I have been trying to delete a large number of unwanted emails in my All Mail folder. However, once I delete them they are restored. How can I clean up this folder permanently?

Hello, I can receive email messages but unable to send them out. The error message I get follows:

The mail server responded,( bettyweber@shaw.ca sender) rejected AUP#POL. Verify your email address is correct in account settings.

What can I do to fix this in Thunderbird?

I checked with my service provider and I can receive and send messages through webmail but not Thunderbird.

Thanks. Betty

I cannot access my email on my computer or send out email since the latest update. I seem to be offline. Is it because my operating system old? Please tell me what I need to know to fix this problem. Thank you for your assistance.

For many years, I have used Thunderbird and have made a signature in HTML, with clear pathways to loctions where images are stored. Never had a problem. Here is my successful code:

duplicate of /questions/1553385 thread in Thunderbird for Android section

Thunderbird app on Android suddenly stopped moving emails; instead just repopulated inbox. Uninstalled and reinstalled app; added email account and proper password. TB locked into "Checking incoming server settings" loop. Comcast properly set up; accessible from browser. Tried entering settings manually; same result. Cleared cache and data; same result.

Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!

Hi, I dont know what setting I have accidently changed but before I used to double click a new message in my inbox on local folders and now instead of reading it full screen now it wants to send it as an email message to someone!

Any ideas to put it back to just read the email and not compose a message with it?

Thanks.

I dont remember having this 'new message template' thing before when I right clicked on a message in my inbox , maybe thats what the issue is?

I have had Thunderbird on my HP laptop for several years. Everything has worked perfectly. BUT, I cannot receive Email, starting yesterday. When I click the Get Email icon, nothing happens. My Email server on Comcast is getting Email which I can see and read, but Thunderbird is not getting the Email. I would appreciate any advice.

Regards, Jim

Hi,

On Thunderbird 140.4.0esr (64-bit) and on 144.0.1 (64-bit) both WIN11 I have this problem since yesterday:

New message Signature is shown

I add the To: To: xyz@com.com

Signature disappears, mail is sent and received without signature

The signature which I use "since many years" is HTML

As you know there has been an update on WIN11 yesterday...

Any hints?

Thanks for your time

Bob

This just started happening a couple of days ago (after I upgraded to TB 140.5.0esr on a Mac, in case that's relevant).

Every time I type the word "address" in an email, TB changes it to my home address.

Anybody know why this started? And what can I do to turn it off?

Thanks Clint

HI just updated to 140.5.0esr (64-bit) Now all I can see is my inbox and deleted. No Sent or any of the other many folders I could see 5 mins ago ☹️. The server has them all though Some help welcomed!

I keep getting the sign in request (photo 1) and when I click the next button I get (photo 2), I have no idea what has changed or what I can do to stop it. I would be grateful of any help.

I've been using Thunderbird to access my Comcast email for two years now, without problems. Except yesterday & today, when I've been unable to send or receive emails, for no apparent reason. Yet, when I connect to my Comcast/Xfinity email via the Comcast browser website, sending and receiving of email works fine. This access problem began yesterday, 10/14/2025.

Same email address I've been using for about 20 years now, and same password. I made no changes to my Thunderbird or Comcast settings. Sending a test email to myself via the Comcast email website works fine. Clicking on the "Get Messages" icon in Thunderbird results in no action whatsoever. Sending a test message to myself in Thunderbird results in about a 40 second delay (usually it's 10 seconds), and then the error message "Login to server smtp.comcast.net with username don-peters@comcast.net failed." It then asks if I want to try again, but if I agree, the same error results. But there is also the option of "Enter new password". Click on that and the same error results, without even asking for a new password. But my password is OK, as evidenced by my Thunderbird settings and being able to log into Comcast browser email.

Yes, I've spent hours on the phone with Comcast on this issue, but they were of no help. One agent claimed that the issue was with Thunderbird, not Comcast, as its webmail worked fine. Two years ago, I had a similar problem I spent hours trying to solve. It turned out the problem then was due to Microsoft Outlook on my PC regularly trying to log into Comcast to ALSO download my email - BUT using the wrong password. Comcast interpreted these multiple failed login attempts as scammer attempts, and blocked ALL email logins from my PC. I fixed the problem by shutting down Outlook. But when I just spoke to Comcast they said the current problem was NOT due to my account getting blocked by them. But they couldn't give a reason for the blockage.

So, I now believe the problem lies with BOTH Thunderbird and Comcast. First of all, Comcast is somehow blocking my Thunderbird access attempts. But Thunderbird is also at fault for not reporting a SPECIFIC email login problem, so that we can address it - and fix it. If Thunderbird can be more specific as to why login attempts are failing, I can get back to them with the evidence - and hopefully solve the problem.

I've been using Thunderbird for about 30 years now, and I hate to give it up. But if this continues, I'll be forced to abandon Thunderbird.

I have tried using the troubleshooting guide suggestions without success. The email is not on the server as verified by webmail, but still resides in my local inbox. Can I manually access the database offline and delete this email? I have two other gmail accounts that are part of my Thunderbird email client version 140.5.0esr (32-bit).

Installed on android phone, imported account configurations using the the bar code method. Gmail accounts all good, but Microsoft accounts all fail. Multiple reinstallations have the same outcome.

The failure occurs at Passkey generation all with the same message "We're unable to complete your request server_error: The contextID supplied in the request did not have a matching cookie" or "Something went wrong trying to create a passkey. Please try again." It uses Brave Browser when doing this.

Any ideas on how to progress?

Thanks

hello, every time i start thunderbird, i'm presented with a tab that shows me the privacy policy. EVERY.SINGLE.TIME. i don't need to read it every time; reading it once and confirming is enough. but there doesn't seem to be any way to confirm, or disable this annoyance. how can i get it to stop? is there a setting somewhere, or registry entry i can change?
