Hello, I'm using Thunderbird 115.1.1 (thunderbird-flatpack - 1.0) on Fedora 38 Workstation. Thunderbird crashes immediately when I want to print an e-mail. The dialog box that then appears indicates that no trace has been created.

The problem persists if I run Thunderbird in safe mode.

Any ideas on how to solve this problem? Thanks, Chris.

Greetings. My Thunderbird for Windows auto-updated to 102.3. I'm sorry, but I have no idea what the previous version was but it was working fine. Now when I run it newly auto-updated, I am not able to see my four e-mail accounts on the left (all IMAPs) and therefore any message. My accounts are still there and the software is still fetching e-mails and showing new e-mail notifications as normal. I just can't see anything in the main menu. Attached is what it looks like on my end. I have tried restarting my computer and also downloading/installing/running the 64-bit software rather than the 32-bit. Any ideas would be appreciated as it is cutting into my personal productivity right now. Thank you for your time.

I have two email accounts that go to my one inbox. Always was fine. But now with 115.6.0, I cannot change the From account by just opening the little drop-down after opening a reply. They are both there, but I can't change.

Hi,

TB 91.5.0 on Windows 10 (with profile folder excluded from virus scan)

The latest update to seems to have resurrected a problem with saving copies of sent emails. Sending works fine, but copying of the sent email to the sent folder causes the send dialog to hang. Disabling the "Place a copy in:" option in account settings eliminates the problem. Using the "Other" option to place it in a local folder works *that is not part of a unified folder* works OK.

I have tried repairing folders and deleting the sent files inside "smart folders" in the profile, with no luck.

I've used Mozilla Thunderbird almost since its inception. The current version is 102.11.0 (32 bit), running on my PC, Windows 10 Pro, version 10.0.19045.

I have two e-mail accounts that I use, from the same server/provider. One account I've been using for about 20 years and the second account is more recent. The older account is used almost exclusively, and the newer account is used much less. On the older account I annually archive the inbox messages to folders by year, to keep the inbox fairly clean. Most recently my inbox contained messages from 2022 and 2023 to date.

I've experienced an annoying problem on the older account for the past several months. Each message that comes in arrives in duplicate, requiring me to go through the messages daily and delete every other one. I noticed that there were a very few senders whose messages did not come in duplicate, for some reason. I updated to the present version about 10 days ago, hoping it would solve the problem but it did not.

Then, about a week ago I could not open the inbox. The message said to wait while Thunderbird processes the inbox and when it finished the inbox was empty except for a few random messages from years ago.

I also have not been receiving any new messages in that time. I do receive the e-mails on my iPhone and my laptop with no problem, and I do not experience the problem with my newer e-mail account. Can anyone help me get my inbox back and start receiving e-mails properly again? Help, please!

Hello, After updating the Thunderbird email program from version 102.15.1 to version 115.4.2, each new email received with a (checked) .pdf, .docx downloaded to disk 0 Bytes and displaying an empty document. Create it directly in Thunderbird, it's also impossible. In the case of this message to another sender who has Thunderbird 102.15.1, it opens without any problems, forward it to the recipient who has access to the 115.4.2 version, it already opens ten files and saves it to disk in a size that has ten files. Strange thing, it works, but it can't be like that. Please let me know what could be the solution to the problem.

Regards

I've been running Thunderbird for years on Gentoo which has version 115.10.1 as the most recent. I don't send much mail so I'm not exactly sure when this problem occurred, but I'm unable to authenticate with my SMTP server. I have not changed any configuration. Some weeks ago a changed my password on the server, but I made the appropriate changes to Thunderbird password manager. All settings, username and passwords are 100% correct as I copy pasted all of them. IMAP on the same server (uses same credentials) works.

I have tried deleting and re-adding my accounts which did not help. I have also tried deleting my profile folder. All other mail clients (e.g. claws-mail, kmail, mailspring) with the same SMTP server don't have any problems sending mail. This problem seems to only affect Thunderbird and Thunderbird forks such as Betterbird.

I have no firewall and am using SSL authentication with cleartext password on the SMTP server.

