Why does the Thunderbird search for an email with certain information no longer work? It used to work OK. Now it usually fails to find any messages with the selected data. eg search for all messages that have jv16 in either the subject or body text. I know there are several in my Thunderbird but they are no longer found by the find function (although they do exist as found by a manual search).

[I was sure I submitted this but I can't find it. Sorry if it's a dupe.} Thunderbird v. 151.0 (64-bit) Windows 10

When I reply to or forward a message, I get raw code like:

Hi everyone!

I'm trying to log into my email account on the domain example.com via SMTP. The email account is with yandex.ru. When I try to authenticate, it says the SMTP password is incorrect. I decided to try through Outlook, and it worked. What could be the issue?

Tip for improving the calendar function of Thunderbird. It is said that the travel time that I enter in my iPhone, for an appointment is also saved in iCloud. Unfortunately, I cannot see or create this in the Thunderbird calendar. It would be nice if this were possible in a future version of Thunderbird.

Tips for improving the calendar function of Thunderbird I use Thunderbird 151.0.1 (64-bits) on Windows 11.

1) In a weekly overview, I do NOT see a date for each day. I would

  really like that. Then I wouldn't have to count and calculate.
 The best place would be just next to the day so e.g. "saturday 12-5"
  p.s. keep in mind that according to the country there are different form
 in Europe 12-5 means the 12th of may, i understood in America it is different.
  or 12 + the first 3 letters of the month would also be fine "zaterdag 12 mei"

2) It is said that the travel time that I enter in my iPhone,

  for an appointment is also saved in iCloud.
  Unfortunately, I cannot see or create this in the Thunderbird 
  calendar.
  It would be nice if this were possible in a future version of 
  Thunderbird.

I've had a POP3 account for years, with no problem. On a second computer I had a second TB installation that used to get its emails from a folder on the main computer. This suited our purposes very well. The second user could access all my e-mails, and her sent messages also appeared on my computer.

Alas I updated TB, and have lost this capability. Ideally I'd go back to it, but the only way forward seems to be to set up an IMAP account. I have tried this, following the instructions on the Mozilla web site. It's all very easy, but I end up with a message: "Thunderbird failed to find the settings for your email server".

I have of course checked that the settings are correct, but I can't get past this point. I have tried disabling my Internet Security (Bitdefender) but to no avail.

What should I do next, please? I'd go back to an earlier version of TB if that would enable my older method of working.

I am using Thunderbird email client for past 3 yrs and have been keeping it updated on regular basis. The present updated release is 151.0.1

Yesterday all 3 of my IMAP emails accounts stopped downloading emails. There was a red marked 97% IMAP quota used message in the right bottom about 3 days back which is not visible now.

Is this problem related to this issue? If yes, what's the solution to resolve and start using Thunderbird?

BRegs, Pankaj

I keep getting message "The certificate for imap.gmail does not come from a trusted source". I've uninstalled thunderbird on occasion and it fixed this problem, but now it keeps coming back. bold text

I am new to Thunderbird, and attempting to use it as my email client. So far I have imported my main Gmail account, a second Gmail account, as well as three different Microsoft accounts. There is a duplicate Spam folder on one of the Exchange accounts, which I assume came with the import. There is, however, no way to delete the Spam folder from the original MS account. None of the other accounts has this issue, although when I had duplicate Trash folders on Gmail accounts earlier, I was able to delete them from the original account, which allowed them to disappear from TB. The Spam messages in TB actually only populate into one of the Spam folders. Any ideas what else I can do to get rid of this superfluous Spam folder, please? Many thx for any help!

I've been trying to set up a GPG key, but Thunderbird doesn't recognize my pub.asc file. So I created a PGP key thru Thunderbird and I would like to export it as ASCII-armored public key.

As of a few days ago, I have the latest thunderbird installed and can't say when this began happening, but despite it working for years with two gmail accounts, neither gmail account will now sync / connect and it has authorization issues.

I've then tried running thunderbird in a sandbox / uninstalling / reinstalling / deleting the user profile / registry entries, you name it...when setting up a gmail account in thunderbird, an error of "Authentication error. Unable to log in at server. Probably wrong configuration, username or password." come up, despite the password being verified as correct.

If I manually setup gmail using the gmail settings, of imap.gmail.com / port 993 and SSL / TLS and Oauth2, and do a test, I'm met with "Connection to server.imap.gmail.com:993 failed"

Nothing has changed on my computer in the time leading up to this not working. No windows updates performed...no changes to the firewall etc. You name it. I've checked it all.

Strange! Any ideas? Thanks!

I have a client who has been using Thunderbird for years - in the last couple of weeks when doing his normal scan to email he is suddenly getting this error message, after filling in the email details and clicking send

"Sending of the message failed - there was an error attaching xyz.PDF. Please check that you have access to the file"

Process is... 1. do a Scan to Email via the Brother printer console panel 2. Scan completes and opens the TB new email message - File saves into the default folder \pictures\cc4\email 3. Fill in the recipient, subject and message body 4. Click send message in TB 5. Error above is presented

I can open the the attachment within Thunderbird to check it and it opens just fine - the scanned file is actually there... But click the send button and that error is presented.

I can fix it by removing the attachment and reattaching manually from the email folder where scan is saved.

When I try it myself (remote support), either via the brother CC4 app or getting client to trigger the scan to email, it often works, but invariably he calls back after his next scan to email and it is broken again...

Scans were saving to a Onedrive folder originally, moved the save location back to the standard user/pictures/cc4 folder assuming Onedrive may have been interfering, but it is still behaving the same.

Anyone have any clues what might be going on here? The brother software seems to be doing what it is supposed to. I have reinstalled both the Brother software and Thunderbird with no change... Windows updates maybe?

In the interim I have him doing scan to file and attaching manually, but would be nice to get this sorted for him...

its an Acer laptop running Windows 11 pro 25H2, TB version was 150.0.2 originally but still doing the same on the latest 151.0 that I installed two days ago

Thanks for reading... any help appreciated

When I compose a next message, anything I type exist the current window size (on the right) were disappear, until I press CTRL- to zoom out the scene. But when the same issue happened when I kept on typing. I.E. the content I was typing did not move to the next line. So that I could see what I was typing.

(example: the top line of this message, if my window is too big, I can only see upto 'the cur", then "rent window..." is out of the picture. I should move "current window.." to the next line). This is very frustrating when typing a long email. The only option I am using is the manually pressing 'Enter' for the new line.

I have Thunderbird installed for lots of users on windows 11. Recent updates caused Thunderbird to ask again to set as default, as is normal. However, if you ask it to set as default it brings up a UAC dialog. However, I have installed as a user, and am asking to change a user setting. UAC is inappropriate for the situation.

If I ask Thunderbird to uninstall is again pops up a UAC dialog even though it is not necessary and inappropriate.

Why is Thunderbird asking for more permissions?

I installed as the current user with default installer settings.

283 With Thunderbird version 140.11.1, when I click on an email, the content appears below.

With version 151.0.1, the content opens in a new window. This is less convenient. Is it possible to revert to the previous version's behavior? Thank you for your reply.
