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.

Dear team

I am facing a strange problem while replying or forwarding the email using Thunderbird. It always seeps displaying sending message box. However, the message is actually sent by the Thunderbird. When I cancel, after several trials, the message box will go. Pl help. I am having this problem since version 115 and presently I am on Version 136.0 64 bit.

Screenshot is enclosed for ready reference. I have done clean installation also but the problem remains. Pl help.

I've setup a filter rule to auto-reply to emails while I am on holidays and this works well. However, there are some businesses who will continue to have me on a cc list or in a team distribution list.

The idea is to only send an out of office reply once. I think Outlook does that from memory.

Is there a way to do it in Thunderbird or is this currently not do-able within the Thunderbird base product or via extension/addon?

Running Version 138.0.1 64bit.

When I downloaded Thunderbird, all the folders from my e-mail account downloaded; but, I could not move a message from the Inbox to a folder. Today, when I opened Thunderbird, all my folders disappeared. Please advise. Thanks, Dan

I have sent pictures from my phone to two people and asked them to send them back, The email with the pictures dosent appear in my email. I can send and receive email from both people, just not the ones with the pictures.

Hello,

This morning, I am unable to access any of my labels and folders. One solution I thought of was signing out and signing back in to see if it would resolve the issue. However, I am afraid that if I sign-out, will I lose my labels/folders created in Thunderbird? What would you suggest?

Receiving this error a couple times a day when using Thunderbird: "The folder 'Inbox' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I can delete some emails but for the most part, everything in the Inbox cannot be deleted. I have looked at other forums but I haven't found a concrete set of steps to get this error fixed. I am not very familiar with the inner workings of Thunderbird, so more details on how exactly to get this fixed if possible would be appreciated.

So, all of a sudden my incoming emails went directly to the "Junk" folder for no apparent reason. When I go to the Junk folder to view my emails, they don't show up in the right viewing column.

And when I try to send them back to my "Inbox," they don't go there and I have no idea where they go. I can't see them anywhere. I've checked my outgoing settings and they're where they are supposed to be....as well as my incoming server settings. They are where they should be. I use Comcast, and have checked with them, and those settings are correct

So at this point I have no idea what to do, and obviously need help from someone much more knowledgeable then me! Hopefully I've explained the issue clearly, and have made it easier for those of you out there. I'm not a computer dummy....but this has be quite baffled, as it came on suddenly, and had weird characteristics.

Thanks to all,

Michael...

The related link in Tasks does not open the corresponding email. Normally, upon clicking the link, it would open the email corresponding to the task I created but for some strange reason it stopped working.

I tried reinstalling Thunderbird but that has not helped. link text

Whenever I send an email from my [email protected] account, it automatically shows up with a logo alongside clearly taken from a notification from Jet2 about. flight booking! How do I get rid of this.

Since a couple of days I have a problem with Thunderbird. I can send normal emails without attachments and I have no problem, but when I attach, it keeps loading in 12%, as if it was checking the files, and from there it doesn't go beyond that until it gives a timeout error. I have tried with another email client and it has worked without problem from the same computer. I have paused the antivirus protection in case that was the problem, but it hasn't been the case.

Dear Mozilla volunteer,

I tried to attach a file created in MS Word 365 to an outgoing Thunderbird email message on a desktop computer running Windows 11. An error message immediately said "file not implemented", and it would not accept this message as an attachment. I asked Google how to implement this file, and its reply was a completely inscrutable AI-generated set of instructions readable only by a professionally trained IT expert (if indeed such a person even could read it).

My question to you is: How do I "implement" a file so that Thunderbird will accept it as an attachment? OR: Can you modify Thunderbird somehow so that "implementation" is not required?

Thank you for considering this question.

For weeks I've been struggling with emails coming in only every couple of days. I've been struggling with your Thunderbird option, probably causing even more problems. Can someone step in and solve this??

I have a second email source which has been working. It's [email protected] . My first account which has the problem is [email protected] . My provider has set up my two emails so the [email protected] rides on the [email protected]. Aerohost.com that operates these two says this is not caused by them.

What can I do to solve this????

Thunderbird is set as my default email client on my desktop Windows 10 in the default apps and it's set in the Default Programs control panel but when I try to send a document on my desktop to mail recipient, a message comes up saying there is no email program associated to perform the requested action. It is set in Thunderbird as well as the default mail client. Cortana is no longer accessible on Windows 10 on my pc. Thunderbird is set as the email client in the registry settings, I have only a few Startup programs running on startup and cleared the cache in Thunderbird so I don't know what else to do to fix this?
