Hello, since recently I am no longer able to use my Google Calendars in Thunderbird. Environment: - Thunderbird 153.4.0esr, 64-bit - Windows11 - Google Calendar / CalDAV - No “Provider for Google Calendar” add-on installed Problem: My Google calendars previously worked normally in Thunderbird. Recently Thunderbird started showing that the calendar was temporarily unavailable, and attempts to modify events resulted in: MODIFICATION_FAILED I therefore removed all Google calendars from Thunderbird and tried to add them again. When adding the calendar using: https://calendar.google.com Thunderbird opens the Google OAuth login. I can log in successfully with the correct Google account and complete the authentication process. However, afterwards Thunderbird reports: “The entered credentials were rejected. Please check the settings above.” I have already tried the following several times: - removed all stored Google / OAuth credentials from Thunderbird - restarted Thunderbird - verified that cookies are enabled - verified that no VPN is active - tested the Google Calendar successfully in the browser - tried the direct CalDAV endpoint at apidata.googleusercontent.com - confirmed that the “Provider for Google Calendar” extension is not installed The Google account and Calendar itself work normally in the browser. The issue therefore appears to be related to Thunderbird’s Google Calendar OAuth / CalDAV authentication. Could you please confirm whether this is a known issue in Thunderbird 153.4.0esr and whether there is a workaround or fix planned? Thank you.

Hello, i use Thunderbird on two desktop-pc and one mobile phone for my e-mail account. Since two days it is not possible anymore to place attachments on one of the desktop pc. The other devices work correctly. What can I do? Best regards, Andreas

Ich kann seit heute Vormittag (9.10.) die Funktion "Anhänge" bei thunderbird nicht mehr öffnen, also keine Anhänge mehr hinzufügen. Wer kann mir helfen? Auch mit Str. + Umschalt +A funktioniert es nicht. Vielen Dank, Gesche

Also to find the suggested file mail.compose.attach.dir I can not find to remove this file. This was suggested to resolve the problem that I can not add an attachment in Thunderbird since 3 days

This morning, my email Inbox is empty. I use Thunderbird for four email accounts, and three of them are fine, but the fourth one has an empty Inbox this morning. I didn't (intentionally, anyway) move the emails anywhere, and they do appear to be in the All Mail folder, so I didn't lose them entirely. But I keep my emails mostly in my Inbox and they aren't there anymore.

Any ideas what happened to make them disappear and how I can get them back to the Inbox?

Thanks!

This seems to have occurred in the last month or so.

Whenever I click on a message in the folders pane, the message is not displayed correctly in any of the three layout views but, if I am offered to display in a browser, it does! Also, if I select 'Edit as a new message' it displays correctly, as also do iPhone and iPads. The screenshot shows the problem?

Any ideas, anyone?

Was hat sich in der Einstellung Thunderbird verändert weil ich keine Bilder und Daten mehr als Anhang versenden kann. Anhänge werden nicht angenommen. Holly Produkte Helmut Pilz

Greetings,

I've lost the ability to receive e-mail, Suddenly Thunderbird just quits on me with no warning. Apparently I can still send mail but cannot receive. This is the second time this has happened to me in as many months. How do I fix it? How do I prevent it?

Thanx

How can I get rid of that horrible bug of Thunderbird prompting me for my login credentials. Already tried the following: re-adding my Email account, reinstalling Thunderbird from scratch. Nothing has worked.

Le clic sur joindre ou Ctrl+Maj+A n'a aucun effet par contre joindre page Web ouvre une fenêtre, pour résoudre: J'ai redémarré le PC, idem J'ai fait une mise à jour de Thunderbird, idem. Je sèche...

I use a personal computer, and can access my email two ways: 1) By typing "att.net" into my browser and choosing email." 2) By booting up PC, typing PIN, then a 16-digit alpha password generated by ATT. Two days ago this function stopped working. Q: What can I do to again access my email via the ATT account? I called AT&T yesterday, and human advised me it was a Thunderbird problem.

And I don't know how to "...find my version in Thunderbird App menu as requested below.

Thanks!/rose

Hello, I hope you are doing well.

I have asked a number of questions since starting with Thunderbird for Windows 11 a few months ago.

Is there a user manual somewhere? If not, it appears many of us would need one.

Please let us know where to find it or, if there isn't one yet, please create it.

Thank you in advance!

Since the Thunderbird update of 30 Sept the ability to attached files to my emails has 'vanished'. I press the attach 'button' but there is no response. Never had this as a problem before. I am running Windows 11 home version. Help!

I recently set up Thunderbird for Windows as a troubleshooting step for my Yahoo Mail account which has been generating an incessant number of authentication pop-ups in Microsoft Outlook (Classic) for Windows. I had been using New Outlook for many months before switching to Classic Outlook a couple of weeks ago. With New Outlook, there had been no authentication issues nor pop-ups appearing. I have been using the OAuth authentication, not app passwords, in all cases.

Setup within Thunderbird was relatively easy and the OAuth authentication went through without issues. The account has synchronized and seems to be continuing to do so as I read, delete, and send messages.

However, when I went in to the Activity Manager, I'm seeing a number of errors, appearing every 10-15 minutes or so. They read as follows:

• Alert from account xxx@yahoo.com: AUTHENTICATE Server error - Please try again later

• The current operation on 'Inbox' did not succeed. The mail server for account xxx@yahoo.com responded: UID FETCH completed.

• The current operation on 'Inbox' did not succeed. The mail server for account xxx@yahoo.com responded: p.

Can anyone help me understand what they mean? It would help me stabilize Thunderbird and might give some clues as to what is happening in Outlook Classic for me. It would seem some have authentication issues with Yahoo on different platforms while the service works perfectly fine for others. I would like to move away from Yahoo as I find it finicky with a number of its features, but I'm a long-term user (25+ years) and don't see that being a practical solution at the moment.

Thanks!

Bonjour,

Je sollicite votre aide concernant la restauration de dossiers de messagerie dans Thunderbird.

Contexte : Le problème est survenu suite à un glisser-déposer par erreur d'un dossier (et ses sous-dossiers) depuis ma boîte nominative (IMAP) vers une boîte mail générique partagée. Le dossier a disparu de l'interface Thunderbird et du Webmail, mais la arborescence physique existe toujours sur mon disque.

Détails techniques :

Dans Paramètres des comptes > Dossiers locaux, le Répertoire local pointe sur : C:\Users\sojanati\messagerie\Mail

Dans ce répertoire, je retrouve la structure sous forme de dossiers .sbd (comme INBOX.sbd) ainsi que des fichiers d'index .msf.

Cependant, les sous-dossiers et leur contenu n'apparaissent pas dans l'interface Thunderbird sous Dossiers locaux.

Comment puis-je forcer Thunderbird à réindexer ces dossiers .sbd ou récupérer les messages associés ?

Merci d'avance pour votre aide !
