Thunderbird Community Forum

Hallo,

ich erhalte meine e-Mails auf meinem Laptop via Thunderbird. Als ich letzte Woche nach einer einwöchigen Abwesenheit meine e-Mails checken wollte, zeigte mir das System 178 erhaltene e-Mails an. Als ich meinen Posteingang öffnete, zeigte es nur 78 an, die auch existierten. Es fehlten somit 100 e-Mails. Liegt das an Thunderbird oder muss ich meinen e-Mail-Supporter (1&1) kontaktieren? Da ich kein "Computer-Freak" bin, bin ich ziemlich hilflos und würde mich freuen, wenn ich von Euch Hilfe bekommen könnte.

Vielen Dank im Voraus für möglichen Support und hilfreiche Antworten an meine e-Mail-Adresse x@online.de.

Herzliche Grüße aus Berlin Harry Kühn

Kit Galloway,

A week ago my Thunderbird email-app mysteriously switched to a very thinned-down and sparse email information presentation.

I want to return to the classic Thunderbird display. I'm using the current Mac mini.

My email: X@earthlink.ne Phone: xxx-xxx-xxxx

I am using Thunderbird 115.18.0 and Windows 7 professional (no snarky comments please).

All has been working fine for years, but in the last few days, strange thing have been happening:

In the pane with all of my email accounts, the ">" icon to the left of the first account has been disappearing. This meant I could not look at any folders, including Inbox, Drafts, Sent etc and handmade folders. Cured by closing and opening Thunderbird.

I now have two Archive folders, one called Archive, the other Archives. Both empty, neither can be deleted.

Periodically, when the ">" is present, selecting it (to "V"), the list of folders SLOWLY appears, one folder at a time.

Periodically, the bottom of the Thunderbird window, shows a 'downloading' message, of hundreds of files. Several GB of data has been downloaded over a couple of days.

Opening the Inbox folder, the pane with subject, correspondents, date etc has changed the sort order.

Sometimes, all of the emails in this pane have had their font underlined.

Nothing on my system has intentionally changed,

Any ideas what has gone wrong, and how to put things right would be appreciated.

Thanks,

I am setting up Thunderbird on a Win10 machine, and am having a lot of trouble adding accounts that I did not have on the two Win11 machines I have set the same accounts up on.

When adding my 2 GMail accounts, after clicking "Allow" on the OAuth popup the button would go grey the window would stay open and not close, and the account would not be added.

Changing the general.useragent.compatMode.firefox option to TRUE allowed me to progress and finally add those accounts.

I am now having the same trouble with my @hotmail.com account. When I add the account, the dark blue OAuth window pops up, but is completely empty, and there is nothing more I can do.

Things I have tried

• Reverting the above config change
• Checking that cookies and JavaScript are enabled
• Checking there is no saved password
• Used both the Account Hub and the default dialog, with the same effect.

Thanks in advance!

my server is charter.net never had a problem with thunderbird and then several months ago i stopped being able to reply to emails

Is the feature supposed to behave this way? I find this rather tedious. Am I missing something here?

Current behavior:

My installation does not seem to automatically execute spam filtering for unified folders or saved searches. As soon as I manually select one of the included folders within - e.g. an individual mail acccount's inbox - the algorithm triggers and everything works as expected, but only for the one folder I clicked. This leaves me with having to click through all my mail accounts manually to make use of the adaptive junk mail controls function.

Expected behavior:

Selecting a unified folder triggers junk mail controls for all the included folders and moves messages to the respective junk folders automatically.

There are emails after the blanks and I am not sure if any are missing. Also some blank email have been marked as favorite. Even after setting the body display to plain text it is blank. And the metadata containt

I had previously logged into my Yahoo Mail account. Still, now that I've deleted it, I'm having trouble logging in again. I don't have any extensions installed on Thunderbird, and I can't find any ad blockers or JavaScript settings. I've also cleared all Yahoo cookies from Thunderbird. Does anyone have any suggestions to help resolve this issue?

