Thunderbird Support Forum

Thunderbird crashed during a normal close (https://crash-stats.mozilla.org/report/index/3c0242b0-1a55-4eba-9f02-4a7bc0240126) and since then when I open Thunderbird, tabs appear for the messages I had open at the time of the crash, but they are all blank, and the tabs themselves are all empty. It is as if they are place-holders that are then never populated. I've attached a screen shot showing some of these tabs, with the crash report tab open and displayed.

About 1-2 months ago I reindexed folders due to mail apparently being missing and this resulted in a huge number of messages that had previously been dealt with becoming marked as unread again.

Ideally I would like the blank tabs to be reinstated and to be able to carry on working on my email from where I left off, but if this is not possible, I need to be able to identify the emails that were open in the tabs to be able to pick up the pieces. This is crucially important as I operate multiple accounts and it would be impossible for me to re-establish state any other way, especially in view of the earlier problem with email becoming marked as unread again. That would condemn me to needing to re-open many thousands of email items to identify those that may need action.

I renamed global-messages-db.sqlite which has been recreated and rebuilt but nothing has changed. The rebuilt file is significantly smaller than the original and if this implies that there has been data loss, I would rather reinstate the original file, if it is safe to do so.

My best guess is that the tabs are defined within history.sqlite and I have made a copy of this file but superficially it appears to contain a lot more than just tabs and it has been updated since the crash.

The most recent change I made to my Thunderbird configuration before the crash was the addition of the British-English dictionary.

The next most recent change to my Thunderbird configuration was the addition of a Proton Mail account using Proton Mail Bridge. I am accessing this account on behalf of someone who has sustained serious injuries and is unable to access it themselves. If this added account or Proton Mail Bridge is implicated in the crash in any way, I would prefer to remove the account and the Bridge software.

Many thanks in advance for your help and guidance with this problem.

as stated in the title, my HDD failed the other day and on recovery, my Thunderbird seems to have failed too.

I know (sort of) that it is all driven by the Profile.ini file.

But everytime I relaunch TB (even after what I think is an uninstall and a reinstall) I am getting : "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

I would be happy enough to have a blank TB load up and I would reconfigure my various email accounts. but I cannot seem to do even that.

I know there is a trick to getting to a Thunderbird configurator....but I have forgotten what it is.

Where does TB "look" when it starts up? how would I control that?

Hello,

I have been using Thunderbird for many years without any issues. I recently bought a laptop running Windows 11. On this machine, I have two accounts that cannot send emails via SMTP. What is puzzling is that I can retrieve emails through IMAP without any problems.

For another account I had to use STARTTLS to get it working. But on my Windows 10 machine, the same account is sending emails correctly with SSL/TLS.

Thunderbird is allowed through the Windows firewall and is on the antivirus whitelist.

I recently fixed an issue (connecting to Gmail) by allowing cookies, so it might be a simple fix like that.

Could someone help me, please?

Many thanks!

Error message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <ec2-54-219-72-248.us-west-1.compute.amazonaws.com[54.219.72.248]>: Client host rejected: NO THANKS. Please check the message recipient "patrick.gilroy@harmonydesigninc.com" and try again"

Occurs regardless of recipient, whether replying to an incoming email, or composing a new email.

We have recently moved to a new mail server. We currently have about 20 Thunderbird email clients on Windows in an office location and a macOS home machine. On all machines email is configured to use IMAP on hostname.com port 993 SSL/TLS with Normal Password and SMTP on hostname.com port 465 SSL/TLS with Normal Password.

The home machine is working 100% with no issues, it does have a much faster and lower latency internet connection than the office machines.

Many of the office machines are experiencing intermitent SMTP error messages when sending, intermitent, "unable to save mail in the Sent folder of the Inbox", messages and intermitent unable to move messages between folders.

I have checked and double checked the settings on affected machines - however, I believe a settings issue would result in nothing working, not intermitent functionality. Plus all is working fine on the home machine with the same settings (different OS, but ports and security settings all dictated by server).

With one client behaving properly, the server likwise behaving properly when addressed by the working client and the intermitent nature of the problems we are finding, I suspect we have some sort of network issue. Somthing timing out or a firewall/AV software causing a delay.

I have increased mailnews.tcptimeout on affected machines to 250 based on a forum article but this has had no effect (No idea of units here but if it is seconde then I am not supprised - the SMTP errors, when they happen are almost instantanious).

Any ideas on how to trobleshoot this problem further - The problem seems to get worse through the day, although that may just be peoples tollerance of an intermitent issue going down.

Is there a way to stop initial pop ups when opening FireFox? They slow productivity! I don't need to be reminded that I have new emails when I am already in Thunderbird.

I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.

I know this problem has been discussed extensively, but I can't fix it even after reading the previous posts.

I have an institutional email address that uses outlook.office365 server and mandatory two factor autentication. I had my Thunderbird setup with this, which suddenly stopped working one day on my office PC. I updated Thunderbird to the newest version, but the issue pertains. Currently I'm running Thunderbird 115.12.2. on a Windows 10 machine.

When I try to fetch my emails from this server, a popup window appears that asks for my institutional login credentials. When I enter them, a second window appears, asking for the two factor autentication. However, this window seems to be corrupt, as it does not contain any information, and and it's impossible to type in verification code, as there's no input area at all (see the first picture - note that I'm using a localized version of Thunderbird).

