Thunderbird Support Forum

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

I am getting a non-overridable TLS error when Thunderbird opens or when I attempt to download new emails (the emails will sometimes download later after I force a download. I have tried to change my TLS version without success. Please help me solve this issue.

My email setup is to an IMAP server (POP will not work with Gmail.com accounts). See my attached image files for further information.

Upon initial setup, Thunderbird says the ISP is recognized and auto-populates all the settings. Well of course these settings don't work and I'm unable to log in and receive some sort of message saying it didn't work. If I login using a browser via cellphone, I'm provided with the list of settings to use with email clients which is as follows:

Domain: @hot.rr.com SSL: On for SMTP and IMAP Protocol: IMAP Incoming Server: mail.twc.com Incoming Server Port: 993 Outgoing Server: mail.twc.com Outgoing Server Port: 587 Requires Authentication: Yes, or checked

Using these settings in manual configuration results in receiving the "Thunderbird Failed To Find the Settings For Your Email Account" message. The only difference between the settings that were auto-populated and the settings provided by logging in via web browser on a cellphone are the incoming/outgoing servers. Auto-population had them as mobile.charter.net, and they're listed as mail.twc.com by the email provider to use with email clients.

I'm trying to solve this problem for someone else and they happen to have the same email domain as me so I can fiddle with it without having to be at their computer with their passwords, etc. Presumably if I'm able to find the solution it will work for both of us. I don't normally use Thunderbird or any other email client, I just use web based email but they prefer to use a client. However, I'm doubtful that it will work considering the fact that settings provided by the email provider don't work.

Any input is appreciated.

This is probably a mess of my own making, having been lazy about back ups. My laptop threw a critical error at me just before Christmas and I could only fix it by doing a reset and reload of Windows 10. (I think it may have been a partial HDD corruption) I selected the option to retain personal data files etc, but the reload wiped almost all my installed programs, including Thunderbird. Documents, etc folders have all survived. I re-installed the latest Thunderbird and it is working fine. However, I appear to have lost my Local Folders (as well as my address book) Not a life-or-death matter, but I would prefer to recover them, if possible. I have an "..@tiscali.co.uk" (TalkTalk) email account, with IMAP settings on the incoming mail and SMTPS on "sent" items. I can see all incoming emails that are still on the server, but the "sent" items folder is empty. All local folders and contents are gone. I have read up on the Thunderbird Profile and understand that it is separate from the program folder. I have used the "Help>Troubleshooting>..." feature to find that my current profile is "zqx......default-release". Using file search, it also indicates that there is another profile file, "k32....j5.default", in the same area. Both have creation dates corresponding to the reload time. I cannot find anything similar in the "Windows.old" folder that was created at the time of the reload. Is it possible that the folder contents are still in the HDD and it is just the file address that is lost? Thanks. Neil

Hi All, Greetings!!! For the past two days, I have got the error like "Sending of the message failed. The message could not not be sent because the connection to Outgoing Server (SMTP) timed out". So I have restared our router (Broadband Modem), and then tried to send the mail, but the result is same. Then I have tried using my mobile network (using hotspot method), this time mail was sent sucessfully. Please help me to solve the issues...

Thanks Karthik

Here in Jan 2024 suddenly TB will no longer connect to any hotmail or outlook..it says I have to enter a new password but I have not changed my password and can get onto them if I go directly to that site. Any suggestions?

I use dark mode (Windows 10 Pro, Thunderbird 115.4.2 (64-bit)). Fresh installation, fresh profile. When I reply to some emails, the reply text is not visible. The examples I saw were with a light (white?) background, but I'm not sure if it also happens with other backgrounds. But it's not all white backgrounds either, some emails with a light background I can reply to just fine.

The reply area can be dark with a dark grey font (slightly different color), or it can be white with a white font. In both cases, obviously the text I type is not readable.

Any idea how to fix this?

I get this message from Thunderbird on my desktop computer on app start up: ]Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

This started suddenly about a week ago.

I have Thunderbird on laptop that works fine.

How can fix this?

I need help to organize the folder structure that was messed up during update to Thunderbird 115. Most urgent is one inbox folder which is now found under the accounts folder and not in the general inbox folder with all the other inbox folders. I would like to beable to move this misplaced inbox folder to it's original place in the general inbox folder.

Also in this misplaced inbox folder, its has other folders in it: template, draft, sent etc. These folder should stay in the accounts folder.

