My name is graeme , my wife Olivia.

I have many many messages from various people; if I reply to a a mail from "fred", Thunderbird creates a mail:

to: fred@xxxx from: graeme@xxxx

I have several messages from my wife , that behave in this same fashion (ie , as you would expect) but ONE message, when I reply the message displayed in Thunderbird (ie NOT YET SENT, so no SMTP etc yet involved) says:

(it does NOT have a REPLY-TO header BTW)

to: graeme@... from olivia@.....

...I've search back though my mailbox and all the mails from my wife work as you would expect, bar this one ...AND ONE OTHER that I found:

This says:

from olivia@.xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

When I hit reply , it generates a message:

from olivia@xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

So the from and to in the reply are exactly the same as the from/to in the initial message (they are not swapped)

So, to be clear 99% of messages are fine, it's just one or two cases where I get this odd behavior.

今日Thunderbirdのメーラーを開いたらメールフォルダが英字表記に変わっていました。 具体的には「受信トレイ」は日本語のままなのですが、「送信トレイ」が「Sent」になり「迷惑メール」が「Junk」に変わるといった感じです。 受信トレイ以外はすべて英字表記になっています。 設定にある「言語とフォント」は「日本語」のままで変更はありません。 元に戻す方法をご存じの方がいましたら、ご教示をお願いいたします。

i can not receive mails, since the update to 128.5.2ESR not on imap.strato.com not on imap.gmail.com not on mail.yourhosting.com

just since today after the update. sending emails seems to work.

I did NOT change anything in the accounts.

How to solve????

Thank you.

Hi,

I'm trying to add another account to my Thunderbird client (already have 2, a IMAP account, and a Hotmail/Live/Outlook), but i keep getting the error "Exchange auth error" and no possible way to manually configure the server or anything, despite the mail server not being an exchange server. Following this, it just freezes the view, although i can close the popup by pressing escape.

is this a bug in the most current version of Thunderbird, or am i doing something wrong?

My local folders are missing. There is nothing in my profiles to recover from. This is the second time this has happened after a Thunderbird update. Last time the local folder were found in my profile and I was able to restore them, This time there is nothing to restore. Has this happened to other users?

I made a mistake. I had 128 and went up to 140. It pretty much looks the same, but a big difference is an extension I always use says it will not work with 140. I don't care how good 140 might be; if I can't use my app, QUICKTEXT, then I don't need this. How do I go back to 128 or to a version that works with my extension?

Thunderbird ver 140.0 (64-bit) on Windows 11.

Brand new, fresh installation of Thunderbird. - Added a GMail account. That worked. - I tried to add an account with my personal domain. I enter my name, the email account, and Thunderbird gets stuck in an unending loop looking up the configuration. - Other email clients have successfully looked up the config and did the setup without a problem. - The email account is handled via IONOS.com servers. - If you gave me a manual setup option I could handle it but there is none; TB goes straight into trying to handle it itself.

Any ideas?

TY, Frank

On January 21st 2025 I changed my Spectrum account password. Almost immediately Thunderbird could not log into the spectrum maintained "mail.twc.com" server. When I called Spectrum support I was told the old Spectrum use of separate passwords for SMTP and IMAP was changed to use the same password as the spectrum web page which is now the same for all spectrum logins, a "one password to rule them all" scheme in November 2024. I changed the passwords in Thunderbird for IMAP and SMTP, but it still will not connect. If I do an auto populate attempt, the server actually responds with the correct setting so I know I am reaching the server. After five days trying to resolve the issue with Spectrum I was told this is a know issue with Thunderbird and it is not the server but the third party application. It is bad enough they reconfigure things like this without disclosing it. It baffles me that the changes they claim were made in November 2024 only make themselves known when the service stops working nearly three months after the change and only when I changed the web site password. Anyone know how to solve this? Thank you so much in advance.

Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!

Recently moved to Linux Mint with Thunderbird 140.5. It's a new experience. Thunderbird has downloaded all my emails and folders from my Outlook.com account. Can send, receive, edit emails no problems and all is visible from Outlook client on other machines. Thunderbird does not show my calendar entries or contacts. I do not wish to import from Outlook as I would like to access my Outlook.com from several locations. Been through online Help articles. Nothing seems to work. Have installed TbSync and Lightning Calendar Tabs add-ons with default settings. I have tried suggestions provided in this Mozilla Support. Other forum suggestions don't seem to relate to the version I have.

