Bonjour, J'ai effacé par erreur un dossier et ses sous-dossiers directement dans ma messagerie Orange. J'ai ensuite installé Thunderbird qui voit ces dossiers dans la poubelle mais ils restent désespérément vides des mails qu'ils contenaient. Est-il possible de les récupérer malgré tout svp ?

Thunderbird. When I open an incoming email (double click) it goes immediately to single window in compose mode, with my name as sender instead actual senders email address. There is message at bottom “A unique identity matching the From address was not found. The message will be sent using the current field and settings from identity (my name)”

This happened just today (16 jan 2025). Previous email already received and read without any issue, also come up in the compose message mode.

I have win 10 installed on desktop. Thank you Steph

Hi all, When I reply to an email after I click send, the email is somehow not sent to where it should be going but comes back to my inbox. If I select that incoming email, go to the Message menu, select Edit as a new message, and just send it straight away, it gets sent to where it should be and is put into the sent box as well. Is there something I've done wrong in the background, or is it a bug. Thanks in advance Steve

I want to sync my Thunderbird calendar on my win11 laptop with my new Samsung Z Flip 6 phone. I have a Google calendar on the phone, and I've ticked "Lightning" on it, but I'm not getting my entries transferred from my laptop.

Can anyone help, please?

The 'Sent' file in my 'Mail' folder exceeds 3 GB (3,224,360,399 bytes) and is not being read in the TB Mail window. How can I reduce the size of this file AND save messages???

'Sent' message folder IS searchable!!!

Hi,

  Thunderbird on Ubuntu for many years. Started from Ubuntu 20 or so it periodically stops receiving mails from pop yahoo account. Nothing described in community threads helps. It can be for month, two or three, then at some moment it starts receiving emails(nothing changed, even server not restarted, thunderbird keeps hanging not receiving emaiils) and receives for some period(can be couple of days or few weeks). after that it can stop receiving again and it hangs for long.
 This situation is for few years for now. last time it stopped receiving emails in mid of December. before this it was working fine for couple of months. 
 As nothing changes on my side I assume issue is on yahoo?

current release: Ubuntu 24.04.1 LTS 128.6.0esr (64-bit)

 When not receiving emails I can see following in error log:

op3.server2.1: NetworkTimeoutError: a Network error occurred Pop3Client.sys.mjs:380:18

   _onError resource:///modules/Pop3Client.sys.mjs:380

pop3.server2.1: SecurityError info: Pop3Client.sys.mjs:422:20

   _onError resource:///modules/Pop3Client.sys.mjs:422

One of my six different Gmail accounts that I have active in Thunderbird takes forever to catch up and load up compared to all the rest ... this has been going on for years

The update bar in the lower right will sit there at halfway through for minutes... .

Attach screenshot please look at the bottom right corner also

Thank you for Anybody's help Craig, Seattle

I am currently using Thunderbird (128.6.0esr) on a Mac with OS Sonoma (14.7.1). I have used Thunderbird for many years with a Gmail account on both Windows and Mac machines, and it has always worked well.

But a couple of days ago when I tried to open Thunderbird it went into some kind of loop. The MacOS spinning beach ball appeared and would not go away no matter what I did or how long I waited. The only way out was to Force Quit Thunderbird. Rebooting the Mac and trying again produced the same results.

I have logged into the Gmail account on the web and had no trouble accessing it. But every time (and I have made many attempts) I try to load Thunderbird the spinning beach ball appears again.

I cannot check any of the various settings that Help articles have suggested checking since Thunderbird will not load at all.

If anyone can suggest how to resolve my problem, I would greatly appreciate it.

I have been using the old Microsoft Calendar app on my laptop to manage my Google calendar which is also shared on my android phone, but the MS Calendar app no longer works after the latest Microsoft update. I decided to switch to using the calendar in Thunderbird since I already use it for email. But I get an error if I try to import a single calendar event from a .ics file.

I successfully shared my entire Google calendar read/write in Thunderbird and I can create new calendar events, so I know that it is writeable. But when I attempt to import a .ics file, I get an error saying "Import failed unexpectedly. more information may be available in the Error Console." I don't know how to view the Error Console, so I'm stuck. I can see that Thunderbird opens the .ics file and previews the contents just fine. But the last step of the import process fails.

Why won't Thunderbird import the calendar invite in a .ics file into the calendar from my Google account?

My husband's emails are arriving at his correspondent as though they have come from my email address. This means that his correspondents keep replying to me and not to him. So far I have not been able to see anything wrong with our settings. Any ideas as how to correct this, please?

