Thunderbird Community Forum

I have been receiving emails and newsletters from a number of companies for many years. Suddenly last December many stopped coming. I have been in touch with one in particular and I am still on their mailing list. I am unable to find anywhere I can check. And before anyone says check your Junk folder. I do that every day. It has gotten to the point where I will have to stop using Thunderbird. Where can I look to find out what is wrong.

I had to reinstall Thunderbird after a crash. Before, my inbox was split in two. The top half was the messages and the bottom half a preview of the selected message. Now I just have one long list of emails. Please can you advise how to go back to the split screen view. Many thanks.

I have thunderbird 128.1.1 load on my computer. Every time it loads it asks for the pop.gmail password. I just had to change all my gmail passwords for fraud protection.

Thunderbird will not accept the new passwords, keeps returning to the the same screen. Recognized that password from google had been changed, but won't accept any passwords from google

Not running firewall, VPN or antivirus program.

Even when I had to change signature information in accounts, it does not keep the data like I was never there. I had 1 gmail account I added and next time I opened thunderbird it was not there.

Hi, I've been using Thunderbird since it's inception in 2003 and so far have been delighted with all the innovations and changes which have occurred since that time. However, I have only recently come across a very unusual ocurrence:

MY PC specs: Device name DESKTOP-EK6DE3O Processor AMD A8-9600 RADEON R7, 10 COMPUTE CORES 4C+6G 3.10 GHz Installed RAM 16.0 GB (15.0 GB usable) Device ID 1BEB8A9E-543E-458C-A36D-83606B41F757 Product ID 00326-00828-84284-AAOEM System type 64-bit operating system, x64-based processor

Mozilla Thunderbird version: Version 128.1.1esr Build ID 20240820161839 Distribution ID Update Folder C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\D78BF5DD33499EC2 .

So, my problem is that I have a 50 odd list of email addresses which I send BCC. This list is called "Playlist" (nicknamed "BCC mail out") and in the past I have been able to click on that name, in the BCC field and then send after writing in body of email. Very recently, last week in fact, when I click on that BCC list "Playlist" and then try to send, the following message appears: "BCC Mail out < > is not a valid email address because it is not of the form user@host. You must correct it before sending the email". I adopted this method years ago and found it really fast and very convenient, yet now I have to go into address book; highlight all the addresses in "playlist"; change from To to BCC, then add To (and aslo CC)(for different addresses). Sending this way still works, but seems a very round-about way of doing it! What has happened in this version of Thunderbird compared to previous versions? Can it be resolved, please? Any chance of making it 'backwards' compatible? You all do a great job. Regards Dave

Hello,

Since some days ago, my Kaspersky antivirus has detected trojans from emails of January 2021. It seems like Thunderbird saves a backup from old emails on our system, and these emails contain spam and trojans.

See attached image. All of our computers show same issue. And it happens with more than 50 old emails. Also I have attached the path of these emails, where the issue has been detected by Kaspersky.

How can I remove these old emails and configure Thunderbird not to save old emails backups?

Best regards, Alba

Hi - I can't send emails from Thunderbird. I get a message (see attachment). The last time it worked normally was Friday. Since then the window with the message in it appears each time. Anybody know what the problem might be?

Mircosoft has indicated that after Sept. 16 it is not possible to access my e mail account on outlook. They require a more modern/sophisticated method of authorization, login and password is not enough. What to do?

Text (in Swedish) from the e-mail that I received from outlook@communication.outlook.com:

Det här måste du göra

Om du får det här e-postmeddelandet använder du för närvarande en e-post- eller kalenderapp som ansluter till ditt Outlook.com-e-postkonto genom en mindre säker autentiseringsmetod. Du måste uppgradera din e-post- och kalenderapp från tredje part till en version som stöder moderna autentiseringsmetoder.

I had all files downloaded from my old PC to an external harddrive and uploaded to a new PC. My Thunderbird account does not appear on the new one. How do I correct this?

Thanks for any help with this.

I tried to do an import of a backup profile that was very large, greater than 3 GB. System says this file is too big to recover. Error console is as follows:

I cannot see any mail in my inbox even tho it says there are over 300. When a message comes in, it disappears after a few minutes.

I have searched the forum and have not seen my issue.

Any help would be appreciated.

