I am using Thunderbird on a Macbook Pro 13-inch mid-2012, in a POP3 account

Thunderbird 140.10 is generally running fine, except that some sub-folders are not visible in my Thunderbird email tool view. I have a hierarchical

I have tried repairing the parent folders, but that had no effect.

The corresponding .sbd files are clearly visible in ~/<user>/Library>/<profile>/Mail/Local Folders/pop-server.<account> and being backed up in Time Machine backups.

Curiously, there is a much-truncated replica of some .sbd folders in Local Folders named /<folder-name>.sbd, all dated in 2013, yet the folder was created in 2017. I presume these refer to an update of Thunderbird that left some trash, and of no consequence. These are parallel to Archives and Archives.msf files.

Please advise on how to disambiguate this structure and recover views of existing mail folders not being displayed.

One of my local folders of email disappeared: it is no longer displayed under Local Folders. A few days ago while using my mouse to move a message into one of the local folders, something happened, a peculiar message briefly displayed. At the time I did <Ctrl>-Z to undo whatever happened, but I didn't see any changes. That must be when the folder disappeared, but I'm not sure.

My other folders are still in place. I can't find the missing folder inside any of the other folders (junk, deleted, archive, etc.). Yet when I search for email in one of the missing folders, the messages are found. When I go into Troubleshooting Information, there is no Profile Directory listed, and when I click on the Open Directory button, nothing happens. (I've gone through the process of transferring Thunderbird accounts to new computers in the past.) I'm using Pop!_OS 22.04 Linux and Thunderbird 140.10.0esr. I backup my laptop using Back In Time. Any idea how can I fix this?

I've tried setting up Thunderbird archiving according to the documentation to save archived messages locally, and in the same hierarchy they had when I archived them. That is, if I have:

INBOX

   Box1
   Box2

... etc. then archiving would create a parallel structure in Local Folders

However, this isn't working.

I select "Keep message archives in Other (Archives on Local Folders).

For "Archive Options" I select "A single folder", "Keep existing folder structure of archived messages" and "Recreate inbox folder".

However, when I archive something, Thunderbird just creates a folder "2026" (this year) and puts the message in there.

Why are my settings NOT working?

I have been using Thunderbird for my email X@plethora.net since 2004. My son set it up. Now I have two additional emails, @mail. com, and I desperately need to be able to read them somewhere with a usable interface. One I had been reading in Apple's Mail app (also for many years, but Google locked me out of both of them on April 10. I have the emails back,, and it has screwed up everything else. I don't want to be stuck forever with https://mail.google.com/mail/u/0/#inbox and https://mail.google.com/mail/u/1/?pli=1#inbox.

I have a MacBook, from 2021 or 22, which needs to be updated

X@plethora.net has one open window, Thunderbird's inbox, and several tabs. Can I open a separate window for Y@gmail.com? I don't think I need to transfer the existing messages.

My iPhone is X, I have an Apple keychain, with a passkey. I wouldn't mind phone calls or texts, but if I'm on a call, I don't know how to switch away (to receive a text) and then get back to the call.

My inbox Sub Folders have disappeared on one computer only (Windows 11) And, only one email account. Apparently the emails they contained are still there but not visible.

Dragging and dropping multiple local folders has worked for quite some time now. But recently (since last week?) I can no longer do that. I am forced to drag single folders. My workflow requires the ability to drag multiple folders often during the day so this is a great inconvenience.

I am currently using V150.0 64 bit on a desktop running Windows 11.

As of April 4 midnight my yahoo account in Thunderbird just stopped receiving incoming pop messages nor can I send. According to Yahoo, it showed that Thunderbird had access. Thunderbird showed how many new messages to download, but then does nothing but hang and time out. I have removed all stored yahoo passwords; I have removed yahoo permissions in yahoo in order to start over. I get the normal log in screens to add permission with oauth2, signed into yahoo account in yahoo and it shows thunderbird has access, yet Thunderbird still can NOT access yahoo mail (download pop or send smpt). YES MY SETTINGS are correct. They haven;t change since before April 4 midnight. I need this account active again. HELP!!! email to X@hotmail.com with Yahoo in the subject line: According to THunderbird, I have version 140.9 esr. when I press check for updates it says I'm up to date. Although the yahoo help page says as of March 2026 version 148. confused. Bill

When bulk selecting and deleting, sometime columns don't match rows. eg: subject doesn't match correspondents (sometime additional random contacts are added to correct correspondant) and message panel may not match highlighted "subject" email.

Been using for years...love the product. But this is a new quirk. I have noticed, when I have done hundreds of bulk deletions, deleted messages will be added back in inbox??

Thanks, Dave Millert, X@aol.com.

I am unable to add my Outlook email account to Thunderbird Desktop. I keep getting an authentication error when entering the Outlook password which I know is correct. Adding my Gmail account was no problem.

Since April 9, 6:14 PM CDT, most folders (e.g., Drafts, Templates, Sent) on my primary laptop in my primary POP email account, [edited]@bdcusa.com, have disappeared; and ALL SUBfolders in my Inbox have disappeared. Over 185,000 emails have vanished overnight!

On my primary laptop, I'm using Thunderbird 149.0.1 (64-bit) on the release update channel, still running 64-bit Windows 10 Professional, and have nothing backed up to the cloud.

Fortunately, on my secondary laptop, I'm using Thunderbird 115.18.0 (32-bit) on the esr update channel, running 32-bit Windows 7 Professional. I say, "fortunately," because ALL folders and emails are still there, so I know they haven't been vaporized!

How do I return all folders and emails for this email account to visibility and access on my primary laptop? Detailed directions appreciated.

So I have Thunderbird set to autosave every 5 mins.

I was drafting an email, where I had written quite a lot of text (as a reply) and for some reason my text went missing and there was no undo in edits

So I quit and went to drafts, nothing there.

I checked and autosave is on for 5 mins.

hit reply again. typed in some text, set a timer for 12 mins, quit.

Again, no save.

So why is "Auto Save ever " x mins not working?

I have tried using both a zip and unzip folders along with a backup folder for moving an export of the calendar. I export file is larger than 2GB and i find no way to make it smaller. or i can not find a way to export a pure csv file. All the above fails on import. please advise

Email older than several weeks in mail subfolders is blank in Thunderbird and looks like binary within buffer D:\WORKSPACE\Computer Tech\Config & Buffers\Thunderbird Stuff\Profiles\dq1ljd8g.default\Mail\Inbox Archive I assume that the mail resembling binary has been compacted, but it appears that Thunderbird cannot un-compact the messages. Need some help, please.

Hello, I have selcted the option "Expunge" under Settings -> Server-Settings -> Message-Storage. The intention was to delete messages from the server of ma Email-Provider (GMX). Unintentionally however, the result was, that instead, the Messages have been deleted from my local computer. Can I recover them? They do not appear in the Recycle Bin.

I am using Version 149.0.2 (64-Bit) on a Windows Computer.

Thank you in advance, Michael Gerkens
