hi, my emails are set never to delete but they are disappearing after three weeks. If I scroll down today, I can't see any emails before the 16th of September. If I know what I am looking for, the emails appear in the search function. Does anyone know why they are not in the inbox? My settings are set so that emails never delete.

This issue has been confirmed on 140.3.1esr (64-bit).

When adding a new account via IMAPS/SMTPs connection, if it's the first time saving a draft or sending an email, the emails do not move to the Drafts or Sent Items folders as expected. Instead, they move to a newly created folder in the Local Folders. Furthermore, the special folder settings in the account configuration automatically change to point to the Local Folders instead of the connected IMAPs folder.

Testing with Thunderbird 128.14.0esr did not reproduce this issue.

I suspect this issue might stem from a mapping problem with Japanese folder names in the Japanese localization. (e.g., “下書き” as “Drafts”, ‘送信済みトレイ’ as “Sent”, etc...) Alternatively, could this be a change in behavior?

Thank you for your assistance.

Can anyone please help me? I use Thunderbird email and for several weeks now I have been able to receive emails but not to send them. At first outgoing messages were refused with the messages "rejected by outgoing server." The outgoing server is PlusNet. I sought help from PlusNet and after several days they told me the problem was connected with their migrating email business to a third party, but was now solved. For a few hours I was able to send messages, soon reverted to the situation where incoming messages are received but outgoing messages are rejected. This time the rejection messages say "rejected due to internal server error." But surely, PlusNet IS the outgoing server? I give up. and PlusNet is hard to contact, they don't seem to accept emails anyway. So can any other TB user advise me, and am I the only one with this problem? PeterB

Thunderbird 143.0.1

My TBird updated this morning and everything turned to crap...

I have TBird set to check for emails every 15 minutes on 4 accounts. There are also 3 accounts that I monitor and check manually...

As soon as the 143.0.1 update touched home base TBird went ballistic. Withing in seconds of it checking for mail on the four accounts it then started deleting the accounts. Any mail was down loaded then poof!! No mail and No mail account. I had to crash dive my laptop to to stop it. Spent 3 hours trying to recover the emails and accounts and managed to reclaim 3 accounts out of the 4 but lost all the emails... After all that effort I was totally peeved and decided to uninstall TBird and revert to an older version... The icing on the cake TBird wont unistall because the YES button on the TBird Helper window wont activate...

After more than thirty years of supporting Firefox and Thunderbird... You have really dropped the ball with this one... As far as me getting an email when someone answers the thread... Good Luck...

Hello,

I have TB 140.3.1esr (64-bit) running on Windows 11. everything works as expected, I love it!

I can't find anywhere that allows me to change the folder's (on the left) font type/style; right now it's all bold style. I was able to change the size but not the type/style.

Does anyone know how to do that, please?

Thank you

I have been using Thunderbird for a few months and changed my Google Password(even though Im not quite sure if the error wasnt already occuring before that), but now when I go on Thunderbird it gives me a popup window that says "Enter credentials for name@gmail.com on imap.gmail.com". Theres a field for the email-adress, but when I click "Next" theres the following error: "400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

These are the things I tried: Entering the old or new Password. Checked if the config is set to OAuth2 in both incoming and outgoing servers and enabled on Gmail-Account. Deleted and tried to (unsuccessfully) reregister my Thunderbird-Account. The same error pops up when it checks my password after the configuration.

I dont know if the password change is actually the cause, since I think I remember the error message appearing earlier today, before I changed the password, but Im not sure. Also, I have another account linked to my Thunderbird, with no changed credentials, and while there is no similar error message, thunderbird suddenly also has problems connecting to it and asks to retry a few times (3-4) before actually connecting everytime I open it.

I suddenly cannot send e-mails, as an alert appears that says I have to change my message in that what I am sending might be a scam or questionable, which it never is. Also, all of my new e-mails are going to "Archive" and always has gone into my InBox directly, until now. What is going on, and how can I change it?

Dear Thunderbird Support Team,

I am reaching out for assistance with opening .tmp files that originate from Mozilla Thunderbird. These files are approximately 650MB in size and contain copies of my text messages, which I would like to recover.

Unfortunately, I no longer have Mozilla Thunderbird installed, and the .tmp files do not open in any other text editor. I would appreciate any guidance or help in retrieving the contents of these files, as it is crucial for me to access these messages.

Thank you in advance for your help.

I am attempting to set up Thunderbird on my desktop. I sign in and only very old email load. I am not sure how to proceed. Outlook is online only now, I need Thunderbird so that I can scan to email.

I used TB for many years on several computers. Last week, I had to reinstall TB on a Win 11 computer, and tried to migrate my TB profile from the Win 10 computer. However, this is an ongoing problem. After several attempts, I have a TB profile on the Win 11 computer that seems to look OK. However, when I open TB, not all the local folders appear in the TB Local folders menu. I read several discussions and guides from other TB users, and tried the suggested fixes. They did not solve the problem. The Local Folders exist in the profile in the Mail folder. When I open the Local Folders, I can see all my local folders that were copied from the TB profile on the Win 10 computers. These include .mozmsgs and .sbd folders. When scrolling down in the Local Folders, after the .mozmsgs and .sbd folders, I can see pairs of folder names w/o extensions (the open with notepad and contain text) and files with the same names but with .msf extensions.

So, theoretically, all the local folders should show up when opening TB. But they don't.

At this stage, I don't know what to do, and I would appreciate your help.

Thank you.

The new machine is not quick to send a post to junk or trash. I see a message about downloading it before I see it move. Going over settings comparing both, old machine was set to a Pop mail server. The remote helper changed that oh New one to IMAP Mail server. I'm assuming that is the problem but I can't find how to change the new setting from IMAP to POP. There is a red Delete button on the A/C settings page. Should I try that?

Also since I couldn’t use the profile from corrupted old machine I've manually input everything in the new. I have used the Draft files in the old machine as a sort of reminder for me and want to copy it and bring it Into the new machine. Is there a way to do that?

I hope this is concise enough.

Hi, I have tried multiple times to log into my thunderbird account. Every time it says sending login link . I never receive it. Making it impossible for me to access my account

This error message keeps popping up many times a day and is very annoying. I notice that others are getting the same error message but haven't found a fix for it. See image of the whole error message attached.

The weird thing is no matter which of the 3 options I choose it keeps coming back... sometimes within a few second. Also it doesn't prevent me from getting my email. Really odd.  ???

Anyone find a fix yet? Thanks.

Thunderbird just updated itself to a state where I need to do the setup process manually, which always takes a few hours (with networksolutions as the host). How can I continue to work with the previous version until the bug is fixed or I have time to go through the entire complicated process? Thanks in advance, Knut

I was using MS outlook and recently I could not connect. Apparently ATT made a change so that instead of a password you need a Secure email Key. Since I needed to make a change I thought I'd try Thunderbird mail, but I still need the KEY. After a number of efforts with the ATT AI and human support people I could not find where the Key is entered on ATT. Now I know this forum is about Thunderbird and not ATT, but there must be Thunderbird users that have ATT and have made a seccussful connection. There are a few ATT help pages that outline how to do this, but each time I look at my ATT profile I can not find where to enter the Secure Mail Key. Is there anyone that can help me with this? THanks Mike

Hi. I have recently compressed thunderbird which has wiped two servers. I have three pop accounts on thunderbird. I have a functioning email service on the machine that I compressed but another machine and my smartphone have no emails. I have checked on the servers to confirm they have not archived or trashed my emails but everything is gone. How can I reload the servers from my only good copy?
