Logged into Thunderbird this morning. On current version. Noticed that the local trash folder had emails in it. I have not changed any of the multiple account setting. Send some test emails fro 2 accounts and they ended up in the local folder trash. What has happened. I want this redirection to stop. What other demons have been created by the current update. HOW CAN i fix this problem?

When I open Thunderbird it is sending my emails directly to the deleted folder. I have tried all-sorts and cannot find an answer. I transferred Thunderbird to my new PC and all was working okay for a few weeks then all of a sudden there were emails missing from my inboxes and I found them in the deleted folder. I am 76 years old and need an easy step by step solution please ..... John

Thunderbird keeps bringing in emails automatically. I don't want it to download anything until I ask it to. This just started when i had to reinstall Tbird after it stopped working for me. 1. It downloads emails automatically 2. I only want emails upon my specific request. 3. I can no longer find any switch to allow me to turn of auto downloads.

On 3 August, Thunderbird was automatically updated on my Mac Mini to Version 155.0. Ever since, all incoming mail is placed in a folder called Satellite Radio, and distribution to the proper mailboxes stops.

This problem happened after the September update. No changes to any message filters. I am not the only one having this problem. What changed in the update that could have caused this problem? I have had to delete the problem account from Thunderbird because every time I move the messages back to the Inbox in Outlook, Thunderbird would move them back to Delete.

Thunderbird stopped receiving new messages on 02/09/26. I've tried all the help solutions several times and still nothing. I am at a loss. I can send emails, but have to go to virginmedia to see new messages.

When in troubleshoot mode it seems to work better but I do not see anything to disable. After I log into this account without thunderbird all the missing emails come over.

Does troubleshoot mode affect just the one account or all my accounts. If just the one I can leave it in that mode permanently unless you think that will cause a problem. This is only been happening recently to the best of my knowledge unless I was unaware of the problem .

The account in question is optonline.net

hi, in the last few days i have been having issues receiving emails from btinternet.com but only to my inbox (other folders are updating) i am getting the error message The current operation on 'Inbox' did not succeed. The mail server for account username@btinternet.com responded: EXPUNGE failed. i have removed the account and re-set it up, i have made sure expunge on exit is disabled, repair does nothing on the inbox, nor does compact etc. i have run out of ideas hy this is happening, so i downloaded bluemail, to see if the problem came from thunderbird itself. it is working fine on there and immediately updated all my mails. with no issues. i have tried deleting the folder 'username'@btinternet.com and the msf files. i need help to figure out why this is happening. i checked the IMAP settings and its all correct and the same as in bluemail. also worth noting i can SEND emails no problem too from that account, just not receive them... i have tried to add as many relevent screenshots as i can think of.

My Thunderbird Account was updated by TB on 2 September. Since then all of my new emails go to Trash. Although I've tried the various responses to such questions, I've been unable to change the problem and get my new emails to come into my Inbox. I'd very much like your assistance please. Thank you.

Aloha. I'm helping a friend with setting up a new Windows 11 PC, and cannot get Thunderbird to connect to Spectrum's servers. I spent an hour on the phone with Spectrum support and they just gave up and said it must be an issue with Thunderbird. Here are the details:

- Brand new Dell 24 All-in-One EC24250 - Windows 11 25H2 plus all additional fixes. - All Dell drivers updated. - Thunderbird V155.0 64-bit

If I click on 'Get Messages' after a while I get: "Connection to server mail.twc.com timed out". I've gone into the config editor and changed mailnews.tcptimeout from 100 to 500 and still get the error.

In the Account Settings | Server Settings | Test server connection I get: An error occurred connecting to mail.twc.com:993.

I've tried this with both setting up a brand new account in Thunderbird, and also via copying the 'Thunderbird' folder from %appdata%\roaming from her old machine.

Email configuration (from Spectrum).

IMAP Settings Server name: mail.twc.com Port: 993 user name: abcd@hawaii.rr.com Connection Security: SSL/TLS Authentication method: Normal password

SMTP settings Server Name: mail.twc.com Port 587 Connection Security: STARTTLS Authentication method: Normal password

Can anyone help me troubleshoot this scenario?

I have a problem to add my mail account on Soverin.com to Thunderbird under Linux Mint. If I have created the additional e-mail in Thunderbird and I put there a right passord it is not possible to connect Soverin server.

After changing the password in a browser (Mac), only emails from August 9th repopulate (5 of them from different senders). There were about 25 of each email piled up and that is why I changed the password. I deleted all of them, changed password again a week later; but only those 5 same August 9th emails populate again. When I updated and restarted third after changing yahoo password, it took me to the yahoo webpage asking permission for third to access mail and I agreed. Not sure if there is some setting to change in Tbird?

Hi!

Trying to add new account on latest Thunderbird instillation, added information/configuration what I use on another computer and in the end it says: Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nslOService.newURI]

Checked 10x for typing errors and it says same error. These account settings works great on previous versions wihtout Account Hub

How can I solve this?

Best regards,

I've been using Thunderbird on Windows 10 since last year sometime. Currently I'm on version 151.0.1.

I've 4 x mailboxes here and since yesterday, 3 of them show me an unusual message when checking for emails. I tried attaching a screenshot but although the screenshot uploaded, I couldn't find a way to insert it here. But the message says Unable to write the email to the mailbox and asks me to check if I've write privileges (which I have) and to cheek the available disk space.(currently 101GB free).

The message is happening 2 or 3 times each day and lasts for about half an hour, then everything works fine again. Has anyone else seen this??

When sending a message, the email reaches the recipient but is not saved in the sender’s account. This email is not displayed anywhere — neither in the web version nor in Thunderbird. Please help resolve the issue.

Thunderbird has always had a problem with filtering all incoming mail to the correct folders. Sometimes it does it correctly and sometimes it doesn't. But this morning it is dumping all my incoming mail into a folder that isn't the Incoming mail folder.

How do I get it to put the incoming mail in the Incoming folder?

As of September 3, 2026 all my new emails are going into a random folder instead of the inbox. This is also happening on my wife's PC plus and we are not getting the emails to our iPhones until we get out of Thunderbird. What has changed? This has not happened before.
