I am really really distraught right now. It took me two weeks to get the time and focus to write a long reply to a company's nice email to me. Stayed up till 2am to write it. Deliberately wanted to re-read it in the morning before sending. Gone. Nowhere to be found. I pressed "Save to draft" before closing my laptop. But not saved. This account actually has a "draft" folder, unlike most of my other accounts in Thunderbird, which I also cannot figure out and no one has helped me with.

I have several email accounts of all types (IMAP, POP, etc.) managed by a single Thunderbird instance (v140.3.1esr 64-bit) running on Windows 11 (latest update).

A few weeks ago, I noticed that the 'Trash' folder on one of my IMAP accounts lost the 'Empty Trash' context menu item. Email I deleted still went to the 'Trash' folder, but I needed to delete them manually. 'Trash' folders on other accounts continued to work as expected.

This afternoon, I noticed that the deleted mails were no longer going to the 'Trash' folder. Looking this up online, I found the following old topic from 2023: https://support.mozilla.org/en-US/questions/1420657

However, the link cited within that post (https://support.mozilla.org/en-US/questions/1156586) no longer seems to exist and the details cited there no longer seems to be applicable as the interface and other details provided are no longer representative of the product today.

The elements of the post that seem applicable is a potential corruption of the 'Smart Mailboxes'. If I look at <ProfilePath>/Mail/smart mailboxes, I have several files associated with folders that may or may not be associated with the 'Trash' folder of the email account suffering from this problem. Given the date stamps, I'm not sure what they represent or even if they are involved in the currently running product.

Do note that I have been using this client for more going on 20 years.

Can you please provide updated troubleshooting steps and help me understand how I can map the folders under 'Mail' to the appropriate accounts to be sure I am not disturbing account email that is functioning properly.

Thanks in advance for the help,

AJ

When trying to add my outlook.com email account to Thunderbird 143.0.1, using the instructions at https://support.mozilla.org/en-US/kb/thunderbird-and-exchange, I get an "Exchange auth error." I'm able to add the account manually using imap, but I want to use Exchange so I can access my outlook.com calendar and contact when TB is updated to include them.

I have been trying to filter out and delete emails with certain URLs in the HTML section of the body of the message.

I can get the Body filter to activate and delete the email if I send the specified URL within a simple text message. So the Body filter can activate on sequences in the text part of a multimode or simple text email.

It doesn't, however, seem to activate for the thing I truly need, which is to see a URL (or other sequence) in the HTML part of a multimode. It appears to ignore the HTML section.

Would it be possible to either:

1) allow the current Body filter to scan all parts of a multimode message? OR

2) create a new filter, perhaps named Rawbody, or Raw, etc., which doesn't break down and separate the parts of a multimode first, but simply does a raw scan of the entire body: text, HTML, and all?

Thank you.

Hello!

I recent upgraded my work computer to a new Mac mini. I reinstalled thunderbird but I am having issues with the drag and drop feature for email attachments.

Normally when I receive an attachment I am able to drag and drop the attachment to the folders on my desktop. This feature has not been working. I have tried doing this in troubleshoot mode and have had the same issue. I’ve also deleted thunderbird and reinstalled it with no luck.

I am on Thunderbird version 143.0.1 (64 bit) My MacOS version is Tahoe 26.0.1

Any suggestions on how to fix this issue would be amazing. Thank you!

Thunderbird Email - I am not receiving emails from my energy supplier (E.ON Next) - they say they bouncing. This started around Jan 25. I have spoken to them many time but no joy. E.ON receive emails I have sent to them and I am able to receive emails from just about anyone else eg shop, banks, contacts, etc etc . Can you help me fix this/explain why it is happening? Many thanks Jane

Hi, when i wrote an email, and i wont to attach a file from PC, when i select the file with extension .pdf, the file did not shown in preview pane. I try everything i think, but it wont work.

I'm trying to add accounts through the hosting provider Strato, but as soon as I add a new email, it asks for my name and email address, and I can only click "Next." Then it searches and searches, and I can't cancel without forcibly closing Thunderbird. How can I change this? Why can't I do it manually? Antivirus and firewall are already disabled... it doesn't help.

Good morning.

Problem 1. I've been using Thunderbird for a very long time. Everything has always been fine. But recently, I've been having trouble sending email from one of my accounts. When I try to send a message, a message appears: enter the password for the user... Entering the password doesn't help, and another message appears asking me to contact the network administrator. I contacted them, but they didn't find the cause of the problem, but they suggested changing the password, which I did, and reinstalling Thunderbird, which I didn't do for fear of losing all my email. Changing the password helped for maybe two weeks, and then the problem started all over again. The problem only affects one email address and only on one computer. Sending messages from that address on Android works without any problems.

Problem 2. I installed Thunderbird on my Android phone and encountered a problem when adding two accounts: the first installed without a problem, but I can't install the second one because every time I try, I get a message that the incoming mail server check failed - unknown error 42.

Problem 3. I'm trying to install the program on my second phone - it downloads 99% from the Google Play Store and that's it.

