My spam folder has remained empty for the last 2 weeks- also, wasn't the folder called junk before? Its now labeled Spam and remains empty. The spam is just gone and not going to my regular email either. Please help.

• • Titel: Yahoo-Mail lässt sich in Thunderbird 153.5 unter macOS nicht anmelden – „Es ist ein Problem aufgetreten“**

Hallo zusammen,

ich kann mein Yahoo-Mail-Konto seit etwa zwei Wochen nicht mehr in Thunderbird einrichten. Ich vermute ein Problem mit der Yahoo-OAuth2-Anmeldung.

• • Mein System:**

- Betriebssystem: macOS auf einem MacBook Pro - Thunderbird-Version: 153.5 - Weitere E-Mail-Konten in Thunderbird: Gmail, WEB.DE, GMX und Host Europe. Diese funktionieren alle problemlos.

• • Fehlerbeschreibung:**

Wenn ich mein Yahoo-Konto hinzufügen möchte, öffnet sich das Yahoo-Anmeldefenster. Ich gebe meine vollständige Yahoo-E-Mail-Adresse und mein korrektes Passwort ein. Anschließend erscheint folgende Fehlermeldung:

„Es ist ein Problem aufgetreten. Wir konnten Sie nicht anmelden. Versuchen Sie es bitte auf einem anderen Gerät.“

Darunter befindet sich ein lila Button „Hilfe aufrufen“.

Die Anmeldung bei Yahoo funktioniert dagegen problemlos über Firefox auf demselben Mac mit demselben Passwort. Auch die Anmeldung über meinen Passkey auf dem iPhone funktioniert.

• • Bereits durchgeführte Maßnahmen:**

- Yahoo-Passwort geändert und die Anmeldung über Firefox erfolgreich getestet. - Zwei-Faktor-Authentifizierung bei Yahoo aktiviert. - Yahoo-Konto in Thunderbird gelöscht und mehrfach versucht, es neu einzurichten. - Authentifizierungsmethode für IMAP und SMTP überprüft: OAuth2. - Cookies und JavaScript in Thunderbird aktiviert. - Im Konfigurationseditor folgende Werte überprüft:

 - `mailnews.oauth.usePrivateBrowser = true`
 - `mailnews.oauth.useExternalBrowser = false`
 - `javascript.enabled = true`

- Ein Yahoo-App-Passwort erstellt und versucht, das Konto manuell mit „Passwort, normal“ einzurichten. Thunderbird öffnet trotzdem wieder das Yahoo-Anmeldefenster unter `autodiscover.yahoo.com`, wo dieselbe Fehlermeldung erscheint. - Alte Yahoo-Einträge aus dem Passwortspeicher entfernt. - Doppelte Yahoo-SMTP-Einträge gefunden und den veralteten Eintrag entfernt. - Thunderbird vollständig beendet und neu gestartet.

Nach dem Neustart erscheint teilweise sogar eine Passwortabfrage für `peterbeck127@yahoo.com`, obwohl das Yahoo-Konto nicht mehr in der Kontenliste vorhanden ist.

• • Meine Fragen:**

1. Ist ein bekannter Fehler bei der Yahoo-OAuth2-/PKCE-Anmeldung in Thunderbird 153.5 vorhanden? 2. Warum lehnt Yahoo die Anmeldung in Thunderbird ab, obwohl dieselben Zugangsdaten über Firefox funktionieren? 3. Wie kann ich eventuell verbliebene Yahoo-Anmeldeversuche oder Servereinträge vollständig entfernen, ohne mein Thunderbird-Profil und meine anderen E-Mail-Konten zu beschädigen? 4. Gibt es einen bekannten Workaround oder eine Korrektur für dieses Problem?

Ich möchte mein Yahoo-Konto wieder normal über IMAP und SMTP in Thunderbird verwenden können, ohne meine anderen Konten neu einrichten zu müssen.

Vielen Dank für eure Hilfe!

I can no longer get emails from my doctor's patient portal through athenahealth.com or athena.com Nothing with "athena" shows up in my email.

Trying to install an older vesion of Thunderbird, but keep getting this error: Could not get OAuth2 details for hostname =imap.comcast.net

I'm trying to add an email account to Thunderbird that (seems to) require Oauth2 authentication, but it keeps opening the wrong provider in the Firefox window that it launches. The email account is a professional G-Suite address, but it always opens login.microsoft.com instead.

