Within the past day or so, which means 7-18-26 or later, some of my email messages on thunderbird for my pc have a "From" description that is not correct. I look at the messages, and the "From" is entirely different than the "From" description when looking at the email message list. I have never encountered this problem before. I'm using thunderbird 152.0.1 64-bit on my pc.

Windooze 11. TBird 152.0 installed on June 20th. Now it seems like TBird is not displaying HTML emails properly. They are displayed but not at the beginning. The first line is sometimes just the bottom half of a sentence in the email (if that makes sense). I can't scroll back to the beginning. If I go to outlook and display the same email it displays fine.

Did something change in 152.0 to cause this?

Thanks, Ed Mazurek

I have several MBOX files with me and I want to import MBOX files into the Thunderbird email client. I've come across different methods, including manual techniques and third-party tools, but I'm unsure which approach is the most efficient, especially when dealing with multiple or large-sized MBOX files. Some methods also seem complicated for users who are not very technical.

Suggest me any reliable tool for this!

I would like to setup Thunderbird as my email client.My email service is provided by Godaddy with an Outlook account. When I am at the incoming server settings, it has my domain name, not smtp.office365.com which I tried with both authentication options (below) and with my domain name, the protocol was IMAP. I changed the port from 143 to 993. I changed security from Autodetect to SSL/TLS. For authentication, there was not an OAuth2 option, I tried Autodetect and Normal password, neither worked. And I used my domain email password. with using my domain name, it came back with an error an suffixed my domain name with :110. It stated that this was not the correct domain and there was a security issue. It is not clear how I should progress.

We are facing issues with Thunderbird mail application.

Incoming emails are not being received in Thunderbird. Thunderbird is running very slowly and frequently becomes unresponsive. Sending and receiving emails is taking a long time. We have already restarted the application and system, but the issue still persists.

Kindly check the mail server settings and Thunderbird configuration from your end and advise on the necessary action to resolve this issue as soon as possible.

Your prompt support will be highly appreciated.

After many years of using Thunderbird I am now considering ditching it. I am continually getting the Authorisation Failure message when trying to open Thunderbird. Why does this keep happening? It does not happen on my Android devices, just on Windows 11. I have tried deleting all three gmail accounts and re entering them. All is fine until I close down Thunderbird and then open it again. I run Norton 360 and have tried taking off Norton email security, but that didn't work. Any ideas, please?

Someone suggested BetterBird would be better for me than Thunderbird, but I'm not sure it was the right decision. They said I should be able to just open Thunderbird and it should work as they have the same base code, but it doesn't. Any ideas? I have 8 email accounts, so I'd hate to start from scratch.

I have an issue when trying to forward an email that contains an attachment. I receive the following error message:

"Sending of the message failed. There was an error attaching the file. Please check that you have access to the file."

I am using Thunderbird version 152 on Windows 10 Pro.

This issue only occurs when forwarding emails with attachments. Other email functions appear to work normally. Has anyone else encountered this issue? I would appreciate any help or suggestions. Thank you in advance.

I have been using Thunderbird on my PC for years and when I got my last PC, I found a article to help me move my files. I am now looking for instructions on how to move my Thunderbird files from the PC to the Mac so I can continue using it as I have been.

Each time I open TBird, I get a message at the bottom left of the screen telling me that TBird has deleted X number of messages. I do not want TBird to ever delete any messages. How do I turn this automatic delete function off?

Hi all!

Years back, I created my first account using POP3 when IMAP storage was expensive. Over the years I added many message filters to organize my tasks. Now I'd like to switch to IMAP and found everything I need, except for how to move/convert/copy my message filters. So my question is how can I transfer my message filters when recreating the account using IMAP? (I have a lot of filters, recreating them is no good option...)

I also noticed, that I have some filters for "Local Folders" and some for my POP3 account. Whats you're recommendation for that? Merge them into a single list assigned to the account? How can I do that?

All of a sudden my emails are permanently staying in bold in my folders, in Settings >Reading & Display Ive tried changing the 'Automatically mark messages as read radio buttons and quit etc and the same issue is happening, please advise

Hello. When handling a large volume of emails, some sent messages are not saved in the Sent folder. As a result, they are only saved on the 3rd or 4th attempt, and the recipient receives 3-4 copies of the same email. What could be causing this issue and how can it be resolved? We reinstalled the client and configured it to save sent emails to a different folder, but all without success.

Trying to send 3 different emails. Hit send and get: 1) Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. 2) Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. 3) Your draft message was not copied to your drafts folder (Drafts) due to network or file access errors. How can I get these problems fixed?

I've used Thunderbird for years. computer crashed and I'm trying to install Thunderbird on my new PC. Thunderbird cannot find account. I've checked with my provider several times and all settings are correct. Any ideas? I've also downloaded installed and uninstalled 5 times today with the same result.
