2 x GMX and a Gmail). I used to train adults how to use a computer or laptop (basic training) so had addresses for different providers, so I was familiar with anything they could throw at me! Some don't get a lot of use now, but I like to keep them, for the odd occasion. All the accounts loaded sweetly at the time, some requiring 2FA, but none needing any App Passwords. A week ago My laptop had a catastrophic problem requiring me to restore to factory defaults. Since then, I have been reinstalling all the programs/apps to get it something like it was before the disaster occurred. Obviously, as part of the process, I had to reinstall Thunderbird. However, I have not been able to get any of the accounts to get set up on Thunderbird. The settings are found in the database and passed as okay, but I've been getting messages like: "Unable to login at server. Probably wrong configuration, username or password." I know the settings are correct because I have double-checked them very carefully, and I also use Bitwarden to ensure the Username and Password are correct. Initially I had wondered whether it was just one account that was a problem, and had tried other (alternative and approved) port and security settings but got a "Thunderbird failed to find the settings for your email account" message. I am puzzled, because about 3 weeks ago everything went in so easily, and I completed all nine accounts one after the other in probably less than half an hour, and now I can't complete any. I'm obviously playing with the idea of trying another email program, but also liked the calendar in Thunderbird. I'll attach some screen prints below. I also use Nord VPN, but for a fortnight it didn't matter whether Nord VPN was on or off, Thunderbird was brilliant. Today I was wondering whether that was having an effect, so I switched on Split Tunnelling, and applied Thunderbird, but it made no difference. So my next thought was whether as part of the Factory reset of the Laptop, not all the registry entries for Thunderbird had been cleared, or that there was some files somewhere that had escaped the purge and Thunderbird was still pointing to them. However, that didn't make sense, because I had Uninstalled Thunderbird with BC Uninstaller and deleted entries found after uninstallation, before I reinstalled it. So what can I do other than find some other email product, which seems unlikely at present! Kind regards.

I have added Gmail and another account successfully to Thunderbird, but when attempting to add Icloud Mail it fails and says to check passwords, etc. Using the same credentials I can log into the icloud website successfully, so it is not my userid or password.

I tried the method discussed here for the gmail issues but that made no difference.

Adding Icloud mail is the last account I need.

Any ideas or anyone else with same issue? Platform is Linux.

Hi, I am trying to use Filelink to send a large file. I selected WebDAV and am trying to log in there on Mozilla's Composition screen. Under Private URL it wants me to enter my username and password. I entered my email address and password but error message says account not properly configured, What am i supposed to do?

years ago my Verizon.net email account was taken over by AOL. I can access that acct from the AOL web site. I would prefer adding it to my current Thunderbird account. I have tried various configurations, but none succeed. Suggestions appreciated.

I periodically backup my Thunderbird AppData information: C:/Users/<me>/AppData/Roaming/Thunderbird

I believe I installed Thunderbird from the MS Store.

On one device (MS Surface Go, Windows 11), this directory does not seem to exist. I have hidden folders visible, and several folders show up under AppData\Roaming, but not Thunderbird. I tried using %APPDATA%\Thunderbird, which works on my other devices, but the result is "not found".

I created a local folder ("save") and then used "properties" to display its location:

mailbox///C:/Users/<me>/AppData/Roaming/Thunderbird/Profiles/pv771buo.default-release/Mail/Local Folders/Save

When I put this into the file explorer and hit return I get told there is no app to open this 'mailbox' link, and I should look for one on the MS store. When I remove the mailbox/// it gives me the "not found" dialog.

I used the help->troubleshooting dialog to "Open Folder" under the Profile Folder entry, and got a "Location is not available" dialog. The dialog cited the same folder path as given above.

Where is the Thunderbird App Data stored? How do I access it????

Problem:

You remove an account like Google from Thunderbird, but Thunderbird continues to repeatedly show a pop-up to log into that account (in my case Google). I've noticed it even freezes the Thunderbird UI on startup.

I seem to be paying £20 per month as a donation. I am not saying I want to change this, but how can I review/cancel/change the donation? I appear to have been paying since April 2024 via *Hidden for privacy*@gmail.com

I thought Thunderbird was free to use. It's asking me to donate and I can't access my current emails from my account. If this is free than why on earth do I HAVE to donate to get access to my emails. That is not right. Please help me.

Thank you Malcolm
