Thunderbird Community Forum

Yesterday while using Thunderbird on Samsung android phone the contents of my inbox completely disappeared. I searched Thunderbird's other folders such as Trash, Spam & Archive et al to no avail. This is disasterous for me. I see from a Goggle search that this is not uncommon.

Thunderbird 158.0.1 (64 bit) Thunderbird codename Meadow, Mozilla Thunderbird Snap for Ubuntu-snap-build - 1.0

Running on Ubuntu Linux 24.04

Problem downloading emails from Yahoo

For years there has been no problem, but about 2 weeks ago downloads stopped. Pane at bottom of Thunderbird says downloading message 1 of 292, but is is stuck at 1 and nothing downloads.

Today something different is happening, it downloads the first 80 messages then returns again and downloads same messages again, then repeats. I now have 17 duplicates of these same 80 emails just in the time to write this and it is still downloading the same 80 over and over again.

I have searched internet for solutions. I have done the following:

Updated to Oauth2 through Yahoo website. Thunderbird shows a saved login password oauth://login.yahoo.com, plus my correct email address, plus an OAuth2 password

Checked all server settings. All correct, e.g, pop.mail.yahoo.com Port 995 SSL/TLS security, and OAuth2 authentication method

From server settings page I tested connection to server which came back successfully

Same as above for outgoing server.

I have ample disk space on my computer and ample data capability on Yahoo account.

Confirmed not in offline mode. Confirmed cookies and javascript enabled.

BTW, I can access all my mail on Yahoo’s web page, but that is inconvenient. I really prefer access through Thunderbird.

I have deleted global-messages-db.sqlite and Thunderbird reestablished it. Did the same for popstate.dat, and inbox.msf

I even uninstalled Thunderbird and reinstalled it but no improvement in the problem.

I am out of options now. What to do? Thanks so much.

I followed the instructions in the aritcle on the search page and it still didn't work. I worked with Geek Squad. They completely did all kinds of different settings and they all failed. When I click the test button, it says it connects successfully.

It tells me to retry or update the password.

I am absolutley typing in the correct password.

Hallo,

ich bitte um Hilfe, seit dem letzten Update von Thunderbird auf 159.0 (64-Bit) sind meine Mailaccounts verschwunden. Eins konnte ich wieder einrichten, das von T-Online bringt als Fehler ständig "Fehler bei der Authentifizierung" obwohl alles korrekt ist. Thunderbird kann sich automatisch die Serverdaten für IMAP holen, aber sobald ich das Passwort eingebe kommt der Fehler. Das Passwort habe ich jetzt bereits geändert, dennoch funktioniert es nicht. Was kann ich tun?

So long as I investigated, the problem is,

After version154, received emails in Japanese encoded by 8bit causes misconversion (mojibake). Emails encoded by base64 is not misconverted. Only 8bit encoded shows the problem. Version153.5 is no problem. Version154 and newer shows the problem.

Here are OK/NG by sender/receiver combination. Sender version154 8bit - receiver version154 - NG Sender version154 base64 - receiver version154 - OK Sender version154 8bit - receiver version153 - OK Sender version154 base64 - receiver version153 - OK Sender version153 8bit - receiver version154 - OK Sender version153 base64 - receiver version154 - OK

Emails encoded by base64 is OK, but some senders can encode by only 8bit. I cannot find how they can use base64. It would be helpful to know to use base64 encoding in version154 (or later).

However, the best way is that version154 (or later) can read 8bit encoded email in Japanese. I would like to thank anyone who help the problem.

I am getting this message. 'Sending of the message failed. The message was not sent due to exceeding the allowed number of recipients. You’ve reached your sending limit. Don’t worry, you can send again soon.

Is something wrong with the system?

The instructions at [http://mzl.la/1ApHx1w|http://mzl.la/1ApHx1w] did not help. FYI: I have TWO "Spam" folders?!?! Could this be the problem?

Beim Eingeben von Text in ein E-Mail springt der Cursor in das Erinnerungsfeld und stopt die Zeicheneingabe. Das ist sehr störend und verhindert flüssiges Email schreiben. Ich verwende Firefox und Thunderbird auf einem Windows PC der die Bedingungen für Win 11 nicht erfüllt und dem ein Win 11 trotzdem installiert wurde weil entsprechende Anpassungen vorgenommen wurden. Danke für Ihre zeitnahe Rückmeldung

When I attempt to send an email in Thunderbird I get an extensive string of gibberish that I have to delete before I can send the email. What can I do to get rid of this huge irritation? Thanks

I have Mozilla Thunderbird Meddow 158.01 . I have registered my name with Mozilla inserted my name in the dialog box turning "Their network" to "Your Network" . I put in a primary password to keep out hackers, Mozilla still wouldn't work. A friend suggest I change the primary password, still didn't work. I switched things around trying to get Thunderbird to work. Thunderbird still couldn't send or receive.

Recently there was a Mozilla update Immediately after that, I found thatmy outgoing email messages failed I got an error box saying two things 1 - a header saying: "Password required for Outgoing (SMTP) Server smtp.dsl.pipex.com" 2: an insruction saying: "Enter your password for "My.email.com" on smtp.dsl.pipex.com" - and a texy-box for this suppode pasword WHER do I enter it / WHY has it changed / .. as I cannot easily find the box or page to insert this password, which I do not recollect seeing before

Oh yes .. "Thunderbird version in "thunderbird App Menu - invisible on my screen

I have this problem since a couple of days, it is new . When I move my emails in local ordners then they stay in the web.de Inbox on the server and in the app. What can I do that they are automatically deleted when I move them in local ordners?

It has been some days that any email I reply via thunderbird is not saved/copied in the "sent" folder, although I checked both "sent" folder and “Place replies in the folder of the message being replied to”。

It was all OK before: my replies were in both "sent" folder and in the tree of inbox. However, now my reply only shows in inbox. The only way I find now to have my reply in the "sent" folder, is to uncheck the "Place replies in the folder of the message being replied to" option, but I want my reply in both folders as how it was before.

This is extremely annoying, as I can't know if the email has been correctly sent or not. How can this be fixed?

Hilfe bitte: Seit heute "Anmeldung auf dem Server secureimap.t-online.de fehlgeschlagen". Vorher Funktion jahrelang ohne Fehler.

Since upgrading to a recent version of Thunderbird ESR (a few weeks ago), I regularly receive notifications of error for a Yahoo mail account. I do not receive these notifications for other mail accounts. The notifications are as follows:

• The current operation on 'inbox' did not succeed. The mail server for account example@yahoo.com responded: p.
• The current operation on 'inbox' did not succeed. The mail server for account example@yahoo.com responded: UID FETCH completed.

I have deleted and recreated the account to no avail. Searches for similar issues has revealed nothing of use.

Any idea what is going on?

Version: 153.5.1esr (64-bit) OS: Windows 10 Language: English Proxy: None Email connection type: IMAP Authentication: OAuth2 Connection security: SSL/TLS Encryption: None

Every time I send an email to more than 25 or so recipients, the message does not send and I need to reverify my Hotmail account. After I do that, I resend and it goes thru fine. Not sure what the problem is. Thanks,

Ron K

Dzień dobry od dłuższego czasu (tygodnie) mam problem.
