Hello,

 So i downloaded TB it worked just fine until now. I can't send email anymore but i can receive them. When i try to send one, it says that there's an error with the server, it cab't connect anymore to the SMTP server. I tried to change the SMTP mail, to delete my account and reconnect. But nothing helps. What can I do? It's the only way for me to connect to my iCloud mail for now.

Thunderbird has been acting weird. For a week or so, it has sometimes been downloading only one message at a time when I hit "Get Messages." I have to keep clicking "Get Messages" over and over to download my email. Now, however, it won't retrieve any messages at all from that account. It goes through the motions, and says that there are no messages to retrieve, but there are. I have tried restarting, both Thunderbird and my computer, several times. I have tried compacting the inbox. I briefly got it working again after restarting, but it's back to not working and restarting does nothing. The online information tells me to delete my account and then add it again, but it also seems to indicate that if I do that I'll lose the email that is currently stored under that account. That's not an option! I am able to send messages, and Thunderbird retrieves messages from my other email account just fine.

I'm trying to set up Thunderbird to send messages via Google Mail.

When I send a message, it reaches Google (it's in the Google "Sent" folder), and is successfully forwarded on to the recipient. However, the Thunderbird "Sending Message" progress box never closes and only disappears when I press cancel. It is, I assume, waiting for an acknowledgement from Google that never comes. But how do I fix this? The messages are being sent but I have no way of knowing without logging on to GMail to see if it's in the sent folder.

I am working on my Windows 11 where I have TB synced with a Comcast account and a frozen GMAIL due to the need to free up space. Under GMAIL I had to look up older messages for recipients before sending the message I prepared with the attachment. I used my Comcast email as the address in the cc: line; but did not realize that I was still in the GMAIL before I hit Send. Why did it bother to send? Now that I sent it, I do not have a copy. A box appeared that said that it would not make a copy. I understood what the problem was; but it gave me no chance to change the account at the top so that TB could copy it to my Comcast folder. How can I retrieve this message?

I have a request.

Please make it easier to send feedback to the developers.

I don’t want to have to log in to the forum every time just to ask someone who might not even be an expert.

I’m Japanese and don’t speak English, so the English forum is difficult for me to use.

It’s a hassle to have to post on the forum like this just because I can’t easily send feedback in my local language.

I have two pieces of feedback I wanted to share this time.

1. Sometimes when I open Thunderbird, I get an error message saying it can’t load because there are too many accounts. Is this because it’s trying to check them all at once?

Please have it load them one by one in order. Or, please add an option in the settings to do this.

2. Messages marked with “Re:” are replies, right?

Let’s say my account is “Apple.” If I reply from “Apple,” a message marked “Re:” should remain in the “Apple” folder. From the recipient’s perspective, replies to emails from “Apple” should also come from “Apple.”

However, there were emails where I was recorded as having replied from a different account, even though I don’t recall switching accounts when replying.

So, from the recipient’s perspective, it looked like the email came from a stranger, and they replied asking me to identify myself.

While it’s not impossible that I might have changed the address by mistake while half-asleep, I’m reporting that there were instances where I was recorded as replying from a different address even though I don’t remember making a mistake.

I just want to share a request and a report, so there’s no need to reply.

今回送りたかったフィードバックは二つです。

1、サンダーバードを開くと、アカウントが多いからロード出来ないとかエラーメッセージが出てくることが時々ありますが、一度に確認しようとするからでしょう？

一つずつ順番に読み込むようにしてください。 もしくは、設定で、そのように出来るようにしてください。

2、Reが付いているものは、返信したものでしょう？

アカウントがリンゴだとします。 リンゴから返信したら、リンゴの中にRe付きのものが残るはずです。 相手からしたら、リンゴから来たメールの返信もリンゴから来るはずです。

