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.

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.

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?

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?

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.

Good morning,

I’m reaching out because I’m having trouble with my Thunderbird email and need some assistance.

I was using Thunderbird without any issues before, but now all my old emails have disappeared. I can still receive new messages, but I’m unable to send emails like I used to. I also can’t recover or view any of my previous emails.

It seems like something may have reset or become corrupted, and I’m not sure how to restore my old messages or fix the sending issue.

Could you please help me get Thunderbird working properly again and recover my old emails if possible?

Thank you for your support.

Someone hacked my thunderbird account and I can't get to it. How can I find the password that is now associate with it? I was told the provider has to do that, but Spectrum can't do it. I tried independent software, but the password it recovered is an old one and it doesn't work. It doesn't show up in the list of saved passwords.

I have changed Thunderbird E-mail account from IMAP to POP3. My question is, How do I get all my E-mail folders from the IMAP into the new POP3 account. Nothing followed the changed accounts formats.

Prelude: Monitor specs matter: Samsung Odyssey G93SC [Monitor] 1194.7 × 365 × 180.8 mm (approx. 47 × 14.4 × 7.1 inches) on a NVIDIA GeForce RTX 5080 [Display adapter] Display is 5120 x 1440 (recommended) Scale = 100% ISSUE: Fonts in Thunderbird size varies from readable to very hard to read.

Screencap below with filename [font-size-R4--181158.jpg] on your device at 100%, I hope, will show what I see.

Some Fonts in different Thunderbird 'panes' are unreadable without zooming in. The {body} of a reply is very small (see font-size-body--Rev3-07-19-2026_01.jpg below) The image will show the cursor at top left of Body.

I did search here but nothing of this nature it. So here is my question:

QUESTION: Is there a way to edit a config file or the likes to set fonts to be responsive (like a web site is same in any size screen and compensates for size?

Thanks for the read,
