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

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?

When I returned from a 20-day vacation, I had a message that “Thunderbird had a problem and crashed. We’ll try to restore your tabs and windows when it restarts….” I do not know when the “crash” happened. However, I have had problems with my 5 AOL email accounts and sometimes the 3 GMAIL accounts since August 20. The AOL accounts are the worst problems. Emails from one account are coming through under a different email account. This is happening with two accounts. Emails for one of the accounts is not coming through at all. I can read messages; but I cannot send any messages through any AOL account. Sending messages through the GMAIL accounts is sporadic in going through. Although my husband and I have separately checked all TB menu items, tools, & settings, we have not found the answer to correct my problems. Any help is appreciated.

Hello,

When I start a new message, it's always shown 'Copy message to'. This has suddenly disappeared. (It puts copies into 'Sent'). I have 3 accounts set up; this seems to happen with all of them. I've probably clicked om something unusual, without noticing it. How can I get 'Copy message to' back again, please? Any suggestions? (I've tried clicking on things in Account Settings, without success.)

I see I've had a message from Mozilla saying 'Use 618307 to sign in'. I've been able to sign in and create thus message anyway. Is that normal, please?

Thanks for your help -- it's needed and appreciated.

All good wishes,

Roger Fern.

I like to know what is the problem at my e-mail setting? Since two weeks ago, when I sent a message, receiver could get my message, but there were no sent record in my Sent Message box.

This is probably not a T-bird question, per se, but it is so strange it seems that this might be the best place to start, hoping someone might have some insight.

My wife and I each have our own laptops, running Win-11 Pro. Each laptop has T-bird 153.2.0esr (32-bit). We each have an account to yahoo mail (the site now hosting our Comcast email accounts). No problems since ... forever. Until today.

Now, beginning today, on my wife's laptop, when she opens T-bird, she gets a pop-up logon page, pre-loaded with her userid/email address. No input field for a password, but that it not unusual, as a lot of sites put that on a follow-up. But when we click 'next', it just rejects it. We were able to log into the yahoo mail web page (in Firefox) just fine.

After a lot of head scratching, I added her account to the T-bird configuration on my laptop. First time up, it prompted for credentials, but here it accepted them. So now we have her yahoo/comcast account configured and working just fine on my laptop, but continue to get credentials rejected running the same config on hers. Again, this has been working just fine up until today.

(If you are wondering about the connection between Comcast and Yahoo, several years ago we 'cut the cable' with Comcast, after confirming they would continue to support our email accounts. Then some time ago, they off-loaded that to Yahoo, such that we were able to retain our Comcast email address, but it redirected to and is hosted on Yahoo.)

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.

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.

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.

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??

Hello everyone,

Environment: Thunderbird 155.0 Windows 11 Pro, Surfshark VPN and Bitdefender Total Yahoo.ca POP3 account transaction@notice.aliexpress.com promotion@aliexpress.com

The Symptoms: Thunderbird stopped downloading emails from my yahoo.ca account with the message "Downloading message 1 of xx" where xx was increasing from one day to the next.

What I Have Tried: I disabled the antivirus and VPN without any result. I deleted the file global-messages-db.sqlite without any result. I entered the web interface in my yahoo.ca account and I saw that after the last message downloaded in Thunderbird there was a message from <transaction@notice.aliexpress.com>. I deleted the message from <transaction@notice.aliexpress.com>, restarted thunderbird and it started downloading messages until the next email from <transaction@notice.aliexpress.com>. I repeated the procedure several times with the same results: Thunderbird downloads any message except messages from <transaction@notice.aliexpress.com>. Other messages from aliexpress.com (e.g. promotion@aliexpress.com) were downloaded without any problems. The message download is blocked only when an email from <transaction@notice.aliexpress.com> is reached.

I searched for solutions on the internet but I didn't find anything.

I have successfully used Thunderbird to receive my Earthlink emails up until today. I check on webmail and see many new emails but they do not download to my Thunderbird application. I've changed nothing. Was there some change at Thunderbird? What to do to fix this?

Hello,

Recently, the manual message check feature has stopped working, whether I use the “Get Messages” button or the menu.

When this feature was still working, I could see the progress of the message retrieval from the server in the status bar; now nothing happens (no display in the status bar and no messages are retrieved).

I should note that this isn’t a connection issue, since new messages are successfully retrieved during periodic checks or when Thunderbird starts up.

Has anyone else encountered this problem?

Thanks!

I have just downloaded Thunderbird on my Samsung mobile. Incoming emails are not displaying in Inbox. I have tried turning sync off and push on and it still won't work. The only way is to manually sync

TB is sending most of my email to the wrong folder. I had 21 message filters, but then I noticed that a lot of things were going to a folder named "bridge" for no apparent reason. I looked at the filter log, but there was nothing in the log for the last few months.

I did have a filter sending certain messages to the "bridge" folder, but TB is sending things there for no reason. I disabled all 21 message filters, and it is still doing it.

I have version 155.0 and I'm using Windows 11 25H2.

How can this be fixed?

Thunderbird has stopped getting messages and 'get messages' doesn't work & I have to close & restart thunderbird to receive them. Nothing has changed with the email client itself.

I know messages have arrived by checking my providers phone app, but for Thunderbird to download them to my PC I now have to restart Thunderbird to get new messages

I use IMAP to grab my mail, if that's important.

In the last couple of days, my normal method of deleting messages from my Inbox, right-clicking on the message and selecting the trash can icon, has stopped working: the message disappears for a moment, then reappears. I can delete it by dragging it to the Trash folder in the folders pane on the left.

I've followed the instructions given in several postings here, including deleting the Trash and trash.msf files, doing that and then creating an empty txt file called Trash (no .txt), and using Repair Folder.

It just now occurred to me to disconnect from the Internet and try to delete a message. It worked fine?!

After fixing the view problem of my email in Thunderbird (thanks for the F8 tip!), my email stopped downloading. I have no "prompt for password" checked. There isn't a primary password checked. I've confirmed the pop outgoing email is correct with the email provider (google). I can get into it without any issues and see my emails there.

I've re-entered the password for the pop outgoing email to no avail.

I use thunderbird and see emails and content in preview line, but when I open the mail it is empty I don't see anything. All emails are the same. I erase Cache and Clear Data from the App Storage. After that all email are fine but when I receve a nea one is the same: empty. Thunderbird 22.0 on Samsung Galaxy A56G, Android Version 16.