しかし、返信する時にアカウントを変えた覚えがないのに、違うアカウントから返信したことになったメールがありました。

なので、相手からしたら、知らない人からメールが来たことになり、誰だか分からないから教えてくださいと返信が来ました。

ねぼけて返信時にアドレスを変更した可能性も0ではありませんが、間違えた覚えが無いのに違うアドレスから返信したことになったものがあったことを報告しておきます。

I have three separate Yahoo email accounts. I set up Thunderbird to link to each Yahoo email account separately. It worked fine for a year or more. On 5/25/26 one of the three Thunderbird email accounts stopped downloading emails from Yahoo. I could see at the bottom bar Thunderbird indicating that is was downloading 1 of XX emails, but never actually downloads them. There is no error message. I checked the Yahoo email account to verify the number of emails I am missing from Thunderbird and the number is correct. I can see the emails in Yahoo. I'm the only person using Thunderbird, so no changes have been made to previous settings for retrieval. I confirmed Security and server settings for Thunderbird in and out going emails, and Yahoo are correct. I tested the connection in Thunderbird, and the connection is successful. I tried to send an email from the Thunderbird account having issues, and the email was sent and received by the recipient. The recipient replied, and Yahoo received the email, but failed to download it to Thunderbird...along with all the other emails since 5/25/26. I unlinked the account and reestablished the link between Yahoo and Thunderbird, and still not fixed. I tried restarting the computer, with no change. I tried to send an email from Thunderbird to one of the other Thunderbird emails and it was sent and received. I made changes to Thunderbird to force the download of emails, and it still wouldn't do it. I turned off my antivirus, closed Thunderbird, and restarted it, and that didn't change anything. The capacity of emails on the email in question only has 739 emails, so it's not over the limit and I have plenty of storage capacity. Thunderbird is set to save emails, Cookies and cache were cleared, no change. I ran the folder repair feature in Thunderbird, but there was no change. I compared all the settings between the other Thunderbird emails that are working against the one that isn't, and they are all the same. There was a suggestion to close out of Thunderbird and delete the "Global-message-db.sqite" file from the Thunderbird profile in case it was corrupted, and it would recreate this file when Thunderbird was restarted. The file was recreated, but it didn't fix the problem. There was mention that a suspicious email in Yahoo might be blocked by Thunderbird, so I placed various emails in the spam folder, and it didn't work. I did find one email in the Yahoo spam folder that was dated before 5/25/26 and moved it to the Yahoo inbox. Lo and behold, that one email downloaded to Thunderbird. So there is something within Thunderbird preventing emails from downloading after 5/25/26. I've read many people complain about similar download failures with no solid fix. Someone mentioned it fixed itself on a day, but then stopped again days later. Someone else mentioned Yahoo changed its password protocol to transfer emails, but that doesn't make sense since the other two are still downloading based on the "old" password protocol. I'm at wits' end. Thanks for reading all of this. I hope someone has a solution.

I have Thunderbird 146.0.1, using 6 email accounts with POP. Two questions:

1) Whenever I start Thunderbird, it retrieves only a subset of the email accounts which I have defined to Thunderbird. Some accounts retrieve ALL, and other accounts retrieve NONE. I also have the extension "Get All Mail" and when I click that it retrieves ALL the email, including the email that the Thunderbird base program didn't retrieve. How can I get Thunderbird to get ALL the email?

or alternatively...

2) Can I somehow disable the Automatic Retrieval of Email when I start Thunderbird? ... and rely solely on the "Get All Email" extension.

Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?

TB connects to Yahoo Plus just fine. Folders display but no emails display?? I fixed this once a while back by deleting config files in TB and re-adding Yahoo. It has happened again?? Forgot which files I wiped (in Linux Mint). Anyway to avoid doing this continually and what's the fix?

Hallo Zusammen,

bei der Neueinrichtung auf einem neuen Rechner fehlt mir der Ordner für gesendete Mails.

Ich habe die Anwendung auch schon komplett deinstalliert und wieder aufgespielt. Hat sich leider nicht geändert.

Was kann ich noch machen?

Beste Grüße

Bonjour,

Je viens de recevoir mon nouveau PC et je souhaite utiliser THUNDERBIRD comme client mail. Mais lorsque je rentre mon identifiant et mot de passe. Il me dit que ce ne sont pas les bons alors que je verifie sur MOZILLA mon id et MP et tout semble correcte car je peux me connecter sans aucun problème. Pouvez-vous me dire d'où vient le problème, s'il vous plaît ?

