I am encountering a peculiar issue with the "Reply to All" functionality in Thunderbird, which I believe may be a bug or an unintended behavior within the application. I hope you can provide guidance or a solution.

Issue Description: When I attempt to "Reply to All" to an email that I previously sent (which is the last email in a conversation thread), Thunderbird automatically alters the sender's address. Specifically, instead of maintaining me as the sender, it changes the sender to the one (or the first one, if there's more) of the original recipients' addresses. As a result, the email appears as if it's being sent by the recipient back to themselves. This messes with the recipient's folders and rules, as the message has no indication it's been sent by me. This happens when I initiate the "Reply to All" action from the Sent folder on emails where I was the original sender. This only happens in one of the email accounts I'm using in Thunderbird, and it's a POP Mail Server type account.

Steps to Replicate:

Send an email to one or more recipients. Go to the Sent folder and open the email that was just sent. Click on "Reply to All." Notice that the sender's address is automatically changed to one of the recipients' (typically the first one, if there are more recipients). Expected Behavior: The sender's address should remain as my email address, not change to a recipient's address, ensuring the email is correctly identified as being sent by me to the other recipients.

Troubleshooting Steps Already Taken:

Verified that no extensions or add-ons are causing this behavior. Checked for any relevant settings within Thunderbird that could influence this behavior but found none. Updated Thunderbird to the latest version available. I would appreciate any advice, solutions, or workarounds you can offer to prevent Thunderbird from automatically changing the sender's address in this scenario. Please let me know if there are any logs or additional information I can provide to assist in resolving this issue.

When I activate a quick filter (like "Show only unread"), a count of the number of messages is added to the right end of the filter bar. This means all the buttons move to the left, so I have to move the cursor toggle it off again. This is incredibly annoying and unintuitive.

Is there a way to modify this behavior so that toggle buttons don't move when they're pressed?

Collecting mail one day, I received a Thunderbird message 'compact now'. After the compact process, some mailboxes are missing. How do I re-instate these deleted mailboxes?

I am running Thunderbird 115.10.1 on an up-to-date Windows 11 machine. I have 2 email accounts (VirginMedia and Gmai)l. When I look at the drop-down list from the top-level folders on these accounts the VirginMedia account does not offer "New Folder", but the Gmail account does. I can create new folders via the VirginMedia webmail, but not via Thunderbird. This is a problem which I have had for some months, coping with it by resorting to webmail.

Hello, All

I need major help, please.

I am getting the attached messages when trying to send an email. Thunderbird worked perfectly yesterday morning, but then would not send any emails. I get emails, but cannot send from my 2 accounts.

I am on the latest version of Thunderbird, Supernova 115.10.1

Also, I cannot find out where to change my password for the accounts, because at times I need to fill in a password. I can't find it.

Thanks in advance for any help.

Best, Leslie

I am having older Thunderbird 102.13.1 and when i input into a search field for example: 37.19.223. or "37.19.223." or "37\.19\.223\." it always stupidly and uselessly output tons of messages that contains unrelated IPs:

([76.223.177. [10.223.144.96]

highlighting number 223 as if i have searched just for this number 223

I think that it is reasonable to expect from TB to output only search results where email contains 37.19.223. without any hack, escaping or regex or whatever (if you know a workaround, please kindly share it).

Maybe newer TB works better? Anyone tried? If it works same way, can you please kindly ask developers to fix this?

I get this Error message when I try to send emails from my outlook email address in Thunderbird. My Password is correct, and has not been changed recently.

Any ideas please ?

Here's the technical details: Win 10 Home 22H2 Build 19045.4291, Mozilla TB Thunderbird Version 78.4.0 Build ID 20201019003438 Distribution ID Update Folder C:\ProgramData\Mozilla\updates\8216C80C92C4E828

This AM I was able to check / get e-mail five (5) or more times. Then clicking 'Get Mail' displays; connecting to mail.duo-county.com After 15-20 seconds connection to server mail.duo-county.com; Timed Out

I know of NO changes to any setting. When our e-mail was set up, we were told to set we were told to use Pop-3. Our ISP, who does NOT use NOR 'know' TB said we should be using IMAP, could NOT help review nor doing anything without risking ALL folders - files-data!

PLEASE help ASAP. Since we can't get - check mail I'm LOST! My spouse's e-mail is wpj@duo-county.com

Dear all, is there an option to have Thunderbird sync network calendars once upon start? I have a couple of large network calendars and repetitive syncing causes performance problems, but on the other hand, if I set sync to Manual, Thurderbird does not sync upon start and shows only the events that had been cached locally (off-line) in the past, but not any events meanwhile added to the network calendar by other clients. Thus, I either have to remember to manually sync once every calendar after each program start, or I have to activet syncing every xx minutes, which causes the programm to periodically freeze for some time (during syncing). Is there any good solution to this? Is there maybe an option in the config editor "sync upon start"? Thank you very much.

Dear all, I have a couple of calendars on the disk as network calendars (file:///...ics) with offline support, and I just realized that I cannot delete any event. These calendars are not read-only, I can see the option delete, both with right-click on the event and double-click to edit the event, but after pressing delete, the event remains on the calendar. Just pressing the delete button on the keyboard after selecting the event has the same behaviour. If I try shift the events from one calendar to the other, they do appear in the new calendar, but they do not disappear from the old. I have restarted Thunderbird, and also tried this on another computer with the same results. Both szstems are Windows 11, Th underbird 115.10.1 I would be very grateful for any suggestions

I added a CalDav calendar to Thunderbird that is hosted on a Nextcloud instance. While the calendar view looks decent, the tasks view is completely bloated with old, already completed tasks, some even from 2023. I selected "open tasks" or "current tasks" (? German translation) from the menu on the left side. It's not that all of the tasks are misclassified: When I go to completed tasks, there are hundreds of (correctly) completed tasks listed, but still.

Furthermore, the sub tasks of a main task are not grouped. Is this a known limitation or am I missing some configuration?

In general, as of now, the task view is pretty unusable for me. Anything that I can do to help debugging this?
