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?

My (our) ISP started using new 'bigger/better' software. grrr

The ISP's tech support had me close (? delete ?) my Thunderbird e-mail account & start a new one.

I cannot access - use any of the ?17-19? folders. How do I, if I can, recover the folders so I can start moving relevant messages to them?

Good luck, remain WELL & be SAFE!

THANKS!

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 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 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).

My gmail account in Thunderbird has only two folders, the Inbox and the Drafts folder. so when I delete a message, it lines out the message in the inbox with a single line strikeout and then in order to get it out of the Inbox I have to leave the Inbox and then when I come back to it the message is actually gone from the inbox. When I am using my laptop rather than my desktop computer, all of the folders are there and the messages, when deleted go to the "Trash" folder and are removed from the Inbox. I have been looking for a way to get all of those folders that are normally a part of the other accounts that I have on Thunderbird without success. Is there anyone here that knows how to restore those additional folders to the Gmail account that does not currently display them?

Help me retrieve my inbox and its subfolders. I have used Thunderbird for 9 or 10 years or more. I know how to find Users and the thunderbird profiles but I cannot figure out what to do next. This is a disaster for me because earthlink doesn't save my old messages.

My computer (Surfacepro 6) crashed shortly before this happened. Thunderbird seems to have updated itself at some point while this was happening and suddenly it was asking me to log in. I didn't know whether to imap or pop. I should have stopped there and gotten help, but i was so bewildered that moments before I was writing emails and several minutes later - poof.

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

Just opened TB. There were 8 or 10 emails. Went to another app for a few seconds. Went back to TB. Emails were gone. Have NO idea what happened. Know of any way to get them back or where they went?

Using Unified Folders option. Not sure what all the folders in the list represent, but these two SENT folders don't seem to be syncing. Why are these files diaplayed (> dalewebb1@Outlook.com and subfolders). Should the stuff they contain be in the UNIFIED folders? As usual, I'm confused. Thanks,

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!

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"