Thank you

In Thunderbird, which I have used for years, there were some 95 messages in a folder. For some unknown reason (did my mouse finger slip perhaps?) they disappeared. I can see them by using "Search", but would very much like to restore them to their folder -or any folder. Can someone advise?

I have (I hope) attached a screenshot of what ""search" produces - any idea as to how I can get these messages back into a folder? I've tried making a new one, but that didn't work.

I'm trying to copy the data from a PC running xubuntu 2022 onto one running Ubuntu 2024.

I'm following the instructions here (https://www.google.com/search?channel=fs&client=ubuntu-sn&q=moving+thunderbird+data+to+a+new+computer) and all seems to work up to and including "On your destination computer" step 7 (Close Thunderbird). Step 7 "From your Thunderbird profile folder in File Browser, go up two levels" - this sends me to "Common". Step 8 Right click inside the folder, then select Paste.

Here's the problem: we're not told what to click on, but I assume it's ".thunderbird", which only contains 11 items although apparently 348 were transferred. Clicking on empty space (I tried that in desperation) doesn't work. I'm probably overlooking something obvious, but I can't see what that might be. Any suggestions gratefully received. In the meantime, I will keep trying and if I somehow get it to work I'll let you folk know.

We travel to FL for winter months and occasionally North for summer. In the past we have had no problem moving our profile between the two systems. This spring when we returned from FL, when the Profile was put on the DT at home, we saw major differences. We had always dealt with POP systems so we stored all email on a local system. We, my wife and I, have 5 different email addresses, all of which WERE on the same inbox. After this spring move to DT, all 5 had different accounts and inboxes. After this, our old inbox was stored in Local Folders. This we could live with. BUT

The remainder of our local folders were incomplete. We had about 1/3 of what was on the Laptop available on the Desktop. There was an unused Profile that had all of the Local Folder folders in it. It had taken me about of month to explore the difference, we had other things to do including an emergency trip back to FL to determine whether our condo was flooded with sewage as our next door neighbors was. It wasn't!!

So, I have tried a simple copy and paste to move the many missing Local Folders, both mozmsgs and sbd, to no avail. Is it possible to update my current Profile with the older info. It appears both DT and LT are the same version of Thunderbird. If so - please help this old computer hobbyist. I started in 78 with an IMSAI and CP/M writing printer drivers in assembly. Since then, a lot has happened and I'm no longer "up to date".

My send button has disappeared. I think it was after I removed a menu including "encrypt" by accident. I have tried following some of the suggestions on earlier posts, but when I go to "customize" there is still no send button. How can I restore it?

Hello, we have added a new email address and currently it is not possible to send emails from any email address in thunderbird. It reports an error: Failed to send message. Authentication on the mail server (SMTP) was not possible

I recently upgraded my computer and re-installed Thunderbird with my several e-mail accounts. Somewhere, while setting up my various accounts, I used a comma (,) instead of a dot (.) in the account name; i.e. cxxx,xx@comcast.net instead of cxxx.xx@comcast.net. Now, when I try to send a message from that account I get the error message shown below. Receiving messages is not affected. My equipment is a Dell Optiplex 7010, 13th generation i7 CPU (x64), 16 Gb RAM, Windows 11 Pro, Thunderbird 128.1.1esr (64-bit). I cannot find a location or means to correct the comma vs. dot error anywhere in my Comcast account or in Thunderbird. What do you suggest? Thanks... Jim <jmcarp43@gmail.com>

Error message (can't send full screen shot):

Login to server smtp.comcast.net with username carp,jm@comcast.net failed.

Hi

I use Thunderbird on Windows (now 11) for 16 years now. Currently I have Thunderbird version 128.1.1. I would like to share profile between Windows and Linux (Ubuntu 24.04) installations on same machine. Profile folder is in a ntfs partition accessible both from Ubuntu (automatically mounted) and Windows. I managed to edit profile.ini file to point to right profile folder. On Windows evenrything workes fine. When I try to open Thunderbird in Ubuntu I get empty folder list and no account information in configuration. In the profile folder there ale many files created with names ending with corrupted are created (like folderTree.json.XXX.corrupt). Another try to open Thunderbird ends with message that profile is already in use. Any advice? Maybe I should debug starting Thunderbird (if yes let me know how to do that).

Thanks in advance. Marcin
