Really weird problem with a friends thunderbird setup.

All of a sudden my friend was unable to get here emails. It kept saying the password was incorrect. Of course she didn't know her password but it was saved in Fire fox. Found the password and verified her centurytel webmail works. So put it in Thunderbird and still give me an error. I then decided to install Thunderbird on my personal laptop and everything works fine. So I decide to do a clean install, deleted all profile folders and everything. Reinstall Thunder bird and get an "Authentication error". I tried disable all her firewalls on her computer (Windows 11) and disabling the firewalls on the router/modem itself. It still doesn't work. I think next thing I will try is my laptop that has thunderbird installed with her email account.

Any other ideas?

I already have View > Sort by > Date is selected, View > Sort by > Descending selected, and thread sorting set in settings. See screenshots. Threads sorting so newest is at the bottom, they should be at the top. General emails are sorting properly, newest at the top.

I’m looking for card body previews in the message list/card view, similar to seeing a short preview of the email body under the subject/sender. Is this feature currently available anywhere in Thunderbird?

If not, is it planned, and is there any estimated version or timeline for when it may be added?

I was wondering if there is a way to easily copy a saved search from one parent folder to another. I have searches I use to c apture emails for tax purposes. I use dates, subject lines, etc. to capture these emails and I have almost a dozen per tax year. It would be nice to copy my 2025 saved searches to my 2026 folder, and then just edit the dates as needed to capture the correct year. Thanks for any help you can provide.

PRELUDE: I have several email accounts. All accounts display properly, except one. Yes, this is similar to my question about bottom of the far left [of emails] list of emails - but this is different.

On the far left of Thunderbird is a list of all my email accounts with "Inbox" etcetera. Each email account shows it's Inbox/Sent/Deleted/ except for 1 account. The problem email account only shows it's Title and Inbox northing else. Yes, I tested it and sent emails to it, and used the problem email account to send, create a draft, and they don't show..

The image explains it.

Thanks for reading this ~r

I have used Thunderbird for years. Suddenly it asks for my email account password every time I send an email message. What is the problem? The passwords for my email accounts have always been stored in my configuration and it never asked for them. Very annoying.

Hello All, The opening email changed to a reader that works, but I'd prefer to use the "Classic Reader" by default. Searching the settings hasn't turned up anything that sounds right. Is there a behind-the-scenes file that I need to edit to resolve this issue?

Thunderbird shows email messages from the wrong account. The messages show properly in Yahoo website and on other computers using Thunderbird. Concurrent with this new issue, I now get message: Sending of the message failed. An error occurred while sending mail. The mail server responded: "Request failed: Mailbox unavailable. Please verify that your email address is correct in your account settings and try again."

I have verified the settings. Searching for help with Thunderbird, I see references to index files getting corrupt. However, I struggle with the correction procedures. When I right click on the bolded email address, "Properties" is not an option on the drop down menu. I cannot find a "Fix folders" button.

BTW, I did contribute December 17, 2025, it seems like a pretty good way to say "thank you!" Jim

When I try to forward email with attachment. I get a error message stating I dont have access for the attached file so every time I have to remove the attachment in the email and download the attachment from original email and attach to my email. Which is frustrating and time consuming process.

What I thick is there is storage path issue with my email setup.

Please assist to resolve this issue.

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

I have a newly downloaded copy of Thunderbird, and I'm signed in to Firefox. When I try to install it, I get as far as Creating Account, and the installer hangs with a spinning circle. Please help.

I logged into email today and most of my folders are missing from left side of screen. I have inbox, deleted, sent, and a couple more i created. I missing many folders I created. I have not had a problem like this and have used thunderbird for many years.

Until recently, when I clicked on a link in Thunderbird, it was opened in Thunderbird. Now the link is opened on a wide-screen external monitor. I can't find the setting that was changed to make this difference.

I was using TB like normally on windows 11 when it crashed. Now every time i try to open the app it prompts me to send in a crash report, but every time i press "restart thunderbird" a new window with crash report shows up. I have tried writing a comment, checking and unchecking all the boxes and pressing quit thunderbird. But i still get sent into the loop.
