Thunderbird gemenskapsforum

I can't retrieve or send emails. says sending of password for user vnoel3@start.ca did not succeed. I hit ok and window comes up enter new password. I try but won't take new password. Are you having issues this morning? Thankyou for your time.

Hi there,

I have looked for hours on your site on how to get thunderbird sending emails, I have attached this to my outlook account and used all the correct IMAP/Port/Server settings that are displayed.

For some reason when I go to send an email, it says to me that "login to server smtp.office365.com with username ****myusername**** failed" THEN it says "Unable to authenticate outgoing server (SMTP). Please check the password & verify the 'Authentication Method' in account settings, Outgoing Server (SMTP)" I have done all the above multiple times, I have even tried other settings, and it STILL DOES NOT WORK.

I would greatly love some help with this as it is now becoming very tasking and frustrating. Please can someone help me out ASAP as I would love to start making use of Thunderbird.

Thanks - Max!

Hallo und guten Tag,

Bei der Installation von Thunderbird auf meinem PC gibt es Probleme. Leider kann Ihr Server mein Programm nicht anmelden. Die Konfiguration ist angeblich nicht korrekt. Vor einigen Jahren habe ich schon einmal mit dem E-Mail Programm Thunderbird gearbeitet. Offensichtlich sind in Ihrem Server noch die alten Daten (Passwort und Benutzername) gespeichert. Bitte löschen Sie diese und geben Sie jetzt die neuen Daten ein. Bei der jetzigen Installation handelt es sich um eine Neu-Installation auf einem anderen Computer.

Vielen Dank und freundliche Grüße

Sur mon compte paul.coudert@bbox.fr le système me demande brusquement un nouveau mot de passe. Je suis bloqué pour cette adresse. Comment retrouver un mot de passe valide ?

After I upgraded my system to Kubuntu 24.04 thunderbird started eating CPU (150+% CPU usage according to htop). Because I couldn't tell if the culprit was the new KDE or the old profile, I tried to create a new profile, blow away the KDE config, etc. I also tried downloading the latest version of thunderbird from the website. Nothing helped.

I was able to replicate this problem using the in-memory, fresh KDE.

To replicate: Create Kubuntu 24.04 install USB. Boot from this USB. When asked to install or try, select "Try Kubuntu".

Start Thunderbird.

When prompted to create an account, select cancel. Go into settings, to the bottom, and select Maildir for file storage. Quit thunderbird, and start it again. Create account (select configure manually, enter the information for imap and smtp host, STARTTLS, detect authentication. My username does not contain an @, if that makes a difference). Select "Re-test"

Try to read mail. You will quickly notice that Thunderbird is consuming > 100% CPU, and UI is non-responsive.

Restarting thunderbird does not help.

netstat -tupane shows one or two connections to my imap server port 143, but wireshark doesn't show any traffic on port 143

Not that I think it matters (since I can't get Thunderbird to start seriously downloading from the server) but I have a big ( >100G) Maildir behind my courier server.

Note that I see this problem both with the version on Kubuntu 24.04 install USB, and the latest version downloaded from the thunderbird website.

recently installed thunderbird / Mozilla on new computer but cannot send emails and get message as seen below. old computer still can send emails OK

Dear all,

While writing a new message with TB 128.5.0esr (64 bits), under windows11, the action "Insert Web link" make the TB windows freezing, and there is no way to close it out of killing TB process in the task manager.

The only way for now to send an email containing an hyperlink is to start TB in Safe Mode .

Is somenone has an idea for that issue as the functionnalitie was well working in previous TB versions .?

I have an issue where, from one day to the next, one of my employees lost the "open thread in a new tab" option. This option was available when right-clicking on a message and then selecting "open/open thread in a new tab." The option no longer works in the "inbox" folder, but it does still work in individual subfolders.

I usually display the items ordered by the date they arrived. I changed it to 'From' but now it will not change back. I select 'Date' and the 'sort by' line flashes but nothing is affected. reselecting 'Sort by' shows 'From' is still selected. How can I get out of this situation, please? Am I doing something wrong? It has worked in the past. John

Hi, I have started to use Thunderbird Mobile (Android) and it looks great. One thing I miss (or can't find) is the print option. I have it in my other apps and it works perfectly in my other apps. I can find a share option but there is no print option in that one. Am I missing something or is it just not a print option in Thunderbird Mobile yet?

Error message when trying to send a message: Sending of the message has failed. Peer's Certificate issuer is not recognised. The configuration related to smtp.message.com must be corrected. When you click on OK, it brings up another lengthy description of licenses etc.. but no result. I'm trying to send a picture but I'm not sure how. In-any case, i'm sending this for my Wife's account: erika-b@netspace.net.au

We had a long-standing conversation with The Messenger Company, but the were unable to solve the  problem.

Hi Support, A customer uses Thunderbird as their main mail platform but suddenly cannot send or receive messages. error message as follows: Sending message failed. The message could not be sent because the connection to the SMTP server timed out. Try again. we get this message directly when we click send (1ms)

Now we checked our Mail Server, connection is up also TLS to port 587 works fine but the client can not establish a connection... it worked a few days ago tho. We also tried to reinstall Thunderbird, new profiles and also tried debugging but we could not find the mistake.

Bonjour,

J'utilise 2 comptes de messagerie Gmail sur Thunderbird, et je dois toutes les semaines remettre les mots de passe google de ces comptes pour continuer à l'utiliser. Que dois-je faire pour supprimer ces demandes trop fréquentes.

Merci par avance, Hervé Serre

After Thunderbird just updated to Version 128.5.0esr today, now all my accounts are saying that the connection is refused. This is coming from three different email services that I have accounts on. I'm assuming it's not an issue with those servers as I can access them just fine with a different email client, and I didn't change any settings. Yesterday it worked, today it doesn't. Only thing that seems to have changed is Thunderbird got updated.

Some emails show a message body that's nothing but / separated groups of ASCII characters, as for example "FJ/OHS/U7R/R3A/NT4/R03/0QY/T1N/VRC/WJ3/J6E/YXK/I6K/WNA..." continued for several pages. These are generally (but I think not always) obvious spam - that one has subject "Try Semaglutide and join the millions of women losing weight fast." But not all obvious spam is shown that way.

Is this something that Thunderbird is doing, or is the gibberish the actual message? I've only bee using Thunderbird for a few months, and don't recall seeing anything like it with my previous email program (Opera). I'm using version 115.7.0 (64-bit) on OpenSUSE Linux.

I am receiving the following error message when downloading messages from AOL to Thunderbird. "The DELE command did not succeed. Error marking a message as deleted. Mail server pop.aol.com responded: Too many requests." Please could anyone help me download my messages? I have been away for a month, I have a lot of messages to download. Could that be causing the problem?
