Thunderbird Community Forum

I've successfully connected to a hosted Exchange server through EWS and NTLM authentication (kudos BTW). But there is a problem - often during operations against EWS I'm presented with "Login to account XXX failed" "Login to server YYY with account XXX failed". I can ignore it (cancel) and it will work for seconds or minutes but eventually reappear. Sometimes it's very frequent, sometimes is here and there. TL;DR; connection works, I can read directories and e-mails.

From looking at development tools I see these scenarios: 1. POST requests return 200 always (no messsage of course) 2. Eventually a POST would return 401. Then Thunderbird issues a GET, it returns 401 as well but response includes header WWW-Authenticate: NTLM XXXXXX. Then another GET is issued containing header "Authorization" with the value from previous response. This time it gets 200 and continues without POST requests without a dialog. 3. Sometimes there are more POST requests with 401 (I assume in parallel) before a GET is issued and then I see a dialog. Sometimes it recovers (regardless of whether I cancel or retry), sometimes gets stuck with 401 with dialog reappearing each time it tries something. This case it's similar in sense that thunderbird issues GET with 401 and WWW-Authenticate header, issues another GET with Authenticate header but still gets 401.

If I had to guess I'd say the problem happens when POST requests are issued in parallel, not sequentially. OTOH it might be a problem at the server, but it isn't very likely.

I find now that Thunderbird requires Earthlink's password each time an email is sent. Earlier it required it once a day. I am on Windows 11 using Earthlink.net for provider.

After being on the right side for decades, the Options button on the remote content box was moved to the left side. How does this improve accessibility for the average user? Is there a rational reason for doing so?

Since Thunderbird update to Snap ``` 140.12.1esr (64-Bit) Mozilla Thunderbird Snap for Ubuntu ubuntu-snap-build - 1.0 ``` opening attachments ceased to work. What does NOT work (any more):

• Move mouse over attachment → right mouse → open (nothing happens)
• Move mouse over attachment → right mouse → open with (doesn't exist)
• Move mouse over attachment → doubleclick (nothing happens)
• Settings → Attachments → There is an empty box, and in the void beneath it, floating in empty space the text (backtranslated from DE): "Add a Filelink-memory service" or "Filelink-save service" or similar. The text is dead (not clickable), same for the empty box.

AFAIR, in the good old non-snap TB version, the box had file extensions and linked applications to open them. The box / links / extensions coud be added, edited, removed. But in snap crap it's all dead...

Any hints what I am missing?

I used to open attachments from received mails (like .diff, .patch), and also used it for final inspection of own attachments while composing mails.

Sometimes, the following message opos up: /run/user/1000/doc/1d06e601/binutils-sort-text.diff konnte nicht geöffnet werden, weil die damit verknüpfte Hilfsanwendung nicht existiert. Ändern Sie die Verknüpfung in Ihren Einstellungen.

I can't find the "compose" button that used to be on the "home page" of my Thunderbird email. HELP! It shouldn't be so hard to perform a simple task but something has changed and I can't figure it out.

I am visually impaired and need to increase the font and make them clearer, but I can't find any help with that problem. I guess if you have problems seeing the page, there is nothing you can do to make it better.

I have over 200 email accounts in Thunderbird, and I am getting constant pop-up error messages that say: "Не удалось открыть индексный файл для 'Входящие на [email]'. Возможно, произошла ошибка на диске или полный путь превышает допустимую длину."

I don't need help fixing the emails themselves, but I need to permanently disable these pop-up alert windows because I will soon have over 2000 accounts and I don't want 2000 errors popping up.

I am using the latest version of Thunderbird. I have tried looking for "about:config" or the "Navigation Toolbar" to change the settings to "false", but my interface is heavily customized and I cannot find the menu or the address bar. I need a step-by-step guide on how to disable these error alerts, preferably using the Windows Registry or a configuration file if the menu is hidden.

On my PC I continue to get message about long-ago email address. I cannot delete or even sign into this. Address is : diane@shelteringhands.org Any help much appreciated. Thank you.

TalkTalk have outsourced their email to Everymail. We use Thunderbird as our e, Mail client on a pc. We have stopped getting email and can’t send any for a week now. Do I need to reset the server names suddenly.

Within the past day or so, which means 7-18-26 or later, some of my email messages on thunderbird for my pc have a "From" description that is not correct. I look at the messages, and the "From" is entirely different than the "From" description when looking at the email message list. I have never encountered this problem before. I'm using thunderbird 152.0.1 64-bit on my pc.

Hello. I regularly sign up for online conferences, then when I get the confirmation email with the details I can't transfer it to the calendar. I even tried saving the ical event separately but when I try opening it using Thunderbird I get an error message. The only way I found is to transfer the contents manually and create an event on calendar, which is time consuming. Anyone knows how to fix this? Thank you in advance

Hi,

My godaddy webmail setting which I configured on thunderbird mail for my Mac Os is not going through anymore.

It was workng absolutely fine until for over a year and now since last week I do not know what is the issue.

Incomin mails work fine, I can see the sent mail if I have sent the mail from Godaddy Webmail, but the email send from thunderbird mail doesnt work. Checked all the settings. also tried switching Port from 465 to 587

Please help !!!

thanks!

If Thunderbird startup is stopped before tabs are loaded, they are lost. The tab fields at the top of the screen remain but they are empty. Evidently, tabs are stored only in a temporary location. This is a very annoying bug. Is there a way to recover them?

Good morning,

I’m reaching out because I’m having trouble with my Thunderbird email and need some assistance.

I was using Thunderbird without any issues before, but now all my old emails have disappeared. I can still receive new messages, but I’m unable to send emails like I used to. I also can’t recover or view any of my previous emails.

It seems like something may have reset or become corrupted, and I’m not sure how to restore my old messages or fix the sending issue.

Could you please help me get Thunderbird working properly again and recover my old emails if possible?

Thank you for your support.

Someone hacked my thunderbird account and I can't get to it. How can I find the password that is now associate with it? I was told the provider has to do that, but Spectrum can't do it. I tried independent software, but the password it recovered is an old one and it doesn't work. It doesn't show up in the list of saved passwords.
