Thunderbird gemenskapsforum

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

Yesterday, Oct 6, at 3:20 pm, tbird was unable to download messages from my att server. The error message is "The certificate for inbound.att.net does not come from a trusted source". Nothing that I know of has changed when I look at the account settings.

Do I need to contact Att/Yahoo? If so, how can I describe what to tell them, as I have no knowledge of certificates and how they work (or don't work).

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

Windows 11, Dell laptop, Thunderbird Meadow 153.4.0, yahoo mail configured as pop3 (i like to keep messages on my laptop). I was having trouble with mail getting "stuck" on downloading the past week or two, sporadically. It would load maybe 13 of 90, or 4 of 64, or whatever, then I'd get a "Connection to server timed out" message. I went online to the yahoo mail site to look for some offensive email that was trying to load and delete it; deleted about 50 of the messages that would've been sent to Thunderbird, then tried again. Did this a few times. Today it started where it wouldn't even load 1 of 34, or 1 of 60, or 1 of 96 as the day went on, would just time out on trying to load the first one.

Tried changing to IMAP temporarily, didn't help. Switched back. Didn't help. (Restarting each time I'd change this). Finally resorted to deleting the account (and all of my folders and filters! argghhh!) and re-adding it. Let Thunderbird automatically configure it for pop3. I did change the setting to not have it delete the messages on the yahoo mail server once loaded into Thunderbird.

Seemed to help, and it immediately tried to download the 3800+ messages that I've saved on the yahoo mail server. Only got to 1900, then stopped and timed out.

When I ask it to download new messages, it's back to the same thing - tries loading 1 of now 2007 or something, and can't get past 1. Times out.

Notice the version number above; it was much older, and I've since updated it 4 times to bring it up to where it is now where no additional updates are available at the moment. So as much as I'd like to blame it on an update, I hadn't had any automatic updates for a long time, so it wasn't that, and getting the updates now hasn't helped either.

Any suggestions?

I've read that I can create several Thunderbird profiles and load my desired Profile to startup and use the Profile Manager to switch profiles. I'm guessing that I can only load one profile into Thunderbird at a time (?).

And if I wanted to check emails from another profile I'd have to close or switch or somehow unload the current profile(?).

It would seem to me if it were possible to load more than one profile at a time, then if two profiles had the exact same mailbox account, it would cause problems(?).

Appreciate any input from those with experience in this.

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

Bonjour,

Il semblerait que mon compte Thunderbird soit piraté. Tous les messages que je reçois sont précédés de la mention "[hotmailerrr_bot] Security Alert: " En dessous apparait un écran noir sur lequel est écrit: "This mail was moved to your cloud lounge" suivi d'un texte faisant la promotion d'un "Premium Cloud". Le message original ne peut pas être lu et si il y a une pièce jointe, elle est éliminée.

Ce problème est-il connu ? Y a-t-il une solution ?

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!

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.twc.com timed out. Try again.

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 !