Hello, I need help with getting Thunderbird email installed on my MacBook Air 2017 macOS Monterey. I have successfully installed the app on my desktop but, each time I try to finish the set up, I get an "Authentication Error" with "Unable to log into the server" on the Welcome to Thunderbird initial Pop Up screen. I think it might be with the Yahoo server but, I do not know. Could someone help walk me through the set up? Please let me know as soon as you have a few minutes or, direct me to the appropriate support department. Thank You, TL Shaffer

I have been using Thunderbird for YEARS, with 3 separate email accounts. Great product.

Just recently, with out warning, my [edited from public] @ sbcglobal.net account stopped being able to send email. I can still receive emails. I have not changed any outbound setting. Any help appreciated.

With previous computer (Winidows 11) I've been able to send an email from WITHIN Word, but now I get error message "Word couldn't send mail because of MAPI failure." Any idea how I can fix this? Regards, David, running TBird version 151.0.1 (64-bit)

I have two email accounts (one is imap, one is pop3) in my older version of Thunderbird. They have both worked normally until last week. The pop3 account continues functioning normally, but now when I select (in Thunderbird) the imap account, the mouse cursor starts showing the hourglass and the bottom status bar reads "loading message" . I've closed and restarted Thunderbird, but this doesn't make any difference. The imap account is stuck on "loading message" and doesn't download anything. I also checked my imap email account on the ISP's website, there is new email there waiting to be downloaded,. What can I do to troubleshoot this?

ps...a few weeks before this problem surfaced, I had all my email (inThunderbird) disappear, so I renamed the prefs.js file and that fixed the problem. My email worked normally after that, until this current problem occured.

How do I add my Comcast email account to Thunderbird now that it has switched to Yahoo? When I try to add it all I get are the Comcast mail servers in the setup program to add an email. When I try to edit it and change it to the Yahoo mail servers it does not work. I have used Thunderbird for many years and Firefox for a browser. When I started on the internet I Used Netscape. Firefox and Thunderbird were started by Netscape programmers if I remember right. I love both Thunderbird and Firefox and don't want to change but the way it is now I cannot use Thunderbird for email. I have tried both Pop3 and Imap setups. Neither will either allow me to set up my email in Thunderbird to get email from Yahoo. I do not like the Yahoo Website for email.

ヤフーメールがセキュリティを強化する為に運用方法を変えたようでサンダーバードでヤフーメールの受信が出来なくなりました。 行った対策は行った順に ⓵サンダーバード側の保存されたパスワードの削除。再入力 ➁ヤフーメールのパスワード変更 ➂ヤフーメールの受信設定などの有効化 ➃サンダーバードの再起動 ➄サンダーバードアンインストール＆再インストール ➅アカウントの再設定 です。 ➂までで送信やヤフーメール以外のアカウントのメール受信は出来るようになったものの➄まで行っても結局pop.mail.yahoo.co.jpサーバーへの接続は出来ずエラー＆パスワードの再入力の無限ループでした。 又⑥ではヤフーメールのパスワードのみ旧or新パスワードどちらもパスワードが違うと弾かれアカウントの再設定が出来ませんでした。

対処法をお願い致します

I get the following message when I try to download emails "Unable to write the email to the mailbox. make sure the file system allows you write privileges and you have enough disk space to copy the mailbox

Desktop Thunderbird no longer downloads mail from Yahoo though it did until 2 weeks ago or so. Now when checking for mail, I only see a "Local Folders: Checking Inbox for new messages" (screenshot) that eventually disappears after a while with no download. I can still send messages out from Thunderbird through Yahoo. I have done the "Please check the following before asking for support" : 1. I can log into my Yahoo account via the web and am using the same password 2. I only have one Yahoo account; all the other accounts work fine 3. I can send mail from Thunderbird through my Yahoo account with no problem 4. OAuth2 is active and can successfully establish a secure connection (screenshot) 5. Cookies are enabled with no exceptions (screen shot) 6. I do not use a VPN 7. Version is 151.0 (screenshot) 8. I checked the Error Console messages when Checking Inbox was active (screenshot) but do not understand it

I blocked out information on non-Yahoo accounts and email subjects on screen shots
