Thunderbird Community Forum

I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them. So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email. I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

I started getting this problem about 6 months ago. I have used Thunderbird on Linux for years with very few problems until about 6 months ago. What happens is that when I send a message I get a dialog box saying sending and it will hang there for a long time, sometimes permanently. The size of message doesnt matter. Sometimes I can click on cancel and then retry and I am sometimes told it was sent but not saved. Sometimes it did not get sent at all. It is getting more and more annoying. It seems to happen after long periods of inactivity. Its not DNS, I have changed settings and DNS servers make no difference. I even went through and deleted lots of email and still it persists. I am running no extensions.

I have just acquired a replacement PC and installed Thunderbird, and (as happened on previous occasions) I am unable to send emails because the outgoing server settings that were automatically detected are incorrect, and even feeding in those I recorded on the last occasion does not work. I have had a long conversation with somebody at Plusnet Help Desk, who agrees that the outgoing server should be mail.care4free.net and the port number should be 25, and the connection type should be SSL. He also thought that on my "Account settings" screen there should be an option "Account actions" through which I may be able to solve the problem, but this is not there. I think that last time I had this problem, some genius on this forum managed to solve it, and hope that this will again be the case!

Suppose I see 10 incoming emails on my server (core.com). In thunderbird, when I click to download them, I see a message saying something like "downlaoding 10 emails". After that only 2 or 3 of them have been downloaded, the rest deleted. Help! This started happening a couple of weeks ago. I have tried downloading and re-installing Thunderbird, to no avail. Should I change my account settings?

I have Thunderbird with the same email box on my computer, laptop (both Windows 11) and mobile phone. Starting this morning, any new messages stopped coming to the laptop and computer, only to my Android mobile phone. I have checked all the email settings but there is nothing wrong

I have two Yahoo email addresses 0 d6a.... and den2....

Both are set up in Thunderbird

However, in Thunderbird, both addresses show the email/folder data associated with the den2... address!

No emails for the d6a... address load to Thunderbird.

Separate data appears for each email address on the Yahoo web pages.

I used to have Windows 10 and was using Thunderbird with Quickbooks POS 18 and if I wanted to send an email in Quickbooks like a purchase order or receipt, it would open up a mailto window in Thunderbird with no issue. I've moved to a Windows 11 computer with the same profile running a 32bit version of Thunderbird, set as my Windows default mail client, even in the registry I've set it there but Quickbooks says I don't have a default email client setup. I've exhausted every search over the internet trying to fix it. Any ideas?

Changing color of the text during composing an email does not work when I use "Choose a color" button. The color in the button changes, but when I click "Ok" the color does not change. The color change works though if: I click "Last-picked color", or when I type color name "Green" or HTML hex, and subsequently click "OK".

How to change the color of text in a composed email when

I am using Thuderbird on macOS.

When trying to run in Safe Mode, and compose a new message, I the Thunderbird stucks, so I cannot confirm in Safe Mode, but I had this issue in the past also on other machines/Thunderbird instances, so maybe someone else had a similar problem, or maybe it is a known issue, already in dev team logs.

v147.0.1 (64bit) = latest I create a template. Template used by "send a new e-mail from template" works fine and send with text and pictures. All Good.

I use a Filter that sends an auto-reply from a Template. Sent message have wrong coding (Poland chars are replace to some strange characters) and no picture in it, at bottom of e-mail are some codes.

Seams of BUG in Thunderbird, a many years ago was z bugzilla for Mozilla products, now I found only that forum.

Given Thunderbird version 140.7.1 esr (32 Bit)

Since 27.01.26, no emails have been downloaded from my ISP Server and I don't know how to fix.

Note in the version above, it says (32 Bit) but Windows 11 is exclusively 64 bit ????

Not so much a question as an answer, but I don't have the time to get organised as a contributor. Every so often I get an email which presents as html code instead of the correct email, and I know from experience that the fix for a corrupted folder can take a long time to fully reload. The following fix for an INDIVIDUAL email works on Microsoft servers (outlook, hotmail, msn etc): 1 - note the date and time of the corrupted email 2 - using a browser log directly into your email service 3 - create folder, you could call it "repair" (if you haven't already done so) 4 - find the email in the inbox (the date and time will help) 5 - assuming the email on the server is OK, right-click and move it to the repair folder 6 - go back to Thunderbird, you should now have a repair folder containing the (hopefully uncorrupted) email (you might have to wait for it) 7 - right-click the email and move it to the inbox - it should replace the corrupted email.

