02 Oct. 2025

Recently, some automatic updates were made to my Dell desktop. I assume they were updates to the Windows 11 OS.

The updates also caused some changes to my Thunderbird e-mails. The incoming e-mails are formatted differently. I used to get a message, saying that "remote content" in some incoming e-mails had been blocked. I was given the option to show remote content in the incoming e-mail. Now, I no longer have the option to "show remote content".

Please tell me how I can recover the option to "show remote content" on incoming e-mails.

Thank you.

'For some months Thunderbird is not displaying all the messages received. Inbox says there are nearly 1600 messages in there somewhere, but only displaying about a dozen. Fresh reopening might suggest, say 8 emails have been downloaded, but perhaps only 3 of them show on Thunderbird. If I go on the net to my ISP (Hotkey /iPrimus) the missing ones show up there. I have tried removing and reinstalling Thunderbird without fixing the problem. I tried the repair files button but no difference. Any suggestions? Hotkey say it's not them. I can send a screenshot if needed

I'm moving to a new computer and am having trouble getting the migrated Tags into the correct numerical order, same as on the old computer. Because the numerical order corresponds to keyboard shortcuts, it would be so very helpful. I know there was an extension that allowed you to set the order, but it's listed as through version 38 or therabouts, so I'm not sure if it would work. I figure maybe I could edit a Tag preferences file if it's in some sort of obvious text format. If anyone out there knows, I would be so grateful for your insight. Thanks.

Over a month ago I began experiencing an error message when attempting to send emails from my gmail account using Thunderbird (TB). Error msg reads: Sending of the message failed. An error occurred while sending mail. The mail server responded: Must issue a STARTLS command first. For more information go to: https://support.google.com/a/answer/3221692 and review RFC 3207 specifications. 00721157ae682-765bb916a90sm38332507b3.4-gsmtp. Please verify that your email address is correct in your account settings and try again.***While I have looked at all of this, I can't really find a solution I know how to implement.***

I can send emails using Google webmail and when I do, the emails show up in my TB Sent items folder. I'm totally stumped and considering moving to Outlook. But TB has been perfect for me for years and I want to stay with it. Any help will be much appreciated!

I want to add school e-mail account to Thunderbird cause I already use Thunderbird for my private e-mail. If I try to connect the school e-mail account to Thunderbird, it loads and loads and loads but never gets the IMAP and SMTP settings from the server. It tried to add the account in a new install of Thunderbird in a virtual machine and there was the password input at the start to the usual name and e-mail input, when adding a new account. There it worked and Thunderbird got the settings from the server. But I don't want to access my school e-mail account via a virtual machine. I want access through my own PC. So it looks like the server needs the password from Thunderbird to get the settings but there is no way to input it before requesting the server. Or is it? Thanks for help in advance.

皆様、はじめまして。 先日、ThunderbirdにGmailアドレスも追加登録しました。 が、パスワード変更が必要になった為、Google で Gmail のパスワードを変更した後に、Thunderbirdに登録しているGmailアドレスでは受送信出来なくなりました。 従ってThunderbird での Gmail送信エラー画面でパスワードを変更しようとしたのですが「新しいパスワードを入力」への入力を受け付けてくれませんでした。 更にパスワードリストで変更出来るかとリストを出そうとしましたら、Thunderbirdがユーザー名とパスワードを聞いてきました。 でも、ThunderbirdはPCが変わっても、ダウンロード、インストールさせて頂くだけで、メールアドレス等の設定をすれば使えますので、敢えてユーザー名やパスワードを登録した記憶がございません?

結局、「その他」を選んだらPINを入れることによってパスワードは見られたのですが。 後でパスワードマネージャーのリストを見てもThunderbird は載っていませんでした。じゃあ、パスワードマネージャーは何というユーザー名を入れたのか?判らず気になります💦

Thunderbird が「メールアドレスのユーザー名」でなく?、単に「ユーザー名」と聞いてきた場合、何を入力すれば良いのでしょう? 登録した複数のメールアドレスの中のどれかを入力すれば良かったのでしょうか?

