récent utilisateur de thunderbird, je voudrais ajouter un dossier "COMMERCIAL" qui soit en mesure d'accepter les mails. pour l'instant, lorsque je crée un tel dossier il est considéré comme dossier personnel et il reste vide. Que faire ? Merci de votre réponse jpc.moneyron@free.fr

Hey, everyone!

I'm having a problem with my Google calendar on on of my Macs.

O have an M1 Mac Mini and I can access all of my calendars through that system. However, I also have a 2013 MacBook Air running Big Sur 11.17.10 and I can only access two out of my four calendars via Thunderbird 128.14.0esr on that machine.

The four calendars I have subscribed to are my personal calendar, US Holidays, Stardates (because I'm a Trek fan) and Phases of the Moon. On my MacBook, I can only access or view my personal and US Holidays calendars. The other two can't be found by Provider for Google Calendar.

Anyone know why this might be and how I ca fix it? Seems silly that an Provider wouldn't be able to access these calendars since the same version functions on both TB 128 and TB 140.

Thanks!

I am shifting over to TB from Windows Live Mail. I have installed TB Ver 115.16.2 on 7 computers successfully (Win 7, 10 and 11) over the past year. But on one Win 7 computer TB will not save the password. Usually TB asks for the Password during set-up. But here it asked for it in a pop-up box. Yes, I entered the correct password. Yes, I said "save with Password manager." But here it keeps asking for it, over and over. At one point TB connected to the POP download server, just long enough to download all the incoming emails, but then quit connecting. It won't connect to the SMTP server. The port numbers for POP and SMTP are correct and the security settings are correct. I've done a lot of web searching. Most sites say that profile files logins.json and key4.db may be corrupted. I disabled them (by renaming) and copied those two files from another computer on which the same Thunderbird version works properly on the same mail server. Same thing - TB still keeps asking for the POP server password. I just deleted TB (uninstalled, and deleted all the appdata directories, and verified there were no lingering registry keys using a list shown on Spiceworks). I'll next reinstall, but don't have much confidence that it will work. Thanks.

thunderbird 140.8.1 will not run unless restart of mac mini ios15.7.4 sequoia. only runs once then will not run email again.

Can I back up to a previous version that did run or is there an issue?

Menu: Message>attachment>delete all

When delete all attachments for a message, when delete all attachments, auto move to the next message.

This behavior is annoying, usually I first delete all attachments and then reply but message position is in the next message.

This behavior is for example for version 140.7.1esr and 140.8.1esr.

102.15.1 work fine.

Thunderbird has stopped receiving messages from @embarqmail (Sept/25) and @gmail (Mar/26) stating the password is incorrect. The passwords are correct as I can still access these accounts online. I have repeatedly updated the passwords through the popup message, but my emails are still not delivered or sent. Lucille

I just wonder why all mails suddenly seem to be totally disappeared. Without any warning. Althoug there should be 20 mails (which figure has only been creasing for the time being/already for hours. :( Also all ready models/musters seem to be deleted. So I can't add my usual signature as easy as usuaylly:

Heli Mäki [edited] FINLAND tel. [edited] < [edited] @gmail.com>

I have Version 140.8.0esr | Released February 24, 2026, for Linux Mint (up to date)

I have a CardDAV address book on a Nextcloud instance that i want to sync to Thunderbird.

When i open Address Book and the clikc on " Create a new address book" the Account Hub modal window opens. None of the 4 options (including Add Remote Address Book" do anything, i.e. I can click as much as I like but nothing happens.

Hi

When Thunderbird is started maximized it overlap taskbar if is set to hide and taskbar won't show until Thunderbird is minimized and maximized. Another way is to press the Win key two times. Then the hided taskbar can be shown/use. The same thing happens to Firefox. Only when is first started. Then if Firefox is minimized and maximized, press Win key two times, press F11 two times then the hided taskbar show/hide normal.

It is a setting that can be changed to start Thunderbird and Firefox in full screen and do not overlap hided taskbar?

I would like an apple (icloud) account to thunderbird, but it doesn't work the automated way. I changes password and made sure that account data and password fit. Anyway I got an error message and wasn't able to connect. I had no issues with outlook and the apple account, so I'm wondereing what I need to adjust or add. I want to finally switch all my accounts and systems to open source and getting them connected is my first step. Any help would be appreciated. - Thanks in advance!

