In AM of 05/23/25 my Thunderbird mail downloaded to my desktop just fine. By afternoon of same day I get an error message (see attached) saying that it is unable to write to my mailbox. Error has continued for almost 24 hours now (thru 05/24/25 AM). I can get the email account on my phone through another program, but I like to save my important mail to my desktop storage. Please advise. (I did nothing to change my Thunderbird configuration on 05/23/25 that would have generated this message.)

Hi, Can't get rid of the funtion "threads" in Thunderbird. What I want is to ignore any connections between original mail and answers to it. I would like just to have every new mail adressed to me as new unread mail. Not deleted, not visible or marked as "read". The funtion "ignore threads" don't seams to give me that option. Except for that, Thunderbird is great. Better that Outlook since it is able to sync it's caledar with google.

I am moving from Outlook, and have a large amount on Notes. I noted that in the Import options, there is no separate option for Notes. The Notes do come over as a folder within the account. Are there any plans to break out this folder to access it on a separate tab?

In certain instances, I can no longer copy/cut from Cardbook notes. This happened in last few months. I just have time now to post the problem. I know since then Thunderbird had updates and so had windows. I am on Thunderbird 128.5.2esr and Windows 11 and firefox 133.0.3 I used to be able to select a word or many words and then right click. Then copy or paste would show up as option in a list. Now no list shows up. But control c and control v sometimes works. If I control c and control v within the note that works. I can copy from something like Word and control c and paste using control v and vice versa. But if try control c in notes and then control v in website that does not work. And that is what I use most.

Hello, there are several emails in my subaccounts that are no gone and I cannot find them anywhere. As there are a lot of confirming emails about holiday bookings I would be glad to get them back. All of my emails, that I put in presonal subaccounts before July 11th are no longer available. Thank you for answering. Yours Ulrike

Four days ago the Att server started to refuse my password (I assume that was it). After four changes of password, including in Thunderbird, the password keeps being refused. Have exhausted several att agents who can't figure out why it doesn't work. One thought the server settings were correct.

I had to delete and add back several accounts due to a change in servers (cox.net to yahoo.com). Prior to this I just had the All Folders, Local Folders and below. Now I have the Unified Folders and below, which are essentially a duplicate of the folders in the old All Folders. (See attached image) Not only is it making things confusing but I'm storing duplicate emails and it seems to be affecting performance, Thunderbird now randomly quits and restarts. So, how do I delete either the All Folders or the Unified Folders and move the few sub folders that are unduplicated into the remaining group?

I have cox comm. for internet and emails, they just changed their server to yahoo.com. Now I cannot sign into thunderbird to send or receive emails.

I find that when I click on links to take me to website through my email in Thunderbird that I will get an error message that reads "we could not verify the certificate, reason=wronghost"

But, if I copy link and copy into browser it works fine. There is a break in the Thunderbird email to the browser. This does not happen with all links but there are about three or four that I get regularly where it fails.

I have talked to a tech guy and we have tried different things and it always comes back to a break in Thunderbird email.

How do I fix this problem?

Thank you, Monica

I use Thunderboard on a PC and googlemail on an iPad. On TB, there are 2 tabs - Sent and Sent Mail. Their contents differ but should be integrated under one name but messages sent from the iPad land in Sent Mail, not Sent.

I thought this TB and Gmail could be synchronised? How??

Trying to add an Gmail account on Thunderbird. My email address and password are correct. What to do? Using Surface Pro 8, Windows 11.

ear Jasmine Tietz: We have completed our investigation and have sent you an email containing a link to a secure portal to electronically download the requested email content available in the Gmail account, INTOTHEFUTURES0957@GMAIL.COM. In order to open the email content (the file that ends in “.mbox”), use any program capable of reading .mbox format files. One such program is Mozilla Thunderbird. To use Thunderbird, please follow the instructions listed below: 1. Visit Mozilla.org and download the program Thunderbird 2. Follow the instructions and install Thunderbird on your computer. Close Thunderbird after you have completed installation. 3. Open the following path/folder on your computer: 4. On Windows XP/2000, the path is C:\Documents and Settings\[User Name]\Application Data\ Thunderbird\Profiles\xxxxxxxx.default\ 5. On Windows 95/98/Me, the path is usually C:\WINDOWS\Application Data\Thunderbird\Profiles\ xxxxxxxx.default\ 6. On Windows 7, the path is C:\Users\[user name]\AppData\Roaming\Thunderbird\Profiles\ xxxxxxxx.default\ 7. On Mac OS X, the path is /Users/[User Name]/Library/Thunderbird/Profiles/xxxxxxxxx.default 8. Look for the “Mail” folder and then the folder named “Local Folders.” 9. Copy and paste the “.mbox” file into “Local Folders.” 10. Open Thunderbird. When you open Thunderbird you'll see the mbox file under “Local Folders.” Google cannot provide further technical support.
