Kinda confused. Why, when I enter the unified folders, is the INBOX show empty when the ALL FOLDERS shows 6, indicating that, indeed, messages SHOULD be there? See attached.

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!

If I use Thunderbird for Android to send or answer an e-mail it will be stored in the folder "Sent". That is correct, but I also receive a 100% copy of the e-mail in my Inbox. I cannot find a setting to switch off this behaviour.

I am using 140.6.0esr (64-bit) and Windows 10. My Inbox disappeared. I was in it with no problems. Then I noticed two problems. I couldn't open new emails. It said connecting to server or loading content but email was blank. Also when I sent an email it could not copy to my sent folder due to network or file access errors. I could open and read all the other emails in my Inbox, just not three new ones. So I selected Inbox properties and repair. After the repair, my inbox is completely empty. It had thousands of messages. When I do a search for common emails I know were in my inbox, it only shows emails from subfolders. When I go to Inbox properties, it says number of messages: 0

Is there any chance I could talk with someone? Or that someone would call me? I'm not experienced in Thunderbird or email settings. And I don't like having to do it online. Richard Higgins Concord Mass

No longer a Spectrum cable user. Been using Firefox/Tbird for years. Will I still be able to use existing (charter.net/Spectrum) email address via Tbird?

This morning when I opened Thunderbird it got all my new messages in inbox but when I went to transfer some to local folders there wasn't any. I probably had about 25 folders in there. I still have email on my older computer and it still works fine. Local folders are still there. What do I do?

Wow, all my sub directories under my email address-s is gone, where did they go all ways made new folders under my email names to save IMPORTANT stuff...

so pissed so pissed..............................

The sorting of the Recent Destinations menu has changed and is now no longer usable. It is not sorted by most recent or any other obvious order. It now takes me more time to scan through the list to find what I want when it used to be a very useful/quick tool. Anyone else notice this new issue? Thanks!

Hello, I recently cleaned up my mail account and deleted obsolete folders on one device. The folder has been deleted on the server, but Thunderbird on another computer still shows the folder. In the subscribe menu the folder is not shown. But when I try to delete it it throws an error "The current command did not succeed. The mail server for account <account name> responded: [NONEXISTENT] unknown source folder.". The error makes sense since the folder has been deleted on the server. Is there a way to tell Thunderbird to just remove this folder?

Thanks in advance!

Today filtering of new emails fails for all folders. The message is "The message could not be filtered to folder <folder> because adding a message to it failed. Verify that the folder is displaying properly or try to repair it from the folder properties."

This is new. No problem filtering message a few days ago.

Lots of free space on my local drive where Thunderbird is installed.

Where are these folders stored? I looked in C:\Program Files\Mozilla Thunderbird but I do not see any such folders there. I looked in C:\ProgramData\Mozilla but nothing there either.

Thank you.

I have a problem with Thunderbird on Kubuntu 24.04.3. The drag and drop of mails from inbox to TB-folders stop working after a while. It always happens when I minimize Thunderbird and maximize again, then the drag and drop has stopped working. I have also seen it if I for instance make a new folder, then it also stops working. It has been going on for a while now, at least the last 3 month. I have automatic update on, so I an running the latest version right now 140.4.0esr (64-bit).

I am using Thunderbird 115.5.2 (64-bit) on an older iMac on OS 10.12. I have four email address accounts, all gmail, and using POP. I have stored emails I wanted to keep in sub folders in Local Folders. This has all worked well for years.

Yesterday I lost lost all content from some of the subfolders in Local Folders, while some retained some content and a few seem intact. I also lost most emails that had arrived in the inboxes in the last week. The folder pane still shows the accounts, with their own set of folders. As usual, the inbox folders are highlighted with the number of new emails downloaded from the Gmail server to each address, but I can not see them in the message pane, or find them anywhere else. I sent a test message from one of my addresses to another – It didn't show as sent in Thunderbird, but did go through the gmail server and the message count of downloaded messages on the recipient address went up by one, but I couldn't see the email. Then I tried clicking on the folder "properties" then 'Repair Folder' but nothing happened, although the information on that window showed the number of messages and MB that I would expect to be in that folder, rather than what was there, which presumably means they may still be in there somewhere? I would be very grateful for help – I'm not tech savvy and feeling completely lost.