Hello, so I have Thunderbird installed on 2 Windows 11 PC's both are updated and operating with all updates! On my 1st (main) PC which I use 98% of the time Thunderbird has been running perfectly with IMAP and Oath2.

Last night on the 2nd PC I rarely use I opened Thunderbird and it started to download messages for awhile and all my 2026 up until OCT 2025 disappeared?

I logged into Yahoo Mail from a browser and yup all gone?

I sent a deleted by accident request to YAHOO and today all my mail had returned when I checked on my 1st (main) PC.

I started the 2nd PC and all was good, till it started downloaded messages again? And POOF right back to square one?

What's happening? Should I confirm that IMAP and OATH2 are enabled on that PC before I do something else? I've sent another DELETED request to Yahoo and at this point I'm thinking to just REMOVE Thunderbird all together on the 2nd PC.

After downloading and running installer (Thunderbird setup 148.0) from Thunderbird website, Thunderbird opened as usual, showing my three email accounts. The 2 accounts I use for almost everything are both Yahoo accounts (yahoo.co.uk and rocketmail.com). But.. neither of these accounts will work without a yahoo sign-in pop which is pre-filled with an account name (example graphic attachment : thunderbird01red.jpg). 1 example shown but the same thing happens for both yahoo accounts.

The 'Next' button, which I assume will ask for password, does nothing.

I have attempted login via webmail. I enter account name, am asked for password and Yahoo insists on sending me a verification code - to the other yahoo account (the yahoo.co.uk account), which I cannot access! I then attempt to login to the other account to access my pass code and the same thing happens in reverse, telling me that a verification code will be sent to the first account.

Via Thunderbird, which has for years done all this automatically behind the scenes, I can get absolutely nowhere. Via webmail, I am in an 'impossibility loop'. I have cleared cache for each account.

Why won't Thunderbird allow automatic account login, as has been the case since the year dot. These are the 2 accounts around which my entire life is ordered - can somebody please help.

I have some more email accounts with Hotmail and Outlook but there is popping an error just after the popup where it asks for permissions to connect Thunderbird to my account, and I say Yes and also receive the email that some new apps have connected to my accounts, but Thunderbird just at that step instead of Finish it displays that error message like asking again for Username and Password and even if I fill there the correct details it doesn't go further. Something is unclear at that step, because I also tried removing the passkey from the respective account Page at outlook.com and also the 2FA but the same.

Can you help me?

Thanks

Mam problem, pierwsze parę kont dodanych do Thunderbird działa poprawnie i nie ma z nimi problemu. Natomiast pojawił się problem z kolejymi pocztami -nie widzę na nich połowy folderów, albo w sumie żadnych, ani wiadomości wysłanych, ani roboczych. Znowu na innej poczcie w odebranych, nie widzę nadawców - tylko własnego maila. Próbowałam na nowo zainstalować te poczty, jednak nie przynosi to zamierzonych efektów, albo wręcz jest jeszcze gorzej.

I've tried setting up Thunderbird archiving according to the documentation to save archived messages locally, and in the same hierarchy they had when I archived them. That is, if I have:

INBOX

   Box1
   Box2

... etc. then archiving would create a parallel structure in Local Folders

However, this isn't working.

I select "Keep message archives in Other (Archives on Local Folders).

For "Archive Options" I select "A single folder", "Keep existing folder structure of archived messages" and "Recreate inbox folder".

However, when I archive something, Thunderbird just creates a folder "2026" (this year) and puts the message in there.

Why are my settings NOT working?

no matter what i enter in settings, any time i minimize thunderbird in win 11 to tray, and then click on its tray icon to reopen it, it opens at this odd sizing every time. i always put it fullscreen again, and minimize, then go to open it again, and there it is, at the odd size again. no other program does this in my two machines. just thunderbird, and i have never set this size and placement, it just seems 'forced' every time, making me have to resize it every time i open it from tray.

I like to default to having threading on. It used to be that when I opened my Inbox, every email thread was closed/collapsed. Now they're open (started somewhat recently).

I can get numerous separate emails where each one can generate lots of responses, meaning they threads get long, sometimes within a few minutes or hours. Having them closed by default (rather than open or unthreaded) makes it to see each individual email chain and other interspersed single emails.

I tried google searching; also tried threaded and grouped by sort (with the default sort set to thread), and it doesn't seem to help. Any help would be appreciated!

J'ai déjà un mail gmx , "andre.et@gmx.fr" est-ce cette adresse qui est crypter ?
