Forum zhromadźenstwa Thunderbird

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 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.

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!

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.

Hi, I'm using Version 140.12.1e (64b). Is there any way to block and delete undesirable E-Mails om my Incoming box ? Even while being marked 'Undesirable', they stil coming again. Is there a way to erase them automatically ? Many thanks, Have a good day, Dan

I used to click the incoming Email and a box was highlighted for Reply? I have no desire to move from Windows 10. Why make it annoyingly difficult for older users?

I have changed Thunderbird E-mail account from IMAP to POP3. My question is, How do I get all my E-mail folders from the IMAP into the new POP3 account. Nothing followed the changed accounts formats.

Prelude: Monitor specs matter: Samsung Odyssey G93SC [Monitor] 1194.7 × 365 × 180.8 mm (approx. 47 × 14.4 × 7.1 inches) on a NVIDIA GeForce RTX 5080 [Display adapter] Display is 5120 x 1440 (recommended) Scale = 100% ISSUE: Fonts in Thunderbird size varies from readable to very hard to read.

Screencap below with filename [font-size-R4--181158.jpg] on your device at 100%, I hope, will show what I see.

Some Fonts in different Thunderbird 'panes' are unreadable without zooming in. The {body} of a reply is very small (see font-size-body--Rev3-07-19-2026_01.jpg below) The image will show the cursor at top left of Body.

I did search here but nothing of this nature it. So here is my question:

QUESTION: Is there a way to edit a config file or the likes to set fonts to be responsive (like a web site is same in any size screen and compensates for size?

Thanks for the read,
