Since the latest update to thunderbird 128.5.0esr, I have not been able to download mail, just get the message "Mail server connection timed out" I have multiple email accounts on thunderbird none of them can connect. This looks like an issue with the latest update. Thanks Kerryk

After Thunderbird just updated to Version 128.5.0esr today, now all my accounts are saying that the connection is refused. This is coming from three different email services that I have accounts on. I'm assuming it's not an issue with those servers as I can access them just fine with a different email client, and I didn't change any settings. Yesterday it worked, today it doesn't. Only thing that seems to have changed is Thunderbird got updated.

128.5.0esr (64-bit) / Windows

After a dozen or so minutes from starting, TB goes into a kind of suspended mode - it does not receive emails, and the bottom progress bar (from Activity Manager) remains unchanged (for example: it indicates 50% progress, but after clicking on it, Activity Manager does not show any ongoing activities) until TB is closed. I have 6 supported accounts + local. I have already reduced the number of supported emails lying in the mailboxes for the test, I have turned off indexing. The problem still occurs.

How can I investigate what is taking up TB so much (that it cannot receive emails) when Activity Manager does not indicate any activity?

Best Regards.

After updating to 128.4.4esr I can no longer send email - NS_ERROR_FILE_ACCESS_DENIED. I can create a new message, hit Ctl-S to save and I get a dialog box of "Status: Creating mail message..." and a progress indicator that is at 100%. I also get an error of "Unable to save your messages as a draft. Sending of the message failed".

If I attempt to send and email I get the same creating mail message and an error dialog box saying "Sending of the message failed".

In the error console I see

• Bulleted list itemSending failed; , exitCode=2152857621, originalMsgURI=imap-message://[email protected]/INBOX#67121
• NS_ERROR_FILE_ACCESS_DENIED: Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIFile.createUnique]

I looked at my ~/.thunderbird directory and the permissions are 700. I'm on Ubuntu 24.04.

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]