I hope that a future update will clear the mess, and other solutions are welcome :-)

Hello, I have Thunderbird running on two different OS's. Linux (115.3.1) and Windows 11.(115.4.1). Both act the same way. Both are have the same email address and are linked to two gmail accounts. I have noticed that web based gmail email there is only a "Sent" Folder. On Thunderbird there is a "Sent" and "Sent Mail" folder. on one account the other only has "Sent" They are not always in sync. When I send an email, sometimes it seems to "Hang" sometimes not. I am wondering if I can remove the "Sent Mail" folder or the "Sent" folder as that could be causing the problem?

Thanks in advance.

I downloaded the new version of Thunderbird Mail, and now, I'm having continual trouble sending messages (but no trouble receiving them). A pop-up window keeps appearing requiring me to re-sign into my Microsoft account, for some reason, but whenever I press "continue" to sign in, nothing happens, and selecting "cancel" also has no effect. I'm already signed in to my Microsoft account on my laptop, anyway, so I don't know why this window keeps appearing, but I assume it's related to the fact that I'm having trouble sending e-mail. I have to keep closing the Thunderbird program and re-opening it every time I want to send new messages. This is becoming very tiresome. I've already tried closing and re-opening the Thunderbird program, but that doesn't fix the problem. I'm working on a Mac, with the latest iOS. All suggestions appreciated!

I'd really appreciate any help you can give me.

I've been using Thunderbird for many years.

TB has been working fine for all those years. and I have probably thousands of emails stored. Then, I went on a trip Sep 28 to Oct 14 and did not use Thunderbird for about 17 days. On my return, I tried to open TB. I found that a screen opened that I hadn't seen before, and TB seemed to be loading. While loading, at the bottom of the screen it said "Checking inbox for new messages...". Then, after a while it crashed without ever opening.

I tried to open TB several times after that, and I've always gotten the same behavior -- ending with a crash and never being able to open TB.

During the loading once, I clicked on Help >AboutThunderbird, which showed 115.3.3.(32-bit) and "Downloading Update 2.4 of 5.4 MB."

The last four Crash Reports, all dated 10/31/2023 are (the last one being the latest): bp-e634fd35-1b8a-488a-a9df-c23050231101 bp-73858652-569e-4362-95d6-030490231101 bp-992529bf-d1af-41d9-a438-43c370231101 bp-c39563fd-bca7-406f-8abf-85bde0231101

I thank you very much for your assistance. D. Prerau --prerau@rcn.com

I am using version 115.3.3 just today I started having problems. My default Windows virus checker did not identify any issues and I ran malware bytes and it showed zero problems. the problem seemed to start at the point when I forwarded a 5mb file to a few friends. Since then, I have been unable to send anything. The system continues to crash. Most of the time I cannot see any information in pull down lists. I have tried rolling back to a week old restore point and it continues to have the probem. I have tried updating to 115.4.1 and it still has the problem. I have removed all of the automatic installed updates from the last two days and still have the problem..... HELP!

I am not sure I will see emails back from this help request, but I sure hope so:)

My colleague has updated his thunderbird to version 115.4.1. He As operating system he has windows 11 Home Version 22H2. His "old" thunderbird worked perfectly.

Now he has the following problem: If he writes an e-mail, the "send" button is missing. I've found nothing but a solution in my research. However, he can easily receive e-mails.

Do what?

Hello, Can anyone help with server issues? I'm able to sign in and open Thunderbird but i can not receive or send any emails. It states my server is the issue but i attempted everything i saw online in regards to turning on and off my proxy and firewalls as well as checking the port was 587 for outgoing but its still not working can someone assist me in fixing this.

I select multiple files in File Explorer and select, right click, Send To, Thunderbird, but only one of the files actually appears in the Thunderbird email. It appears that which one shows up as an attachment to the email is quite random. This used to work fine with all the selected files showing in the email, I haven't upgraded anything so far as I know, and I don't think I have changed anything at all. Any ideas most welcome. Incidentally, if I select only one file to send then it works fine; if I select multiple files to send through Outlook, then that works fine. I just cannot send multiple files through Thunderbird. I am using Thunderbird version 115.4.1 (64 bit). I have looked at the issue on Microsoft pages and they are of the opinion that this is a Thunderbird issue, not a Windows one. Thank you for your help in advance. Cheers

After upgrading to Thunderbird 115 I've tried reading a long email scrolling down to view the lower half. After about 30 seconds it Thunderbird automatically scrolls up to the top of the email again and again without even touching the mouse. Thus making it difficult to read the entire email.

This version of Thunderbird is installed on a Macbook Computer booting up to Windows 10 operating system.

I've tried turning off auto scrolling and hardware acceleration with no change in behavior.

Should I roll back to an older version of Thunderbird or does anyone have a solution to try?

Thanks you for any suggestions.
