Help! I've been using Thunderbird for 2 years and just discovered that my Local Files only go back 1 year. Being used to Eudora who kept things forever, I am dismayed at this: how can I stop Thunderbird from deleting my important files!?

I have been using Thunderbird for years for email accounts with Comcast (Xfinity), Yahoo, and gmail. Yesterday, I started having a problem with my Comcast accounts - when I sent a message, it went out, but I got an error message (attached) saying it couldn't save a copy to the Sent folder. Sending messages from my Yahoo account works fine. Sending messages from my gmail accounts, I get _two_ copies in the Sent folder (this is new).

I tried restarting my PC, and that didn't help. I tried Troubleshoot Mode, but that didn't help. I tried reinstalling Thunderbird, and that seemed to fix it, but then it started again. I tried compacting the folders, and that seemed to fix it, but then it started again.

I can connect to the Comast/Xfinity server fine, and things work. If I send an email from the server, a copy goes in the Sent file, and it then shows up in the Sent folder on my desktop. But emails that I send from the desktop don't show up in the Sent folder.

I am using a Dell XPS8950 with Windows 11.

Thank you for your help.

I can't seem to get Thunderbird configured correctly to get the "send to" function to work. As in sending a file from the desktop. I checked the default file association, and it looks to be set correctly. Help! And thanks.

since last update my *All Mail* folder is empty but at the top it says there are 138,944 messages. I can use some filters and SOME messages appear but by far not all that should match that filter. any clues? thanks,

Thunderbird 140.6.0esr (aarch64) on a Macintosh using Tahoe 26.1

I was working on my email accounts when the messages in the inbox of one of my email accounts disappeared. The message count on the top left of my inbox display says 0.

How do I get them to show up again.  I am using Thunderbird on Mac OS 15.6.1

All of my previously read emails are still highlighted. The number of "new" emails in the count continues to rise, when I have seen them all. How can I shut that off so I don't think everything is a new unread email?

I have created a series of named folders on my thunderbird home screen and I move incoming messages into each folder according to subject matter. I set up a folder named it BUPA some months ago and moved all incoming emails relevant into this folder. Now I have discovered that this folder does not appear under my list of folders on my home page and it has dissappeared. I do not know how this took place but I assume that this collection must still be on yourserver and if so can be restored to me. I would be most grateful if you could assist me with this problem.

Hi everyone - and big thanks in advance for considering my request: I have/ had windows 11 on my old machine and windows 11 on my new machine; because my 'old computer' is not running anymore at all (liquid damage), I can no longer start Thunderbird and follow the 'export tool function' (https://support.mozilla.org/en-US/kb/thunderbird-export) and thus can only do the manual transfer (https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer); I didn't think that I would need to go through the export tool steps when I saved the Thunderbird profile folder regularly as backup on the cloud; yet when I started Thunderbird on my new machine following the above steps by moving the Thunderbird profile folder manually, the result is that - although Thunderbird is 'running' and the mailbox is functioning properly - the key folders are empty (i.e. the sub-folder structure is completely lost, in fact there are no individual emails at all); the issue seems to be that the size of the Thunderbird profile folder is too large (the "Profiles" folder has a size of 20.5 GB) for doing this transfer via copy & paste of the Thunderbird profile folder from the cloud (I also tried USB) to the new machine; I understand that the size issue via the manual transfer could be 'overcome' just by starting Thunderbird on the 'old machine' and following the above steps explained under mozilla support; yet that's no longer an option; what could I do please?

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

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!

Recently my Thunderbird mail has been 'glitchy'.

Sometimes I receive audible alerts for emails, other times I don't.

Sometimes the number of new emails received is correct, other times it shows 4 new emails when, across all my accounts, the number is 2 (for example).

Are either or both of these known issues?

I also noticed when I was watching a live music stream on TikTok last week, I 'had' no emails for almost 2 hours. As soon as I left TikTok and closed my browser window emails 'arrived', one timestamped 45 minutes earlier. The settings for that account are set to check for emails every 5 minutes.

Could the Chinese be 'watching me' 😁 or is there another more innocent explanation?

Running Thunderbird 140.5.0esr

This has been happening for a few weeks now somewhat randomly. The folders under Mail for one of my accounts keep moving around and are not in alphabetical order anymore. Most folders are OK, but a few either jump to the top of bottom of the list. I can manually drag them back, only for different folders to do it the next time.

The folders in questions are 2 levels down from Mail.

Cannot get rid of TB's request for account password/connection for an account that I removed. Server account deleted, saved passwords for this account deleted. All references to this account that I know about have been removed and still when I open TB it pops up with request for username and password for this deleted account. Please help.
