It seems from reading on forums and googling that there is a "return receipt" function in Thunderbird. My problem is I can't find it anywhere in my software. I've searched in every category and can't even find an "Options" on the menu. I remember when Thunderbird did have a "return receipt" that was very easy to find. Now it seems that it has disappeared altogether. What gives?

When I move or copy an email from one Exchange account to another the content and attachments are wiped out. The header (date/subject/from/to etc) is all intact. It happens to most but not all emails. This started on 27-Sep-24.

I'm using TB release 128.3.0esr (64-bit) on Windows 10

I've tested the same action within Microsoft Outlook and it doesn't happen. Therefore it appears to be a problem with Thunderbird or OWL. I am in touch with OWL at the moment who suggest removing and reinstating the accounts. I have done this but it make no difference... the same thing happens.

I can move emails to an IMAP account and this is fine... so it's only happening between Exchange accounts.

One of my inbox and sent folders (for one particular email address) lost most of its contents. I was able to recover the contents of the inbox folder by using "repair" under "properties" of the folder, but it didn't work for the sent folder. I've tried importing and restoring backups to no avail. I noticed a big change in the size of the folder in a series of Acronis backup files, but can't seem to bring the contents of that backup into Thunderbird. I've tried creating zip files and importing, but nothing works.

Hello, I've been using thunderbird since 2013, and have never had as many issues as I have this year. I reinstalled Thunderbird (uninstalled with revo uninstaller so nothing stayed), and then installed the latest version fresh. This seemed to smooth out most of my issues, but I haven't been able to solve this one..

I use Thunderbird because I have multiple email accounts to monitor and like them all in one place. The latest problem that I am having is that my "sent" email is showing up as giberish (sometimes.. Not every email, and not always on the same account).

My system is Windows 11 Home 64-bit

I will attach a screen shot of: 1. My current version of Tbird 2. The email that displays in Tbird 3. The email that displays in Gmail

Thank you in advance! -Eric

There are about 16 attachments that appear following various folders when I start Thunderbird. I can delete each each individual folder and they appear in Trash. I delete them from trash. As long as I don't close thunderbird the attachments stay gone. When I close and restart Thunderbird, they reappear. Ir I don't delete them before closing, they reappear when I start Thunderbird again. In this case about 1/2 the folders can't be deleted. After several start, close, and delete sequences I'm back to the initial condition. The attached images show Startup with all the extra folders, then the cleanup process, and finally the extra folders in trash. Once in trash they can be deleted.

I've been happily using Tbird for many years until in January I got the message "Cannot open inbox as it is in use for another operation" and later "Thunderbird has crashed". I have been using webmail since, not at all satisfactorily. I've made many attempts to get help but always go round in circles - today's framework seems more promising. Can you help please? Richard

Starting on 10/01/2024 Thunderbird no longer allows me to send or receive email.

When I try to read messages using Thunderbird, I get the following: Sending of password for user XX@msn.com did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password.

When I try to send messages using Thunderbird, I get the following: Enter your password for XX on smtp.office365.com:

I have tried redoing the password and it does not help.

This is on a WIN/10 system. I updated to the latest version of Thunderbird and it did not help.

I checked out Thunderbird on my WIN/XP and get the same results as with WIN/10.

When I use Firefox and login to https://outlook.live.com/mail/0/, I can send and receive email as before. The same is also true with my Mobile Phone.

When I send emails, some go to my trash folder and not my sent folder.

I have no way to tell if the email was actually sent out.

I have tried resetting we are updated I cant find anything on the internet or youtube

this is now a recurring event and need to get this figured out as this is affecting my business.

I just run into a weird bug in version 102.9.1 (yes I still use this for a reason).

I have some Alias email addresses, that is, on my Linux mail server they get re-directed to my main email address. However, when I *reply* to such an email address, Thunderbird swaps the From and To (and Reply-to) addresses, and send the email back to myself, from the From address the person who send the email to me in the first place. This is really bad.

So it seems when the email address does not exist in Thunderbird itself (as it is a redirected Alias) Thunderbird gets completely confused and mixes everything up?

In this case, my actual email address is bk@bart.gen.nz The alias is bart2@bart.gen.nz

When I click 'reply' it sets to TO address to bart2@bart.gen.nz, instead of the Reply-To "info@sartrack.nz", and the FROM address to "info@sartrack.nz". How is that possible? See original incoming email below.

An identical email but directed to my actual email addres, and the Reply works normally.

Thunderbird sometimes deletes more than one email when I try to delete just one. The system will delete the next one or two below it which is very frustrating. Is there a way to fix this?

Someone has hacked into my addressbook. Incoming emails have been blocked and I need to unblock. If I now send and email I do tend to get a reply but the hacker still seems to have control of my emails

I'm on version 128.2.2esr on MacOS (M1 Macbook Air) and an email that I've sent today appers wrong in the "sent" folder as show in the attached screenshot.

The email is shown in the sent folder properly in other clients (Apple Mail on iOS/iPhone) and webmail from email.cz which is my email provider. One of the recipients of the email confirmed, that he's received the mail correctly.

Thank you!

Everytime I try to open thunderbird to view my emails, it requests my password.... then asks again and again reoccuring and still does not work I have uninstalled the program and reinstalled it yet it has just done the very same thing

I used Linux Mint 21 and exported data to import into Mint22. All the files have been imported but nothing shows up on Thunderbird. How can I install them? Some are very important to me. A couple of screenshots to try and explain better. Any replies to brian/at/casadelpi.casa. Thanks in advance

I have several POP Mail Server accounts from which I download emails to Thunderbird, including two accounts with Gmail and two with Zoho. I have them configured the same way on both a desktop and a laptop computer.

Up until Sept. 26 all were working fine. After that date, however, I've been unable to download mail from Zoho on either computer, even though I still can download from Gmail. Strangely, I get an error message when I try to download using the desktop computer, but don't get one with the laptop. In neither case, though, will the Zoho email download. The error message, titled "Error with account Zoho_cof", says:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I have plenty of disk space on both computers and have not changed write privileges.

Since the problem is restricted to Zoho and occurred simultaneously on both computers, I thought the problem lay with Zoho. They, however, claim that the problem lies with Thunderbird.

I've attached screenshots of the configuration page for one Zoho account (which stopped working) and for comparison one Gmail account (which continues to work).

I've run Thunderbird in Troubleshoot mode and still get the problem. Can anyone offer a suggestion as to what to do? Thanks!

I have a suggestion or rather a complaint about control V text into an email message. The spacing between lines is too compressed when a picture is also sent. See image below...
