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.

Outlook for Mac will no longer support local folders sometime in October 2026. I need to move my local folders to Thunderbird. I don't see any options for doing this.

I use a Thunderbird add-on named "Full Address column" on my Windows 11 system. (TBird version 152.0.1, moving soon to 156) It adds a field with the heading: Sender (@) I would like to filter incoming email based on that field. I see that I can edit a filter to customize a Message Header. Should I use Sender (@) or just Sender Or something else ? The use case is rare enough that I thought I'd ask here before experimenting.

I use Thunderbird to access my Gmail accounts. Gmail is confirgured for IMAP and I am able to access all of my E-mail accounts ... so that is good.

However, I do have one issue: When I delete an E-mail in Thunderbird, it moves to the TRASH folder and I empty that daily. However, when I go to Gmail, I can see that they are STILL in "All Mail". If I access All Mail in Thunderbird and delete messages, they reappear.

The only way I am able to get rid of them for good is to access them in Gmail. If I don;t, the All MAil folders grow like crazy and messages thgat I deleted are still there .. some were several years old.

Question: Is there a way to set up Thunderbird so that when an E-mail is deleted in Thunderbird, that it takes it out of "All Mail"?

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?

Something seems to have changed recently with the PDF rendering in Thunderbird. I received an email with a PDF file attached. When I view it on the screen it looks fine, but when printing it out from within Thunderbird part of the top of the first page missing; it looks like part of the image is behind a white rectangle.

When I save the file and print it using Acrobat Reader it renders fine.

I don't know what to make of this behavior, but it does seem to be new and there is a difference between how the file is printed from Thunderbird as opposed to printing using Adobe Reader.

Thunderbird 152.0.1 on Windows 11 PC.

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.

Hi, I have two accounts in my Thunderbird. They are Gmail (regular gmail account) and CFCC (an institutional account). The CFCC shows up in my Unified Folder list but the Gmail does not. Is that normal? The main Inbox is showing all incoming emails from both accounts so no performance issues, just wondering how to get rid of the CFCC (if that's possible) to eliminate clutter. Thank you. GES

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?

Thunderbird 152.0.1 Windows 11 Pro 10.0.26200 Build 26200

When I create a new e-mail or reply to one that I have received I am able to type in all fields, but there is no "Send" button to the left of the "From", "To", and "Subject" fields.

I can work around this by clicking "File...Send Now", but that is very inconvenient when I am sending many e-mails.

Please see attached image of the problem.

I have tried looking on Google for ideas but have not found anything on this or how to fix. Hope someone can please help would be amazing!

Google -

400. That's an error

The server cannot process the request because it is malformed. It should be retied. That's all we know.

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?

When I compose an email, often a pop-up interrupts me to say "Your draft message was not copied to your drafts folder (Drafts) due to network or file access errors. You can retry or save the draft locally to Local Folders/Drafts-[my email address]."

It then gives an option to retry (which always fails), save or don't save. It's annoying because it pops up repeatedly when I am writing, and concerning if my messages are not being automatically saved.

Does anyone know why this is happening or what I can do about it? Thank you!

Suddenly thunderbird will not accept emails from Yahoo. It use to. The email shows up with a line through it like it has been deleted and the message is blank. How do I fix it? Someone suggested looking at options to see if it's blocked but I cant find the option button

I have been using Thunderbird for years and am on version 152.0.1

I also regularly use the Mail Merge add-on and this has worked great. However, just come to use it and it has put 80 messages into my Outbox but I cannot get them to send!

I hit the "Send Unsent Messages" and nothing happens.

Very frustrating and would be very happy if someone can help identify the problem!

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.
