Since yesterday when I open Thunderbird to check my bigpond emails on my laptop I get a message that says "Enter your password for mail.bigpond.com" - I've never had to enter a password in all the many years I've been using Thunderbird on my lap top. I can get the emails on my phone and on Telstra webmail but I prefer Thunderbird. Also get a message that says "Mozilla Thunderbird login timed out" When I put in the password I use for Telstra webmail it says "Host contacted sending login information" but then I get another message Login to mail.bigpond.com with user name [redacted] @bigpond.net au failed Retry...

Not sure if this is connected to not getting emails on my phone for a week and going in to Telstra yesterday where they fixed that problem...

I have two accounts set up in Thunderbird using POP settings. I'm having trouble with email from one of the accounts being downloaded into both of the inboxes.

Any idea how to remedy this?

Thanks!

My two Optimum email accounts (POP3) stopped sending messages. See attached error message. They are still working on a different computer with the exact same settings and Thunderbird version (Windows 10 on both too). I also have Outlook and Gmail accounts all still sending fine. Sending from troubleshooting mode and clearing the startup cache didn't help. Any clues what I can try?

Mac OS 26.7.1.

There are 2 responses to IMAP command 103. IMAP command '104 IDLE' between the 2 responses. The first one is correct. The second one!!! is identical to the first one except it is prepended with the letter 'p'!!!. Always the letter 'p'. It looks like a programming error.

Note that the entry in prefs.js for this main account is broken since migration for Thunderbird 155.0.1 to 156. Every time I change some settings in the Identity section, 2 prefs.js entries are removed: mail.identity.id1.fullName and mail.identity.id1.useremail. This prevents me from sending emails from this account until I enter the proper values from the Prefs editor. I realize this is 2 problems but I think one may cause the other. Note that I have a second Yahoo! account that works perfectly well.

Thanks for any advice.

I currently have spectrum service and have gone through this with them. Everything is fine on their end. TB is throwing this message when I try to send an email.

"Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

It all worked fine until last week.... Once this started, I changed all servers / ports etc to the settings Spectrum suggested to no avail.

Any ideas?

I sent email, email goes out from thuderbird but copy is not saved is "sent mails", its only for one receiver, for all other it works, why? before it work for this receiver too

A few days ago, when I opened Thunderbird, it began downloading all folders and emails from my server provider ( bringing the folders to date) I already removed the account and the database twice to see if it was a database issue, but it keeps refreshing all my folders and emails, which is a huge amount and takes a long time to complete. Any idea how to troubleshoot or fix this? Thanks

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?

When I move messages I want to save to local folders I have created, sometimes they are greyed out, and back in my Inbox

This also happens in the Sent folder

I have had problems accessing my email server (EveryMail). Problem started about 2 weeks ago. Was no problem before. I am using unified folders. Sometimes a folder property (inbox for instance) shows all email accounts but nothing selectable. Other times an account might have only inbox selectable, other times all account labels are visible. Selecting options for deleted folder only shows inbox for most email accounts. Similar for spam.

WIN10のPCで、Thunderbirdを長年使用してきました（ささやかに寄付もしました）。３年前に故障したのでHPのPC（WIN11、M2のSSD内蔵）に変え、Thunderbirdをインストールした時にはそのまま何の支障もなくメールが開通したのですが、今回多分内蔵のM2のSSDの不調でか、WIN11が立ち上がらなくなりました。他のSSDに差し替えたところ、ネットその他のソフトのインストールや動作は回復したものの、Thunderbird による so-net のメールやり取りができなくなりました。 「メッセージ受信」しても「サーバーpop.so-net.ne.jpとの接続で認証に失敗しました」となってしまいます。何回か試し、DLし直したり、「認証方式がOAuth2になっているか」確認したりしても原因がわかりません。メルアドは「kjm@cf7.so-net.ne.jp」です。一つ思い当たるのは、インストールし直した時だったかに、「パスワードを入力」という画面が出てきたことです。前回の時はなかったので、自分のメモにもありません。新たに今はパスワードを入力するようになったかと、それなりのワードを入力したものの、「パスワードが違う」とはねられました。 このメルアドはいくつもの認証先や連絡先であり、このまま使用できなくなるのは大変困ります。どうか解決方法があればお教えください。メールが受信できない相談なので、お返事はこのページに表示されるのでしょうか？ ちなみに、苦し紛れに別のメールソフトをＤＬし受信しようとしましたが、やはり「認証に失敗しました-ERR[AUTH]Authentication failed.」となって受信できませんでした。

I can not down load Emails from Yahoo to Thunderbird. Every things was fine as of Aug 26th. On Aug 27th with no changes to any system settings the Yahoo Emails would not down Load. I am running Win 10 on my system. I disabled the antivirus. Reloaded Thunderbird - no effect.

I have since deleted Thunderbird and then reinstalled latest version of Thunderbird (154.0) . I re-entered my password. I checked the OAuth2 settings and they are set as described in the support article "OAuth2 Authentication for Yahoo, AOL and ATT".

Message bar at bottom of Thunderbird screen shows: Myaccountname@yahoo.com:Downloading message 1 of 7 The emails do not down load - then after a few minutes - a no messages to download message flashes and then blank - nothing

I am out of Ideas. Anyone?

Had a problem which required complete reinstallation of Windows 11, but although I have been able to recover my Thunderbird account I cannot get new emails. I get the following notifications: "Temporary authentication failure" and "Account is temporarily unavailable". When trying to sign in using "Forgot password", I never receive the recovery email. What do I do now?

Using the get new mails button or the time interval setting may find some messages but not all. The imap mail server is mailin.telia.com. I have been using Thunderbird for several years without such issues until now several months ago. Are there any new settings I should be avare of?

Hi,

For both servers imap.exmail.qq.com / imap.263.net, when I click on the email subject in the email list during downloading processes (many emails headers are being downloaded but email body downloading is not completed), the email is broken without any content (only header).

I go to the web email server and move the email to another folder and then move it back to inbox. Then I delete the same email in Thunderbird and donwload again the email again, it's completely downloaded with the email body.

I don't have any issue with eM client or Outlook for such issues. Any possible setting to solve this issue?

Thanks.

My emails will not download in Thunderbird. It shows a server connection but the server is fine. I can even hear the tone like emails are downloading but I cannot find them.
