Moin,

ich bin von Outlook umgestiegen auf Thunderbird, das lief soweit alles gut, dann wollte ich meine "alten" Ordner im neuen Programm anlegen habe dabei festgestellt dass Änderungen in Thunderbird ins Outlook übertragen wird, also ich ändere im neuen Ordner den Inhalt in Thunderbird ist die Änderung auch in Outlook ausgeführt, das ist sehr ärgerlich.

Ich bin mit der Bedienung von Thunderbird nicht so gut vertraut, das bedeutet wenn ich hier was ausprobiere hat das Auswirkungen auf die Daten im Outlook, in meinem Fall sind wichtige Unterlagen futsch.

Hello, Since tuesday (2025 february 25) I can no longer send e-mails from my main account, whoever is the recipient. As soon as I clic on "Send" I get the message below: "Sending of the message failed. An error occurred while sending mail. The mail server responded: : Client host rejected: Access denied. Please check the message recipient <recipient address>". I did not change anything. I have the exact same issue on an other computer with the same Linux distribution (Xubuntu 20.04, both up to date) running the same Thunderbird version (115.18.0). What is weird is that I have no trouble to send e-mails from a secondary account, on both computers. I checked using openssl that the problem is NOT related to the smtp server. Anyone experienced the same weird issue? Thanks in advance for any help. Lucie

Although messages are being sent OK, copies are not being saved to the Sent folder.

I'm sure there must be settings that would affect this, but I cannot find them!

Thanks

For the last year or so, whenever I delete a message from anywhere in my Inbox, Thunderbird then jumps to the last message, rather than staying where I was. This is infuriating when trying to clean up my inbox, necessitating scrolling back to the previous position each time. Is there any easy solution to this?

Bonjour, j'ai perdu tous mes mail des dossiers sur la gauche entre courriers entrant, corbeille, envoyer, c'est très importent pour moi conversation avec un commissaire de justice. Les dossiers sont toujours à l'écran plus une deuxième liste en double en dessous mais tous est vide. Merci de votre aide. Cordialement DD pasdag@sfr.fr

I am no tech genius and am struggling....

I have an old laptop (L1) and now have a new laptop (L2) - wanted to make my Thunderbird messages (POP account) accessible on both so installed Thunderbird on L2. The problem I then had was that if messages went to L1 or my phone they didn't come through to L2. So I went into my gmail through google on L1 and changed my POP settings, not really knowing what I was doing. I changed it to 'Enable POP for all mail (even mail that's already been downloaded)' and 'Keep Gmail's copy in the Inbox'.

This resulted in every email I'd ever had since setting up my Gmail reloading into my inbox (20K messages!) on L1. I now get new messages on both laptops however nothing is showing in any of my L1 Inbox subfolders (I had everything nicely filed...), and on top of this if I make a new subfolder the folder appears but if I moves a message from inbox to that folder the message disappears i.e., it's not visible....

I restarted Thunderbird after this and got an error message 'Couldn't load XPCOM' but I can still see all my inbox messages so seems to be starting up OK but the folder problem persists. It's maddening as I can't sort out my 20K messages into manageable folders....

I'd really like to understand - in an explanation fit for a tech dunderhead - what's going on. Both to fix it, and to stop the same thing ever happening in my Thunderbird on L2....

It'd be much appreciated if someone could help me unravel :)

I have a problems receiving and sending emails from and to externals users. However I don't have this problem with the emails receiving and sending between my coworkers (we have the same domain @spectratech.gr). We checked the SMTP settings (IMAP/POP3), SSL/TLS settings, updates and these setting seems to be ok. What could be the problem? thank you

Hi - I have a problem very similar to https://support.mozilla.org/en-US/questions/1493859?page=1 I think.

I am unlikely as technically savvy as user @iwright2 though.

I am running a MacBookPro 14.1.1, Thunderbird 129.7.1esr

Like the other user, this is no doubt due to my overstuffing of folders. I have, as a friend says, terrible computer hygiene.

