I am having isue on one installation with searching for emails, for example, by date and to find emails in the subfolders under INBOX. If I enter to search for a date after, say, July 1, 2025, it will only return those in the INBOX even though there are emails in subfolders after this date. Search subfolders is ticked off.

I have deleted all *.msb index files and reinstalled TB but same result.

When I try to install TB, I use POP. i then get a message that the incoming server already exists and can't go any further. If I use IMAP I get a page saying Edge: Too many requests. Also a page pop ups that says enter credentials for my email address at pop.mail.yahoo.com and I still can't install TB. What is the problem? I am using Windows 11.

Thunderbird just updated to 144.0.1 (64-bit), and now I see a blank area where message list used to be. This true for all accounts and all folders.

I used to see this issue temporarily after compacting folders, but usually (but not always) went away and messages showed up. Sometimes I had to close and restart TB. Now even that wont bring up the lists. I'm dead in the water. And, yes, I did reboot my computer as well. Screenshot of this state attached.

Thanks for any help--it's urgent. Bert

I have an account on Ubuntu that has several mailboxes. I need to shift (migrate) this to a new computer with Debian 13. So far I have tried to follow the idea of copying the hidden thunderbird folder. When I start Thunderbird it has a "Setup your existing email address" page.

This is not easy.

I have successfully added numerous Zoho email addresses for our business into Thunderbird so I can easily toggle back and forth between inboxes, etc., but I have one Zoho email address that I just can't get to add. I created a new App-Specific Password for it in Zoho in case that was the problem, but the new one isn't solving the issue, either. I've attached an image of the screen and the message I'm getting- please let me know where else I can check for whatever might be preventing this add.

I have read what is posted on adding a folder in Thunderbird.

The problem I am experiencing is that when I select the main account and add a folder it keeps placing the folder as a sub folder of the in box not a folder or sub-folder of itself.

I am perplexed.

Thank you for your help!

TB frequently freezes when writing a reply. There are no reports in crash reports. It shows this image, and says reporting to Microsoft when I click close. Version 140.4.0esr (64-bit)

How can I fix the problem?

I was out of town for a week, away from my desktop. While traveling I was looking at my email on my Android phone, and all seemed OK. When I returned to my office this morning, my one week's worth of email did not download into Thunderbird. I noticed that there was an update to the program while I was gone. Not sure how to recapture my week of lost email?

A second inbox has appeared in my Thunderbird email (desktop computer) called "inbox_conf(1)". It seems to replicate most of my regular inbox. What is this and how can I delete it if safe to do so?

Yes..I've read the solution for this. Create seperate SMPT accounts with their own unique user name connected to the account in question and make sure they have the right smpt user name etc (tools>account settings>outgoing server (SMPT)> EDIT.

I haver a list of all my hotmail (and yahoo) accounts in there with the appropriate SMPT settings and user names unique to each account.

But when sending an email, it STILL errors-out with something like 'user1@hotmail.com not allowed to send mail as username2@hotmail.co.uk'.

I don't know where to go with this - thunderbird appears to insist on mixing up the identities despite me telling it otherwise.

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Right after typing my email address and pressing "Continue", Thunderbird crashes. I wanted to give it a try after many years of not using it, but then it crashes right at the start.

Here's the crash report:

I recently transferred my Thunderbird email to a new Windows 11 laptop. Everything is ok, except the font size in received emails can best be described as very tiny. I've tried everything to increase the font size, but nothing helps. My screen has a resolution of 2880x 1880 Any help would be much appreciated. Thanks.

Hello,

I manage several emails through Thunderbird, the default account is my own, this is the one I am having trouble with.

1) I can send and receive emails. (this is an imap server) 2) When I added the account to Thunderbird in account settings it created the following folders/icons: Inbox Drafts Sent Mail All Mail Junk Spam Trash (with the traditional trash icon) Then the following folders: Drafts Important Starred Trash (Which looks like a windows folder) - If I have a trash can, why do I need a trash folder, I didn't create it.

I cannot delete emails from "All Mail", every time I delete one it reappears and at this point it has well over 8,000 going back to 2022. Most of which I don't need to keep any more.

If I go to google's website and log into my account I cannot delete them either! They come right back.

It's as if Google and Thunderbird are not talking to each other.

3) I've already uninstalled Thunderbird and deleted all the files from /users/myname/appdata/roaming/ Thunderbird/Profiles, ran Ccleaner, rebooted, reinstalled Thunderbird and added my mailboxes and still have the problem..

4) I've also tried to run Thunderbird without addons to no avail.

5) My other emails do not display this kind of behavior, just the on that is set as default.

If anyone has come across this please tell me what I need to do.

Thanks very much in advance.

When I attempt to search for emails with a date (such as after Sept 30, 2025) in the INBOX plus subfolders (checked off), it only returns those in the INBOX. There are emails in subfolders dated after Sept 30, 2025.

If I search for a word without any date, it lists all emails. If I add a 2nd condition with a date as noted above, only the INBOX is displayed. Is this a bug?

Hello! An attachment with the 7z extension is sent to the email. It is very inconvenient to save attachments of this type to the computer every time. To open them using the 7-zip archiver, you need to perform several actions (select open, find the program in the program files, and select the exe file). Can you make it so that the user does not have to perform these actions every time?

maybe once per day, sometimes more or less, i get the 'login to server failed' with the option to retry. the retry always works, usually the first time, but sometimes requires another retry. this apparently started happening after an update, because it never happened before a few months ago. i figured another update would fix the issue, but nothing has changed yet. j

is there a retry setting somewhere that i'm missing?

i have pop3 account and unchecked leave on server - but greyed and checked out is a 'leave for a maximum' which i have as 1 day, there doesnt seem to be an option to uncheck this? I dont want them on the server which is why i chose pop account. yet when i open web account, the emails already downloaded using the pop account are still there even thoug they were downloaded days ago. Why is this and how do stop this? is there a 'leave copy on server' box to uncheck that I am missing? i want to use pop to remove from server and just use locally but its not doing what i thought it would, which is remove from setver. Also it keeps repeating downloading from years ago so I was hoping that when the server synced it would stop downloading the ones it has already (mulitple times) I made an imap account to try to sort emails that way but it also shows old emails still on server. Should i delet this imap account as I already have a pop account running? Very confused. Help figuring out what to do appreciated.