I get the following output to console on attempted sending of message:

console.error: (new Error("Server error 503 Service Unavailable", "resource://services-settings/Utils.sys.mjs", 390)) console.error: mailnews.smtp: "Command failed: 535 Incorrect authentication data; currentAction=_actionAUTHComplete" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.send: "Sending failed; Unable to authenticate to Outgoing server (SMTP) mail.kapsi.fi. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'., exitCode=2153066805, originalMsgURI="

For many years, my wife and I have each used Thunderbird on our own computers. Several weeks ago, when my wife turned Thunderbird on, a new screen appeared that mentioned account setup and directed her to set up her existing email address. When she did, a home screen appeared that was significantly different than the one she had been using. But more than that, she lost all her saved emails and Thunderbird started to reload emails. The reloading ended with over 1800 “new” emails whose dates reached back for almost a year. Since then, after some work, the home page has been returned to its earlier look; downloading, sending and deleting are working as before. Missing are a few important, personal subfolders. We’ve tried a few things that we thought/hoped would return us to the point before everything went crazy. That hasn’t happened. Recently, we looked at the Profiles folder on each of our computers and saw something that, I think, is unusual and, I hope, might provide a way get her back at least some of what was lost.

The route to my Profiles is C: > Users > Me > AppData > Roaming > Thunderbird > Profiles In Profiles are two folders, one ends with .default and the other with .default-release. The only thing in the default folder is the file times.json. The default-release folder contains many files and folders, including the Mail folder. The Mail folder contains two subfolders: Local Folders and mail.comcast.net.

On my wife’s computer, there is only one folder inside Profiles. The name ends in .default. Inside that folder is the Mail folder. Within the Mail folder are six subfolders: Local Folders, Local Folders-1, Local Folders-2, mail.comcast.net, mail.comcast.net-1, mail.comcast.net-2. The Date Modified date for Local Folders is probably the date the problem started. Date Modified for Local Folders-1, mail.comcast.net and mail.comcast.net-1 is the same: a few days after the date for Local Folders. The dates for Date Modified for Local Folders-2 and mail.comcast.net-2 are the same, and change daily.

I’m hoping/assuming that the missing, personal subfolders are in one, or more, of Local Folders, Local Folders-1, mail.comcast.net, mail.comcast.net-1. What I’m asking here is: does anyone know of a way to easily locate and recover the subfolders and, then, move them into the correct location in Local Folders-2and/or mail.comcast.net-2.

Thanks for taking the time to read this long story.

Thunderbird pauses while drafting an email. It does this while connected to the internet. When disconnected from the internet, this does not happen. Is TBird checking something on-line? How can this be disabled, it is quite frustrating as the pause can be several seconds long. It actually types ahead but does not display the typing until several seconds later. Any help is greatly appreciated.

When I attempt to to into either the settings page or the contacts page, they will only appear in about 1/3 of the full screen making it impossible to see the remainder of the information on that screen. It is impossible to edit a contacts information on the screen. I have the screen set to maximized, and no Add-ons installed.

I have attached a couple of screen shots to show what it is doing

Currently using Thunderbird 102.7.2, but this issue has been ongoing for sometime

Thank you

Hi all

Since yesterday Thunderbird is unable to connect to the server and download new emails.

I got the following error message: "Non-overridable TLS error occurred. Handshake error or probably the TLS version or certificate used by the server mail.blacknight.com is incompatible."

I am running Thunderbird v102.2.2 for 4 days now but yesterday was the first time this error has appeared.

security.tls.version.min is set to 1. In fact, it has been set to 1 for more than a year now.

The host tells me everything is fine with the cert used by their server.

Any ideas or help would be greatly appreciated.

For years I have been using Thunderbird on Windows (10 and 11) to access a newsgroup via the news.individual.net server. After I upgraded Thunderbird from version 91 to 102, I had the problem that trying to get new messages would just cause Thunderbird to stall., with the oscillating dot in the title bar. If I ask it to refresh the list of newsgroups, it tells me "Error retrieving items from the server".

I deleted the account and recreated it. It found my newsgroup fine and downloaded messages - once. If I tried to get more, it was back to the stall.

I have tried switching between SSL and non-SSL access, to no effect. "Troubleshoot Mode" shows the same behavior. "Clear Startup Cache" also has no effect. This server does require a login.