I've checked the MX record for the domain and it correctly lists Google servers, and my laptop was able to authenticate to the correct destination just fine. I have used my desktop for work before, which is all handled through Microsoft accounts, so I suspect that there's some kind of locally cached data which is identifying O365 as the provider, but I can't find any relevant settings or documentation from Firefox. I also cannot find any settings or controls for the Oauth provider in Thunderbird in order to force a Google workflow.

ever since last update... can't send emails

Send Message Error Sending of the message failed. An error occurred while sending mail. The mail server responded: E5rTxqhwZYbiPE5rUxBTZm DMARC Policy Enforcement: https://postmaster.comcast.net/smtp-error-codes.php#ODM00001. Please check the message and try again.

For years I have been attaching message files, pics., etc. by clicking the Attach button and browsing to the target. Now I have to drag and drop the attachments as the Attach click is useless.

Mozilla Account works normally directly inside Firefox, but logging into Mozilla Accounts through Thunderbird's Add-ons manager fails during the Firefox handoff.

Steps to reproduce: 1. In Thunderbird Add-ons, click Log in. 2. Thunderbird redirects to Firefox, showing "Continue with Mozilla account". 3. Click Continue -> Firefox displays "You could not be logged in. Please try again."

Troubleshooting already tried:

• Created a brand-new Thunderbird profile (thunderbird -P) — same failure occurs.
• Cleared cookies/site data in Thunderbird and cleared Firefox cache.
• Disconnected existing Thunderbird/Add-ons connections from Mozilla Account dashboard.
• Extensions and add-ons themselves install and download normally.

I'm using a mailbox.org account with TB. I'm receiving messages from it, so I'm logged in, but TB keeps asking me every so often to login again, and it has three popups in a row each time. How do I turn this off?

I was adding some filters for senders to move emails to my local folders and such, and then I ran the filters. For whatever reason, when I ran the filters this time, thunderbird also seemingly deleted all emails from some of my web email inboxes. The only one that wasn't affected by this inbox wipe was my school email(gmail provider). How can I prevent this from happening again?

When I send a message the send box does not close. It remains open and says it is saving the message in the sent folder. I then have to quit thunderbird in order to close the box and get back to using thunderbird again. It does save it in the sent folder. but the box remains open Why is it doing this?

Sorry for long post. Struggling to get backup done, running out of time and other things in life now getting really urgent . Got my Yahoo Mail headache again today. Please can someone advise me? Thunderbird 150.0.2, Mac OS 10.15 7 Catalina, 2018 Macbook Pro.

Not tech-savvy so finding it hard to find what settings to use in TB. Other people's post answers always seem to show dialog options I'm not seeing on my computer

AIMS: - Prevent folders from deleting in my backup, if I delete stuff on Yahoo. - Backup Yahoo emails to a stable, local copy on an external drive, so I can access old emails + attachments independently without it trying to reconnect / synch with Yahoo Mail - After backup, delete more mail to reduce YM storage from 39GB to less than 15. Feel reluctant to do this yet, as I already lost a big folder of work from my backup by trying to muddle my way through this. - Ideally would like to end up with a local copy I can access in Mail Backup X What I've tried; - Backup using Mail Backup X. Took 18 hours and some large folders were incomplete so I tried again after splitting them up in Yahoo Mail. I liked the software but something went wrong on the 2nd try and it now won't connect to Yahoo at all. Deleted and replaced 3rd party password multiple times. Server details are accepted, but then the icon just spins endlessly, hence trying Tbird instead. Deleted the MBX account which meant no error logs available (Yes. I should not have done that). - Tried both IMAP and POP backup using TBird - have added TBird ImportExport add-on but have no idea what settings to use, advice welcomed Questions/assumptions that may be wrong: - Was advised to use server export.imap.mail.yahoo.com, what's the reason for this and would it work? Can't remember if Yahoo allowed me to enter this setting. Sorry, hard to recall as I tried so many times. - POP only backs up 1 folder - Inbox. Really?? that's not a solution then - TBird's default is IMAP so surely it would always try and connect to synch, and so would any copied backup accounts? - if I get the ImportExport add-on settings right, can I *really* achieve the goal of a local offline backup I can trust, that I could keep on an external drive and access later via Mail Backup X?
