Thunderbird Community Forum

Suddenly, bizarrely, some of my sub folders have disappeared. They are not "greyed out". They have totally disappeared. I now missing important content, that I need. I have been unable to find a solution by browsing on this forum. Can anyone help? And if they are gone for good, can anyone suggest how I can prevent this from happening again?

Somehow, I now have a duplicate email account. Changes to either one are reflected in the other account. So if I delete one, the other one will be duplicated. Also recently, each received email is duplicated.

I can live with each duplicated email but would like to get rid of the duplicated account.

Thanks, Sue

Hi there,

I have looked for hours on your site on how to get thunderbird sending emails, I have attached this to my outlook account and used all the correct IMAP/Port/Server settings that are displayed.

For some reason when I go to send an email, it says to me that "login to server smtp.office365.com with username ****myusername**** failed" THEN it says "Unable to authenticate outgoing server (SMTP). Please check the password & verify the 'Authentication Method' in account settings, Outgoing Server (SMTP)" I have done all the above multiple times, I have even tried other settings, and it STILL DOES NOT WORK.

I would greatly love some help with this as it is now becoming very tasking and frustrating. Please can someone help me out ASAP as I would love to start making use of Thunderbird.

Thanks - Max!

My version of Thunderbird is 128.5.0esr (32-bit).

I use Yahoo Mail. Yahoo prompted me last week to change my Yahoo password. After doing this I noticed I could not longer receive or send emails in Thunderbird. When I try to send a message in Thunderbird I get the following message: Login to server pop.att.yahoo.com with username [email protected] failed. I've tried going to Settings/Passwords/Saved Passwords and removing all Logins re-booting and entering my new password (the one I used with Yahoo Mail) without any luck.

Can you please help me get this corrected. Thanks much!!

I am planning to buy a new computer to replace my current one. The new computer will have Windows 11 and the current one Windows 10. I notice the current Thunderbird files are located in C:\Users\(username)\AppData\Roaming\Thunderbird. I backup these files every day. When I install Thunderbird on the new computer, do I copy my backed up files to C:\Users\(username)\AppData\Roaming\Thunderbird BEFORE starting the Thunderbird application on my new computer for the first time? Will Thunderbird be able to locate all of my email accounts as well the current local files? Is there anything that I need to do and/or change? Thanks for your help.

Hi I started my Thunderbird on my laptop today 2024-11-26. However, last emails are from 2024-11-19, i.e 7 days ago.

I don't see what's wrong. No filters, strange sorting or similar are applied. When I login to same mailadress via webmail instead, everything works. There I have many mails between 19th Nov until today 26th Nov.

Any ideas what can be wrong? /Best Regards Joakim

I'm finding threads that include the correct emails for the subject, but also additional emails that do NOT relate to the original subject. How do I pull the other "subjects" from being in the wrong thread and create their own thread. See the highlighted emails in the attached image. Each color represents a separate thread that should stand on its own.

Thanks.

Thunderbird puts a LOT of my mail into Junk/Spam boxes and I am missing some important stuff. Rather than go hunting for stuff I missed in other mailboxes, I'd rather deal with them as they come in. I've checked online and turned off everything I can find to prevent the Junk filters from working, but stuff is still showing up in Junk/Spam filters. What do I need to do to turn it ALL OFF? Thank you.

I use Thunderbird to check the 15 different email accounts that I have to respond to. On the 4th of June it just quit sending or receiving emails. I tried deleting some of my emails but it hasn't helped. Do you think I haven't deleted enough or would there be another reason for it to quit working.

When trying to paste a screenshot from my PC (Windows 11), it fails—it does nothing. I've been attempting to set 'mail.compose.attach_http_images' to true and selecting "Only HTML" in the "Compose messages in HTML format" settings, but it still doesn't work. However, the screenshot from the clipboard can be successfully pasted into the Paint app.

Do you have any ideas or suggestions for resolving this issue?

The Menu at the top of e-mail to be sent disappeared so I can's send e-mail. I was able to click "File" and then click "Send Now" for a few days but the menu bar just disappeared. [email protected]

I have several email accounts and in the left pane they are listed in the order I added them. I want to change the order so the more used accounts are on top. I try dragging and it does not do anything. I searched the web and only solution listed was to download an api, which I did, but does not work on ver. 128. How do I change the order that these email accounts appear?

Many moons ago I used Microsoft's Outlook as my email program. When I would open Outlook, it would retrieve all of my emails from my ISP's server, permanently removing the emails from the server while downloading them into Outlook.

When I installed Thunderbird recently, it was to do the same thing. My ISP had sent me several notices that my email account was close to full, so I was looking for an email program that worked the same way Outlook does, and removes my emails from my ISP's email server as it downloads them to my PC.

The first issue I'm having is that Thunderbird does not appear to do this? Or do I simply have my Thunderbird account/settings set up incorrectly?

My next issue is directly tied to the first one. Every time I open Thunderbird it starts re-downloading all of the emails that it has previously already copied into my Thunderbird Inbox, but that are still in my email account on my ISP's email server. This is probably 15 years worth of emails and equates to thousands of emails I'm saving, and every time I open Thunderbird it starts re-downloading them again. I simply want to be able to save them to my local email client (Thunderbird) and store them on my PC's hard drive.

The final issue is also tied to the first two: As soon as it starts downloading the emails again, Thunderbird (and only Thunderbird) lags heavily and almost continuously. It lags so badly that it becomes incredibly difficult to write a new email in Thunderbird, and so I end up closing the program and logging into my ISP's email server and using their client to write my emails, or conducting my email business via my phone, which takes longer and is more challenging due to continuous fat-fingering of the phones tiny little keyboard.

So, am I missing something, or do I have some settings in Thunderbird set up incorrectly? Or does Thunderbird simply not work the same way Outlook does (or at least use to)?

Thanks in advance for any help or advice anyone is willing to give.