So, from time to time I need to find a sent email, it is not in my sent folder, I check my settings and there it is, I then set it to use my sent folder on the IMAP server, this works for a while, but then seems the next time I want to find something in the sent folder it has reverted back. Any Thoughts?

Recently I notice if I forward an email to someone or I send an email with an attachement it is failing. Sometime I get a bounce email hours after or none at all

What am I doing wrong?

Something changed, but I don't know what. I can not receive nor send emails on my PC Spectrum email account. I can receive and send them on my iPhone and iPad. I've changed the configurations, but no luck. I'm using the password saved on my iPhone to log into Spectrum/Charter.net Any suggestions? Thank you!

This is what I get when I click on email link. I can't delete it. This has to be solved before I can get to my second problem https://webmail.spectrum.net/mail? context_token=eyJza3NpZCI6ImNvbnRleHRfdG9rZW5fc2lnbl9rZXlzZXQiLCJza2lkIjoiNmJkYzZiMTEtZjBiZS00ZGFlLTliOWUtY2RkMGMyNWE5ZmUyXzIwMjAtMDEtMjRUMDcuNDIuNDQuMzQwWiIsInNlY3BvbCI6ImNvbnRleHRfdG9rZW4iLCJraWQiOiI2YmRjNmIxMS1mMGJlLTRkYWUtOWI5ZS1jZGQwYzI1YTlmZTJfMjAyMC0wMS0yNFQwNy40Mi40NC4zNDBaIiwia2V5VHlwZSI6IlJTQSIsImFsZyI6IlJTMjU2IiwianRpIjoiYWU2MzMwZDYtNTBlZi00Mjk3LThlOTMtZDUxOWVjZmMxMjdkIn0.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.SkxhnFtRLxHTpXXn5_kDX8nBISuPu3wdpoNFwTKLtmUadL29D40rNMHlmEOOa2LbGFVi8qlEWnscUMV8WXGLF02RFhSsEMFtBbXGpB9XUy6q_YW5FRJo1su5AJxboh1LMastJ39rdqnooQsnvA5_Mmy4NDBZrb1bQCmzXn3wiLsiBDMxorQ8Kk45CEWL6Bz09Z8EltuEQ2yVN3FGTGqAeU2i5-qNv12kzgimIu4TbDyE2DIi6_AKenLGc1kXlcZ8oxGjUEbJm1AThmpNbGF9WJ7d55_JQyfGWvEMIYNOtAiPaNNRCF1AlcBP3TAH34L1uI49Ve6C0SvidbRu2jYDuQ&referrerAppVisitId=202601311716P-753ab3c2-c22c-44cd-865d-2b77307fabfa&referrerAppName=SpecNet&referrerAppType=Web

Neither plain-text nor HTML-signatures are being removed in replies, even though they are at the bottom of the email i'm replying to, prepended by the default -- tag on a dedicated line, as is the standard. I double checked that mail.strip_sig_on_reply is set to true. This happens on two separate accounts configured on my client. Thunderbird Version 140.6.0esr on Tuxedo OS (equivalent to Ubuntu 24.04)

Hello, I am trying to send and email with script and 2 photos but every time I try to send it I get a very quick flash of a small box with writing in it but it disappears right away, and my email is not sent. Why is this happening and how can I correct it so my email will actually be sent?

Thank you for any help you can provide.

Jean.

Can anyone please explain why, when I type an email and use Bold, Underline, paragraphs etc the program actually changes some text to symbols like asterisks & underscore symbol instead of underline etc that I did not enter and in general makes the body of the email look terrible when it is sent and printed out. I have tried typing the message in Word first and then copying to the email but it still seems to change it when the email is sent. Does anyone know why and can this be fixed? The last couple of emails I have had to prepare in Word, save as pdf documents and then send as attachments and this is a long and tedious process just to send an email message even if it is a long message. Thank you.