Changed my BT mail password. I can receive mail but when trying to send I am asked to enter password which is not recognised. The SMTP server does not reccognise this. I have checked other questions and all seems well in my settings, i.e. changed stored passwords, but I must have missed something.Any advice most welcome Don

Hi,

Since updating to Thunderbird 140.7.1esr (64-bit) on Windows 11, moving messages from Inbox to any folder takes about 7 seconds.

Details:

Account type: IMAP (Cogeco)

Happens in all folders

Inbox has ~600 messages (not large)

Was working normally before the recent update

Delay occurs every time moving a message from Inbox to another folder

No freezing — just a delay before the move completes

No antivirus changes

Issue started immediately after update

This appears to be related to IMAP sync behavior introduced in 140.x.

Has anyone else reported this, or is there a known regression?

Thank you.

Hallo, ich habe meine E-Mail-Konten in Thunderbird umgestellt von POP zu IMAP. Meine Filter-Einstellungen waren bisher gültig für "Lokale Ordner" (die Filter musste ich manuell starten) Wie kann ich die Filter-Einstellungen auf den Posteingang meiner IMAP-Konten kopieren/migrieren? Danke, und Grüße aus Berlin

I have added a new outlook email account to thunderbird. I have checked and have the most recent update 147.0.1.(64 bit). It added the email, I can test connection to server and passes. When I try to get or send email I get either authenticated but not conected OR Command 12 error. I have IMap setting turned on in outlook and added thunderbird as an app.

1 How can the list "recent folders" in the icon "store in" be sorted alphabetically? (sorry, my version of Thunderbird speaks German) It used to be alphabetically, but now is sorted chronologically.

2 I cordially suggest to add a function exactly like this one, but with item at my own disposal (maybe the favorite folders).

Thanks, Martin

Good afternoon, Since yesterday, I have been having a problem where new messages can no longer be previewed or opened. Emails can be sent, but they do not appear in the sent items folder. Everything works fine on my Samsung smartphone with the Samsung app.

Kind regards and many thanks, Marcel

I can't login to one of my email addresses. It says login to server with username failed. I tried all of the suggestions (using a pop server for example) and none of them seem to work. Please help.

Does TBird support plus addressing?

Scenario: I want to reply to email sent "To: markfilipak+joe@...". To do that successfully, in the "Write" dialog, I have to click on "From", scroll down to "Customize From Address...", click it, and add "+joe". (There is a menu alternative: "Options","Customize From Address...".)

If I forget to do that, then my reply does not have "+joe"; it goes out "From: markfilipak@...".

The Issue: When Joe replies to _that_ message, it does not have "+joe", so Joe's reply is trashed. (It's trashed because a filter I wrote automatically deletes messages that do not have "To: markfilipak+<something>@..." in the header.

The sensible way to handle plus addressing is for TBird to recognize plus addressing and to automatically make my "From" header from Joe's "To" header. That way, "+joe" will always be there.

Is there a way to do that?

Thanks Folks! -- Mark.

I am trying to create my outlook.com account in Thunderbird. I see the Account Hub box, and have typed in my email address. But when I type in the password, I get an error message, "Authentication failed. Please check the username and password". It then says, "Exchange auth error". I have checked and double- and triple-checked the spelling in the email address and password, and signed in to my email via the Microsoft outlook.com page using the same email and password. I can sign in to my email using the latter method, but Thunderbird keeps giving me the same error message and won't create the account in Thunderbird. What am I doing wrong?

Hi, I have followed the instructions for incoming and outgoing servers to convert my Juno Webmail to AN MBOX FORMAT and bring it over to Thunderbird. However, it is not syncing up to Thunderbird and bringing in all of my old emails from Juno.

Any help you can offer with this situation would be greatly appreciated.

Thank you

Carla