その後、Googleから本人確認をしてきましたので、Gmailのパスワードを入れ、スマホで「はい、私です」をクリックしたら、ThunderbirdでもGmailの受送信が出来るようにはなりました。

ただ、もし、Thunderbird ソフトに対するユーザー名とパスワードがあるのなら、なんとかしないといけませんので、お尋ねしております。(初めてThunderbird を使わせていただいた頃のメールアドレスはスパムの為に削除して無くなっております。)

よろしくお願いいたします。m(__)m

I am having trouble moving Thunderbird data from one computer to another. The first computer is Windows 10 32-bit that has been running T-Bird 140.3.0esr for several years. The second is Windows 11 64-bit running T-Bird's latest version. I tried both procedures cited in the Mozilla article at https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer.

I first did the 2nd method cited -- Win 10 to Win 11. It worked but the new computer is missing Local Folders and contacts organized as groups.

I then did the 1st procedure cited, using copy and paste commands. It did not work at all and now T-Bird will not load. I get this message: "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

So, different operating systems with different bit specs and different T-Bird versions.

I thought of updating the Win 10 computer to T-Bird's current version and then doing the Win-10-to-Win-11 copy/move procedure but thought it best to ask here first. Thanks for any help.

Hello people,

When I compose a message in my word programme (Softmaker or Libre), save it in Docx format and copy/paste it into Thunderbird to send it everything is double spaced and nothing I do in the "compose" menu can change that.

I have tried it with "Use Paragraph Format" checked and unchecked and it stays doule spaced and nothing I can find in previous threads seems to address this problem.

What am I missing?

Kindest regards, Colin B 1 October 2025

I was sending emails just fine last night, I can send them fine from the web browser, and I can do it fine from mail app on my phone. But when I try to send it from Thunderbird, I get an ongoing error with the following:

Login to server smtp.office365.com with user name my email address failed.

I have already checked the settings, and I changed and re-entered the new password in Thunderbird, and while I can still receive emails I cannot send them.

Here's an exact image of the settings I put, minus my blacked out email address.

I've tried two different email addresses to send to, including a test email to my own address, so I'm at a loss what to do. Have also closed, and restarted Thunderbird, and my whole PC.

I am receiving emails just fine, and I changed nothing before this error started, I double checked everything, even my email address, and copied my outgoing email address name to my online mailbox and sent myself a test email just to be 100% certain it's correct.

Hi, Updating Ubuntu 24.03 to 23.10 something went wrong and the disk is no longer bootable. All the files appear to be there, but since its not bootable I can't export the data in the normal fashion.

I installed Ubuntu 24.04.3 LTS on a new disk, and mounted the unbootable disk on /oldDisk. My home directory and everything else appears to be intact.

What do I need to move from /oldDisk to the new install to get my address book and emails back?

until I get this fixed you can email me: <redacted>@evvette.net as my account address won't work... thanx in advance, Steve

Since eclipse 140+ rolled out there is no longer a high contrast colour override, I dug through all the settings in case it was moved but I am either not seeing it or it's not there anymore. Does anyone have an option or work around for enabling high contrast without me having to roll back my version or install a different email client?

I've been using Thunderbird for year on my desktop. Just got a new one and I can't get Thunderbird to start. I have NO IDEA what the "set-up" wants from me. The most recent error is "Authentication FAiled. Please check the username and password."

I JUST reset the password. What does Tbird think my user name is if it's not my name???? And why doesn't it give me an option to find out what it has stored somewhere for me??

My friend was unable to configure his outlook.com email address in Thunderbird (143.0.1) while I had no problem doing so in mine (140.3.0esr). We both had installed other email addresses already configured with no problem. I upgraded my second laptop from the esr version to his recommended release version, and hey presto, I suffered the same fate. This is definitely a bug within Thunderbird 143.0.1 which is the current release version.

I had not previously added the outlook email to Tbird as it is not my main email address.

More info: The error message encountered was:

Authentication failed: Please check the username and password

When you click on the "More information" link, it says:

"Exchange auth error"

Please note that we checked the username and password and verified them as correct. I addition, I was successful using that username/password on the 140 esr version and it worked perfectly.