When I click on Privacy and cookies in the right bottom corner, then two lines appear (although without any labels), where I can type in my verification code (I guess that it is the second line, because it shows dots in place of the typed characters, as for passwords). A screenshot of this window can be seen in the second picture.

However, after typing the correct code and clicking on the grey button, the first window reappears, this time with my email address that keeps flashing forever and nothing happens. It does not even matter if I type in the right verification number or just anything, it produces the same behaviour. As a result, I can't log in to my mailbox, which is operational, because I can log in there through the web interface of outlook, and also from my laptop using Thunderbird 78.14.0. I also made sure that the server name and authentication methods are correct (outlook.office365.com, port 993, SSL/TLS, OAuth2).

Do you have any suggestion how to solve this issue?

Many thanks.

Updated Thunderbird to 117.12.2 on the 25 June 2024. Since then I am not receiving emails on my computer. I have actually sent some emails but they don't save into the sent folder and I have had a "Add security exception" warning occured when sending.

So problem is not getting new emails since the latest update was loaded. Thanks Neil

All morning I had been receiving and sending emails without issue. Then at approx 12:41 PM EST Thunderbird stopped working. I can send and receive emails through AOL to AOL but they do not show up in Thunderbird. I did not have any other computer issues and did not change any settings. Verizon told me it was an AOL issue, but I was able to successfully send and receive messages with AOL. AOL tried to fix it but ultimately said it was a Thunderbird issue. In the last 6 or 7 weeks I have had issues with Thunderbird. What is going on? Very Very Frustrating!!!

I can send emails but when try to receive emails I get Login to server inbound.att.net with username topgun30@sbcglobal.net failed.

I installed the new version of Thunderbird, and it's strange. I can receive emails and send emails, but I'm getting an error message at the bottom right corner of my screen:

Could not connect to the mail server (and then it names my server name) The connection was refused

What do I gotta do to make this go away?

Ever since the last update of Thunderbird, my Junk and Trash folders are empty. When I mark a message as Junk or throw something in the Trash, the messages simply disappear. I have no way of checking the Junk mailbox for messages that might be there in error. I am also unsure whether my Trash messages are being deleted permanently, or whether they are in a hidden mailbox somewhere. Please help if you can!

I recieved emails from Microsoft to update Authentication to Oauth as support for basic authentication will soon cease. Whilst I have not been experiencing any issues, after following the instructions, also provided here:

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202,

I now have an unusable Thunderbird client.

This is because I am having to keep authenticating my outlook accounts (I have about ~100 email accounts). They pop up one after the other for each account.

I believe I went through all the troubleshooting steps but to no joy.

I did notice however, when the "Enter your credentials....." pop up box appears and I go through the motions of authenticating my account and TB against my Microsoft account, the following entry appears under the Settings > Saved Passwords > Saved Logins > "Provider" column for that account:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All https://outlook.office.com/POP.AccessAsUser.All https://outlook.office.com/SMTP.Send offline_access)

The credentials include a very long auto generated password starting similar to "M.C533_BAY.0.U.-........"

A couple of things to note now regarding the oauth entry:

1. It possibly does not always get created when re-authenticating 2. After quitting TB and then re-launching TB, it dissapears

So the solution would be to somehow ensure this entry is created and it sticks even after quitting TB, since for those accounts that include this I do not have get the "Enter your credentials....." pop up box.

Is this something TB can investigate?

I posted this the other day and have had no reply or I maybe cannot find the thread. Please help.

I cannot send messages from Thunderbird since it was last updated on my pc. Version 115.12.2 (32 bit). I have checked the server settings and they have not changed in years. I have been in touch with Virgin Media, my service provider, and I can send emails when logged on to my account and not involving Thunderbird. I can also send emails from my mobile phone using Gmail. The issue would seem to be with Thunderbird and this recent update. Please point me in the right direction, bearing in mind I am not particularly computer literate.

After Thunderbird update 115.12.2(20240621154414) was installed on my PC on the 25/6/2024 I am unable to receive emails. I continue to get an error message on account noeljc@optusnet.com.au (IMAP)

   Connection to server mail.optusnet.com.au timed out.

or Failed to connect to server mail.optusnet.com.au. I have looked thru all the forums and tried various solutions without success including extending the setting for mailnews.tcptimeout to 3000. I have checked and validated my account server settings are as recommended by my ISP(Optus) are correct for authenticated emails. I even turned off my Norton VPN completely to no avail even though I use Split tunnelling to allow Thunderbird thru it as an exclusion. It appears to me there maybe a bug in the last Thunderbird update causing this. I have had this issue in the past at various times intermittently but it has always seemed to correct itself. I have been in contact with my ISP(Optus) regarding this error and all they could say was to logon to email server via webmail and did not offer any other solution. It appears there is a communication breakdown between my PC and the Email server somewhere. As I stated this only happened after the last Thunderbird update on my PC on 25/6 as it was working up until 24/6. I also have another optus email account for my wife on Thunderbird which has the same error messages. Could the Mozilla gurus please advise what to do.

First I got problem.with my laptop. I went to a service shop, but the technician caused me to loose the old files of my e mails. I seriously need help to get my old e mails accessible

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.