I can see from the size of the empty inbox that there are many messages there. These messages all display in AllMail and outbox. These are all embarrassingly large.

I believe the problem stems from my searching on a string in one email's inbox and highlighting just these - they numbered n=60 I think, and I transferred them to an inbox on a different email account. They transferred slowly and after that, the entire first folder was empty.

This is a mac, running a lot of different gmail accounts all as IMAP.

Perhaps I need to restore some file, but I'm pretty nervous to do this. I will backup the computer first.

I'm not sure what else to tell about or investigate. Is there anyone who might be willing to help see me through trying to restore these emails to visibility. I tried someone's suggestion to change the display parameters, but that doesn't work. I must have messed things up in the transferring. I can also try repairing a disk as suggested in the other thread, though I'm not sure that's the root of the problem, I think the transfer amid way-too-big-files is.

Thanks - Huge Thanks!!! - if someone has a thought/suggestion as to where to start.

My Macbook Pro has been crashing - sometimes Firefox, sometimes Thunderbird -sometimes multiple times/day. I've saved many of the crash reports in case they might help someone know how to fix this. An Apple tech person diagnosed my memory was broken, so I just got a new logic board and reinstalled all my data from my Time Machine backup. Then a message popped up that Thunderbird was damaged and should be put in the trash. Around the same time i replied to an email from someone at Thunderbird donor who was responding to a question i had about a small donation i tried to make - i explained i was having trouble with Thunderbird. At that time, i could see the Thunderbird icon in my task bar. When talking with someone from Apple support this evening who was helping me answer a couple of questions, including about a new "mail" icon that showed up in my task bar, I mentioned that i'd like to learn how to back up or archive my emails in Thunderbird. That's when i saw that the Thunderbird icon - had disappeared. The Apple support person and i searched all over my computer for the Thunderbird app, but couldn't find it. I'm really nervous. I have over 300,000 emails I've been wanting to learn how to archive - or something. I don't want to delete most of them. I hope someone can help me find everything. Thank you.

I just changed the incoming and outgoing servers on Thunderbird. Both are the same server name. I can send emails but when I check email, the incoming server times out. I added the account that I check with Thunderbird to Outlook and it both receives and sends emails.

so i made my Microsoft account [email]@GMAIL.com insted of [email]@outlook.com so then how can i use my microsoft account WHEN thunderbird knows @gmail= gmail.com and knows @outlook = outlook.com PLS HELP PS: im useing family link so im useing a bypass from microsoft. ;)

Trying to create a Group of ten people. Went to New Message, File, New, Connect where I filled out the Group name and emails of people in in it and then clicked add to Personal Address Book. Then there wasn't any other choice but to x it out but when I went to use the Group in an email it wasn't there.

if i move a message from my Thunderbird inbox on my PC to a folder in the local folders, the message moves correctly on the PC, but remains in the inbox on my iPhone.

If I delete a message from my Thunderbird inbox on my PC, it is deleted correctly on the PC and on my iPhone.

Any ideas why moving a message to a local folder is acting up suddenly!

I need to move around 9,000 emails from a business Google workspace email to a personal Gmail account. I successfully exported all 9,000 emails to a Mbox file. I added the new Gmail account I want to move the emails to and the exported file to Thunderbird and it shows over 20,000 emails in Thunderbox (even though there should only be around 9,000). I have tried moving the email file to the new email account within Thunderbird twice now. Both times it shows like it is moving the 20,000 emails but when it finishes it only moves around 1,200 emails. How do I get it to import all 9,000 of the emails that are in the exported file?

Background - my old (selfhosted IMAP) server died, I was able to recover the Maildir but for whatever reasons both dovecot and courier ignore the "message read" metadata embedded in the filenames so the local copy in Thunderbird is suddenly the most authoritative.

But every time I try to bulk copy from the old account to local folders or to my new server it fails because it tries to contact the dead server.

Looking for ways to attack this problem