Is there any way to solve these problems, or should I change my email program? Best regards, Andrzej Witkowski

Thunderbird being used as IMAP client for Gmail - with no issues, until recently when an existing email recipient, who sits behind the Barracuda Networks system, fails to receive mail from Thunderbird's recent versions because it is rejected and blocked by Barracuda. I have tried using plain text formats and checked that SMTP server accounts are correct all to no avail, a 550 blocked is the result. The Thunderbird ver is 143 64 bit - However mail from an earlier 32 bit version 115.5 was successfully delivered, later 32 bit ver 140 failed to deliver through the Barracuda system.

Email from Google's own Web client gets delivered and mail from the Android mobile phone app likewise arrives. A simpler IMAP client (MailSpring) manages to get mail thru Barracuda so what has Thunderbird done to appear a threat to Barracuda ? BTW Mailspring is sort of 'Ok' - but it just isn't Thunderbird - it was installed only as a test vehicle !

A disaster happened, but first, let me say that I had to create a new Thunderbird Profile because Thunderbird was acting really strange and also making my e-mails fail DKIM for some reason. After creating the new profile, things were working better, but still some problems. It's been several days. Twice it marked my own e-mails as Junk, and both times I marked them as Not Junk, but that didn't seem to "take".

An e-mail in my Drafts folder is my "in case of death" e-mail. I was editing it to change the To addresses, then told it to save as Draft. That immediate Draft went straight to the Junk folder. WTF? So I go to the Junk folder, select it, right click, and "Mark as Not Junk".

Instead of going to the Drafts folder, Thunderbird sent it. Not only that, the old Draft of the e-mail was sent also!

I'm royally pissed off! How could Thunderbird do something so stupid? First classify my own saved Draft as Junk after my having marked my own e-mails twice before as Not Junk, then send it when I said it was not Junk? This is stupid.

Needless to say, I had to hurriedly sent a retraction e-mail, then made phone calls.

Something is really wrong with Thunderbird Junk processing. After creating the new profile, I've seen junk e-mails sit in my Inbox for 15 minutes before suddenly Thunderbird decides that they are junk.

Thunderbird WAS a good program, but after having to start over with a new Profile, setting up my e-mail addresses again, install add-ins, go through all the settings again, import my e-mails, addresses, and calendars, then have things still going wrong, I'm wondering why I'm still using Thunderbird.

Is there an extension or add-on that can search like the old Eudora does? The default search does not seem to search thru headers or all email messages This is important for us when we need to find the Senders IP numbers so we can ban the spam emails

I've installed Thunderbird on new computer, and moved over from the old computer emails and Address Books (including customized ones). But when I start a new message, I can't get any e-addresses to appear in the To box.

What do I need to do to access Addresses?

Hello- I have the drafts being saved locally to a draft account but in the last week, drafts are disappearing rather than being saved. I did change severs over the summer and have had a slew of issues since then, but this is a new issue as of this week. I have multiple email accounts and this is happening on all of them. I am on a mac 140.3.1esr (aarch64). Thanks for any help- this is a debilitating issue.

Hi, Thunderbird : Under Windows 10 and Ubuntu, I have a vertical taskbar on the left. but once installed under Widows 11 no taskbar and no way to make it appear. Do you know a solution? Thank you

I noticed that I can't see the end of any longer email messages and realized that the Status bar is missing in the email window, too. Changing the relevant setting in the menu didn't do anything. The Status bar is visible in other tabs. When I hid the Today Pane (Events & Tasks), the status bar came back. When I displayed it, Status bar disappeared again. With longer email messages, it is impossible to view the complete message, because the message window seems to extend below the screen bottom. Hiding Windows task bar doesn't help.

Help, how can I have my status bar and read the messages without opening them in a new window, without having to hide the Today pane?

I have an MS email account which is passwordless and only uses fingerprint/passkey authentication.

How do I get TB to use this security method to gain access to my email? Currently, every time I try to add the email address/account, it asks for a password, which obviously I don't have.

Please excuse misspellings and anything that may not make sense or cause offence as the medication I take can have an adverse effect on my mind.

I'm on Windows 11, I've archived my gmails to a 3GB zip and extracted it to a local MBOX file. I want to sue Thunderbird only to be able to conveniently see these emails. I don't want any accounts, nor to connect Thunderbird to the internet - I juust want to see the gmails.

I've installed Thunderbird, and the import/export Tools NG add-on. It won't let me import to a unified folder, so I deleted the unified folder. I have no "local folders", so I can't right click on one and select import. I can't see how to make one either, and the help is of no help.

I wonder if somebody could tell me, without assuming knowledge I don't have, how to do this please.

Thanks Chris

My cat laid too close to my keyboard (i.e., by the control, shift, and windows button) and I am now unable to send messages from any of my email address in Thunderbird. I've checked the server settings and they all appear to be correct, but I keep getting the error message that connecting to the smtp failed. I'm receiving emails, but can't send them. Is there anything else that I might be missing apart from checking the server settings.
