My 'sent mail' has suddenly all disappeared - although still on the mail file server. Inbox mail is fine - but if I send a test message to myself, I get the reply, but the sent message is not saveb. I have uninstalled and reinstalled Thunderbird twice, n - the second time deleting the Mozilla folder under C:\users and then rebooting This happened whilst I was using Thunderbird. I have used Thunderbird for years without problems I have run a virus scan with Malwarebytes, but no problmes showed up. All folders are still vixible on my iPhone

I am about to try reinstalling again. I don't want to have to change email clients.

Any help much appreciated.. Thank you Joan Kemp

Sent mail has suddenly vanished, even though it is still on the originating file server. This happened very suddenly. I uninstalled and reinstalled Thunderbird, but no change. I am about to reboot PC to see if this will solve the problem. Very strange!

Thunderbird 140.6.0esr (64-bit) "On Linux LMDE 6" 64 bit, on an Intel platform. An HP small format desktop, using two screens.

I see this issue (below) when receiving digest mail from groups.io See the hopefully attached image. If that didnt come through, I can send you a whole screenshot if needed.

The issue is that the first line is correct. The "sender" is the group "linuxham" and is a mail digest message. The second line "Thunderbird 2025: A Year in Review" is correct.

However.. The third line from the UKMicrowaves group, another groups.io group configured to use "Digest Delivery" mode, is shown as coming from "[edited] @groups.io" Misleading at best! (It is always the linuxham group details that is used, regardless of which group has sent the digest.)

The last two lines are correct.

I see this on all groups.io group mail where what comes to me is in the form of a "Digest" (so as not to flood my inbox.) Does T'Bird handle "Digest" mails differently to one-to-one mails?

This odd labeling of the "Correspondents" started some time ago as a result of a past T'Bird update, but prior to that update, was not an issue. I have "Many" groups.io groups I'm a member of.

Sorry but it's taken me this long to find out how to submit this info and ask the question.

I'd love for this to be fixed, and am willing to test any trial version(s) that may be needed, and/or to provide any other needed system info that would help. I am contactable on [edited from public] @googlemail.com

Oh... I made "Many" attempts over the last year or three to setup a "Mozilla" account to report this, but I now know "Mozilla" has renamed to just "Moz". Sadly, "Moz account creds" are not accepted! to login here.

By accident I found that a Google ID works. Pity that was not sorted some time ago, else I could have reported this sooner. (Better presentation on the T'bird support initial web page would help with such confusion, or is this intentional to filter out lame questions? And lower support costs! I know of others who implement such! ;-)

Anyway, thanks for seemingly letting me in at last. Much appreciated from a long time Thunderbird user of "Many years".

Even with the above wrinkle, it's far the best mail client out there I find. True "Cross Platform" too. (Though I found the Android offering rather "clunky" at best.)

Thanks Again.

Yours...

Dave or G8KBV, yes a "Ham"...

Merging an installation I need to move emails from a local folder to my inbox folder and sent box folder. When I try to do this the menus seem to permit it but the emails don't move. Why might that be?

I have three accounts set up in Thunderbird and my "ALL MAIL" folder has disappeared from my GMAIL ACCOUNTS. I did however appear to have 2 x Archive folders but in schofijnet10 one has disappeared in john.schofield10 i have 2 x DRAFT Folders and 2 x Sent folders in schofijnetQaol I have 2 x ARCHIVE and 2 x SPAM Folders Please see the image

Just noticed that I have 2 folders named Sent. One of them is the Trash folder, which has a garbage can icon next to the word "Sent". When I click on properties of the folder it shows the name as Sent and the Location as mailbox://nobody@Local Folders/Trash. I clicked on Repair Folder and that didn't alter the name of the folder. The name "Sent" is read only.

My computer crashed and so restarted it, when went to open thunderbird got a couldn't load XPCom message. Followed directions to reinstall thunderbird without using the uninstaller. When I installed it, I reloaded my email to set it up. I have lost all my latest emails, only getting them from 15 years ago. and today, nothing from this year. All my folders have also gone and my contacts.

Can someone please help, how do I fix it, I have emails from this year that I need to keep.

Starting 2026 Comcast is moving all email over to Yahoo email. We will be able to keep our Comcast email address, but as of this writing I do not know what suffix Yahoo will add to my 2 accounts. Both of my Comcast suffixes are Comcast.net and that is how my email comes through now. I was shared a linked that I didn't from Comcast about the pending change. Will the suffix change from Comcast.net? I have attached the link that was shared with me.

I guess with your Comcast e-mail, you need to know this. Comcast e-mail is going away and users are being switched over to Yahoo e-mail sometime in 2026.

Upgrade your Comcast.net email experience to Yahoo Mail

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 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