Hi, I am moving from Outlook and struggling with Thunderbird email accounts I wish to setup 5 mail accounts, four of which relate to different people or departments and on that collects incoming email from mailboxes that are re-directed. I find that I can set up the outgoing smtp and the incoming smtp but I am not give any choice for sending mail. Also whatever I do the first account I set up always appears as the only account visible in the folders pane. If there is a definitive explanation of what to do to configure email in Thunderbird it would be most helpful?

Regards Greg

Hi All, When I use Thunderbird's calendar to schedule an event it always defaults to the next available time. For example if I go into the calendar and pick a Tuesday 1pm-2pm slot on Monday at 8:30 the event pops up defaulted to Tuesday 9:00-10:00. Is this a setting I can change? To get it to pop up with an event Tues. 1-2. Thanks, Lisa

Alwasy had Inbox drafts sent deleted

 subfolder1
 subfolder2

etc etc.

re-added my account after moving to MS 365 from another iMap account

now have inbox then all my folders then drafts etc.

Is there a way to revert back?

Also another query, ref subscribed, in all my years never noticed this setting before (never had ny hidden) but I used import/export tool to backup from old server to import for the new one (may also be relative to my problem above) The folders were all hidden on import.

Can you advise if subscribed just hides these folders or actually prevents syncing to the server. I can test but would like to understand the purpose of this feature?

Thanks I/A

The problem with standard email storage methods is that they don't scale well. Mbox, the default in Thunderbird, creates large files, and if you backup changed files, every backup requires recopying a multi-gigabyte file, because it has changed when even one message was added or deleted. Maildir, the alternative, puts each message in a separate file. But file systems have a lot of overhead and their own limits. When you have hundreds of thousands of messages, especially on a PC, that clutters the computer's file system, and between the file cluster size and directory overhead, it wastes a lot of space and slows down other operations. Two bad options. And let's not be too snarky about what that company from Redmond does in its awful mail system, with a giant proprietary mail database file that sometimes gets corrupted...

It is obviously a lot to ask to create a new mail file format that scales better. It would not be standard and could break some things anyway, though in the long run it might be a good idea. But I have an idea that might work for Thunderbird. As it stands now, it is possible to create archive files by month or year. Then new mail doesn't require those to be re-copied. WHAT IF a "virtual mailbox" could be created that, instead of consisting of one Mbox file or one maildir directory, consisted of a set of Mbox files treated by the UI as one? Quick Filter would filter them all as one, unlike with archives, and you could scroll through them all and sort them and see threads, but they'd be stored as monthly or annual (or whatever) files, the way archives are. Sending and receiving would be unchanged, using the current folders, but periodically the folder could have the oldest ones moved out and still made part of a virtual folder.

There are some modest virtual folder capabilities now, but I don't see how to do this. Does it seem like a possibility with what's there, or a modest enhancement, or is that the kind of thing that would be a huge effort?

Hello, Using a MacBook M1, MacOS: Sequoia 15.2.

New Thunderbird version (Version 128.6.0esr 64 bit) automatically downloaded this sunday 12 th. In the write email screen I still can input "To" and "Subject", but I cannot write any text ! Send button now inactive About Thunderbird (after clicking "Thunderbird top left) now inactive "Settings" now inactive Contact list on left side is empty (as shown in capture 1)

AlsoThunderbird now opens up in this window (capture 2), whereas before it would open (correctly) with the "in messages" Thanks for your help ! Dikran

I deleted all of the .msf files from my profile using a tool called "thunderfix." To the best of my knowledge, all that it does is remove the msf files from the profile folder. It's always worked well and cleaned up a slow opening inbox for many years.

However, after running thunderfix yesterday and restarting Thunderbird (Win 11, version 128.6.0esr (64-bit)), I could hear the incoming message chime, but the messages never appeared.

The screen was blank on first open, with no messages appearing, existing or new incoming ones, but the existing ones appeared after I moved to another folder and returned to the inbox. The new messages never appeared. I know they were sent and received as I keep a backup of all of my incoming emails on a separate gmail account.

Once the inbox came back with the existing messages, new incoming messages appeared as they usually do.

Does anyone know what might have happened and if the 10-15 missing messages in Thunderbird can be recovered without resorting to the the gmail backup?

Where did they go after I heard the incoming chime?

Also, is Thunderfix no longer a reliable tool?

Hi, I'm wondering if the following is a bug.

I'm using thunderbird 128.6.0esr. When I want to use "Edit as New Message" or inline Forward on message signed with S/MIME, the message body becomes empty. It does not matter if it was signed by me or anybody else. I tried reinstalling thunderbird.

Hi. I´m having trouble with my email account. It works fine on my desktop, but when I use it on my laptop it repeatedly starts by fetching 19139 mails to my mailbox, and to be frank I do not have the time to wait for the completion of that task. I have tried to delete and re-install Thunderbird several times, but that doesn´t help. Any ideas or comments??
