Within my means, i am a keen su[[porter of Thunderbird, but I must confess I am really getting fed up with it. Recently I have been having A spate of problems. I recently had a problem where all my inbox mail ended up in my trash folder and you provided help to solve this issue, thank you. No sooner had that been fixed when I then booted Thunderbird up and, although all folder in the left hand page were there, all present and correct, there were were no emails listed on the right hand side except the Thunderbird home page. Do I just give up on Thunderbird for fear of what next problem looms up unexpectedly?

Hi. For a long time, I've noticed that emails I send from home are sent, but those I try to send with the same settings do not get sent when connected to the Internet in 4 out of 4 cafes. My ISP, Zen, hasn't been able to explain why. I've tested whether Google VPN blocks it somehow, and it doesn't. I normally use Thunderbird. Today, I found that, in the same cafe, messages I tried to send using Thunderbird failed to send, whereas there was no problem with GMail, Proton Mail or Outlook. Any suggestions?

W11 rig. TB updated today to 138.0.1 (64bit). All message on inbox show up ok, but all messages on the local folders are blank.

But I can access all email in all folder from my W10 rig which is running 128.9.1 esr so I know the msr files etc are not corrupted. This is only happening on the w11 rig

Repair approach makes no difference when tried through the w11 rig. Have rebooted w11 computer, reloaded TB several times. No change.

Need suggestions to get the W11 rig working with all messages. Thanks

I can no longer access Thunderbird emails or send emails. I tried doing a New Account, but get a "can't find" error message. I closed down my computer and took out the battery, I deleted and reloaded Thunderbird, I did my manual settings, I did the New Account settings repeatedly, and I tried the Thunderbird look up. Nothing gets my email back. Everything else works on my computer as it should. Gmail works and my link to my IP gets me email through their site. I can't send or receive at all, and my previous emails are now gone.

I've been using Thunderbird for years. It connects to my gmail account using POP. I'm on a Windows computer using Windows 11 and Thunderbird says it's up to date with version 128.10.1esr.

For the past couple of weeks my Sent folder has been empty. Emails are sent successfully, they're just not stored.

I have searched for solutions but they all seem to deal with IMAP, not POP. I have found the folder (appdata\profiles etc) where the sent file exists, and it's there and very big. I tried copying it to a new name ("sent2") and asking Tbird to store sent messages there but it's still empty and not saving messages. I also tried deleting the sent.msf file and that didn't help either.

Any thoughts?

Gmail and MS Exchange SMTP servers time out

I am long time user of Thunderbird and currently using version 128.10. I am having trouble downloading and sending email either from Gmail or from my MS Exchange account as of late (May 2025). Email sometimes selectively downloads but I am no longer able to send email either through my Gmail of MS Exchange accounts as both the Gmail and exchange SMTP servers time out. This problem started with the previous versions of Thunderbird circa Nov/Dec 2024. A Thunderbird or Windows update resolves the problem for a short time but then the problem it reoccurs. Server settings are all correct and have been checked multiple times. I've deactivated Norton AV and firewalls, added and/or verified port exceptions but to no effect. This problems has resulted in many overlooked important emails until they've been double checked on webmail portal. Is trouble sending and receiving emails a broader issue with Thunderbird users and are Google and Microsoft deliberately making it difficult to use Thunderbird as an email client? I've seen older posts dating to 2023 reporting similar problems and I'm surprised that without changing anything on my end that this problem suddenly popped up. Any suggestions on how to resolve?

Hello Frinds!

Please help me find a solution to a fatal Thunderbird crash that erased the Inbox folder and its subfolder structure. All emails have disappeared, and the cause is unknown. Tried "View" but did not help. Didn't find any local program tools to restore the before-crash-state.

Here are the details:

1. The incident happened due to a random, uncontrolled cursor movement in the bottom left corner of the program window using the "drag and drop" feature. There was no clicking involved. Or maybe it was a coincidence: happened when Thunderbird was upgrading.

2. The current version of Thunderbird Portable is:128.10.0esr on Windows 10 Home.

3. As a result of auto backup creation on the day of the crash, the backup was overwritten by the corrupted original.

4. The size of the main folder has not changed, so I believe the files needed for recovery are still available.

Is it possible that this disaster is the result of a version update? So so far, Thunderbird worked seamlessly.

Looking for help. So far, I have not been able to find a solution, including with the assistance of AI. Thank you in advance.

Best, Max

Hey. Every single time I send an email, it fails with the following message: "ErrnoException: isConnected failed: ECO- NNABORTED (Software caused connection abort)" The strange thing is that is always sends the email straight away when I manually navigate to "Outbox" and asks Thunderbird to try sending it again.

Device info: Samsung Galaxy S21 Ultra, Android 15, One UI 7. It has always been like this, even before the new One UI update.
