The tree I made for LOCAL/SUBFOLDERS...is now IN A CRAZY .mst unreadable computer language. I need all the files contained in this tree to go back to readable. Gerry

I have spent 3 hours trying to figure this out. Nothing works for me.

Authentication always fails yet when I log into Outlook it always works.

I turned off using the new hub and was able to setup my email account but it told me OWL was not active (or something about OWL).

Godaddy is my provider.

What am I not doing correctly?

I often categorize my mail in differents files and subfolders. This morning I was checking my mail when I discovered that the subfolder "Agile Retraite' under the file called "Retraite" had diseapeared completely from thunderbird. Could you tell me how to get it back ?

I must have hit the wrong key using a message and all of a sudden Thunderbird has renamed my All Mail folder to Archives. I have spent a large number of hours trying to self-help, but alas, I am at my wits end. At this point in time I have two folders named Archives, one with all my messages and one that is empty. I even uninstalled and downloaded Thunderbird onto my Windows 11 desktop PC. Anyone care to help an old IT software developer? My objective it to somehow get back to having only one All Mail folder

Thanks, Brad

I was working with thunderbird today. Was in a specific email folder I had named "reference" that I use to store various emails, probably around 50 emails in there. Suddenly they all deleted from the folder as I was watching the screen. Checked spam/trash folders and nothing. Also logged into my webmail provider and nothing there either. Any idea what could have happened here? They just seem to have literally vanished. Have used Thunderbird a number of years and never experienced anything like this.

I made a folder and saved emails in that folder. A few days later they were all gone, empty folder. I followed suggestions on here, did the repair, erased password and replaced it, did the subscribe, and now even the folder is gone. I spent hours trying to research this and repair it and now I have nothing.

I apologize for the unhelpful summary line, but I am totally new to Thunderbird and the Unified Inbox is acting so strangely that I don't have any simple way to describe it.

Many (but not all) of the emails are displayed twice in the list of messages.

When I delete a message that isn't doubled, the message disappears from the inbox (as it should).

But when I delete one of the doubled messages ONE disappears as it should and on the other Thunderbird clears the From and Subject fields and changes the date to 12/31/1969, 19:00 -- the changed entry stays in the list and the body of the email is still shown in the lower pane. The only way I can get rid of the message is by selecting another folder (ANY other folder) then when I return to the Unified Inbox the deleted messages will be gone from the list.

I can't believe that this is how Thunderbird is supposed to work, so I assume I have something configured incorrectly (although nearly everything is still at the defaults that the installation gave me).

Starting in mid November 2025, my subfolder - named Apps, disappeared from my folder structure. I've used this for many years without an incident. It remains on my structure when I open my email via a web browser, but is absent from Thunderbird.

What changed? Is there something now forbidden about the name?

As I have message filters created to sort all my emails, it is a real problem now with Thunderbird. I would be grateful if someone can enlighten me on how to solve this issue. Jerry

Please help me to return to normal.all my emails appear in several placs. If I could the get back to to the first download I willl be happy. as you probably see I am not a computer person Please if you could help many thanks

I have a set of e-mails that I am unable to delete or move - when i try they disappear for a few seconds and then re-appear. They all contain a red bold warning "Caution external e-mail"

This has been happening for a long long time - probably a few years' worth of versions. I have just put up with it... currently running Tbird 147 and it just happened.

When editing an email (either the body or the Subject), if you use the backspace button (the one that deletes to the left) to delete some text sometimes the cursor will incorrectly be positioned about 5 or 6 characters further left than it should.

For example, if I had the text: "Quick brown fox jumps over the moon"

If I were to highlight "fox" in the above example, and hit backspace, I would expect the cursor to end up positioned between the remaining spaces after 'brown' ( pipe symbol here is meant to represent the cursor position): "brown | jumps"

But instead what happens is that the cursor ends up somewhere among/before the word "brown". It's always further left than it should be, by 5 or 6 characters.

I believe it only happens when highlighting multiple characters and then hitting backspace. It may be more (only?) prevalent when editing/replying to an existing email. (But I'm still only editing the new portions that I add at the top of the email; I'm almost never editing in amongst the original quoted email content.)

I also haven't ever been able to figure out how to make it happen, sorry. It is just random...It will happen once in an email, but then not again. But it happens frequently - 3-6 times a day perhaps. (Depends on how many emails I am editing.  :) )

I don't believe that I have noticed this issue if I were using the Delete button (deletes things to the right). I don't think it happens when backspacing one character at a time...but it might. I also use Option-Backspace to delete whole words at a time (instead of highlighting the word); not exactly sure if it happens only if highlighting a word, or only if Option-Backspace, or single key press... sorry, it is so random and unexpected that I don't have more specifics.

I've lost all the contents of a folder in one of my TB accounts, including all subfolders. Mysterious, and all the more so since another email folder which wasn't a subfolder of this one is now in there as a subfolder. Everything else in that folder has gone. Nothing has disappeared anywhere else. I've trashed and rebuilt global-messages-db.sqlite but this hasn't helped, no difference. Any suggestions? Thanks!

My emails sent folder has 485 messages. Is there a way to delete them all at once instead of individually?

Also how do you check for new email if you're in the program. I have been shutting Thunderbird down and then opening it back up. Is there another way of doing this?

I was not receiving emails from a Comcast.net email account. I called Best Buy and they used remote access to fix the problem. That fix included deleting and reinstalling the email account. After hanging up with their tech, I notices that dozens of folders and thousands of emails from the last 12 years were gone. I called the Geek Squad back and they could not solve the problem. Are the missing emails still on my computer somewhere? If not, can Comcast recover them? Please help!

Hi! Since I've installed Thunderbird on my new computer with Windows 11, I've now twice experienced the disappearance from my inbox of a bunch of emails. Never had this before with Thunderbird. Could it be something needs doing in Settings (I couldn't find any relevant options)? The emails weren't among the newest, but they were all important.