For the last 6 months, my ip gets blocked from my website server about once a month. This causes me to locked out of my website until inmotion unblocks my ip. It works fine for about a month and then ip blocked again The conversation below was with my hosting company Inmotion hosting

4:35:48 PM) Andrea J.: Looking at the error, I can only see failed logins for alan@wood-r-us.com. (4:36:02 PM) Andrea J.: I have unblocked the IP for you. (4:36:16 PM) Andrea J.: So you should be able to access the server now. (4:36:54 PM) Alan Johnston: Yes my email is working again thanks. (4:36:59 PM) Andrea J.: My pleasure. Was there anything else I could assist with today? (4:37:20 PM) Alan Johnston: What can be done so this does not keep happening about every month (4:38:32 PM) Andrea J.: You will need to locate the device that is having the login issue, (4:39:14 PM) Alan Johnston: That is the only email related to this site and It is me. I use thunderbird and I stay logged in all the time (4:40:11 PM) Andrea J.: Mar 13 15:49:30 ecbiz320 dovecot: imap-login: Disconnected: Connection closed: read(size=720) failed: Connection reset by peer (no auth attempts in 3 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85, TLS: read(size=720) failed: Connection reset by peer, TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Mar 13 15:49:31 ecbiz320 dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 0 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85, TLS handshaking: Connection closed Mar 13 15:49:31 ecbiz320 dovecot: imap-login: Disconnected: Too many invalid commands (no auth attempts in 0 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85 Mar 13 15:49:31 ecbiz320 dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 0 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85 Mar 13 15:49:31 ecbiz320 dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 0 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85, TLS: Connection closed, TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Mar 13 15:49:32 ecbiz320 dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 1 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85, TLS handshaking: Connection closed (4:40:37 PM) Andrea J.: Looking at the server, the logs shows connection errors.

I have 2 mail accounts synced to TB. Both are hotmail accounts. I can send emails from 1 but not the other after updating TB from 102.15 to 115.2. Everything else seems to work. I've changed no settings and they seem correct as far as I can tell. When I try to send mail from the problem account, a blank browser pop-up comes for a few seconds (authentication?) then disappears; then, the "sending" bubble comes up and then times out giving this error message: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again." What is a solution for this? Thanks in advance.

I have Thunderbird 115.0b2 installed and using unified folders. When I delete a message from my inbox or even any of my local folders, the deleted message does not move to my Trash folder. Basically, the email is gone. I looked through all the various TB settings and cannot find any that would cause this action. I really want the deleted emails to go into the Trash folder in case I make an error deleting the wrong email one day. Any suggestions are welcome.

Thank you, Steve

Hello, someone solve this problem ? I can't setup new account in Thunderbird 102.4.1 . I have 3 active IMAP account on my Thunderbird and when i want to set a new IMAP account the Thunderbird will stay in "Checking password". IF i press the cancel and i want to add again the messages is "Incoming server already exist" I found this problem to more users which are using this version of Thunderbird. On the other PC i uninstalled this version and i reinstall another older version and everything is ok. On my pc i don't want to uninstall thunderbird because i have a lot of email structured and configuration. I attached a screenshot with this error.

Hi,

I've recently tried connecting my Yahoo account to my Thunderbird client (102.12.0 (64-bit) on Windows 10 but it refuses to connect. I add the account and use the recommended settings, I get through entering my email, password, checking I am not a bot, and autheniticating using an app but then it just reverts back to asking me to entering my email again (screen shot 1) and never connects.

I have a VPN but the issue remains when it is turned off. I have also tried logging in to my email in Firefox and this works fine so there's no issue with the credentials at all. The settings are the standard (second screen shot)

Can you advise please as this is my main email address and I'd like it working, as has done for years, in Thunderbird.

Many thanks

[EDIT] Antivirus was the cause. Had to add exceptions for https://mail.yahoo.com and https://login.yahoo.com in my antivirus settings to finally get access

I was able to send emails till July 14. After that day it's been impossible to send or reply to messages from my Outlook account (I receive emails though). I have made no changes to Thunderbird's configuration since then. Basically it's the Oauth2 authentication that fails. I briefly see a browser page for authentication, wait, wait, wait and then the mail is not sent and I get an error message related to servers timeout (attached). Sorry, my interface is in Italian, but anyway the message is something like: "Unable to send email because of a timeout on the connection to the out server (SMTP) smtp.office365.com. Try again." Is this a known bug? Any ideas? It's quite annoying to use the browser interface to send messages while I am able to receive them in Thunderbird :) Thank you in advance, guys!