I'm sure it is something simple as everything else I have done with my new environment is working wonderfully. Thanks in advance.

Have a folder on my yahoo webmail account with >100K emails accumulated over time. The emails are of no lasting value

I just received a notification (via a banner on yahoo webmail when I log in) that my storage is full (never seen this before, but not surprised that Yahoo would be looking for "additional storage" revenue - not interested.)

I'm attempting to delete the emails in this (large) folder (which are of no lasting value), so far with no success.

The initial problem is that yahoo's functions to expunge (permanently remove) the emails (after moving them to their trash folder) does not work (either 0% progress overnight, or progressing 0-100% progress, in either case all of the emails remain in their trash folder and I continue to be notified (by the banner at sign-in) that email storage is full (and I do not wish to purchase any additional storage from yahoo.) As this is a non-premium yahoo account, no support exists.

It appears that yahoo webmail does not expose their trash folder via imap (it appears empty on imap view). Thunderbird "empty trash" on the hosted Trash folder shows no contents and completes immediately with "emptied trash".

I've now tried moving emails from yahoo's trash folder to another (new) folder on yahoo webmail, then using thunderbird imap to move those emails from yahoo to a local folder. My expectation was that "move" means gone from server, present on client. That appears not to be the case.

While this step does create a local copy, a copy appears to be left in yahoo's trash folder which still cannot be removed, so the core problem (of their impact on yahoo webmail storage) is unresolved.

I understand that "expunge" exists in IMAP but I don't see how this can be used with Thunderbird.

As I'm somewhat going in circles trying to solve this problem, I'm reaching out here for advice.

Thanks

I have been using Thunderbird for many years. I have 4 accounts that have all been set up and working fine. This morning the 2 yahoo.com accounts stopped working. I logged in to the impacted accounts using a web browser and password just fine. I then updated Thunderbird to 116.0 to see if that would fix the problem, but it did not. The outlook and gmail accounts are working fine, for now.

When Thunderbird attempts to download mail for the yahoo accounts, I get a large pop-up window with "Edge: Too Many Requests". The pop-up window is blank except for that error message. I get the small pop-up with the Authentication Failure message. Sometimes I get Retry, Enter Password or Cancel. But I never see a window that will allow me to enter my password.

I can send/receive mail from the accounts while logged in via a browser but authentication fails within Thunderbird.

My Sent folder disappeared. How do I restore the folder with the sent messages still intact. Or, at the least, just restore an empty Sent folder. The In-Box, Drafts, and Trash are still there.

All the settings are correct, and it seems that because there's no Sent folder I cannot send an email. When I try to send a message I get the attached Error.

My local phone company routes email through Yahoo Mail, then to Thunderbird. It was all working fine until my Sent folder disappeared. Now because of the missing Sent folder I have to create the email message in Thunderbird saving it in Drafts so I have a record. Then, I have to copy it and send it from Yahoo Mail. Needless to say this is a pain in the you know what.

Can someone please provide the instructions to get my Sent folder back?

Thanks,

Tess

I’m using the Windows 11 version of the Thunderbird app, but when I try to add my Outlook account and enter my password, it shows “Authentication failed. Please check your username and password,” and I can’t complete the Outlook setup. I’ve tried changing my Microsoft account password and entering an app password, but neither worked.

Guten Tag, ich arbeite mit Thunderbird auf Linux Mint. Jeweils in den aktuellsten Versionen: Linux Mint 22.1 Cinnamon Thunderbird 128.11.0esr (64-Bit)

Auf meinem bisherigen Rechner begann Thunderbird mit dem letzten Upgrade von Linux Mint langsamer zu laufen. Da ich mir nicht anders zu helfen wusste, habe ich in einen neuen Computer investiert. Obwohl der Rechner jetzt deutlich performanter sein sollte, hängt Thunderbird mindestens genauso wie vorher. Zum Teil ruft Thunderbird auf dem neuen Rechner auch keine neuen E-Mails mehr ab. Ein Neustart korrigiert das zwar wieder, aber beim nächsten Start kann es dann wieder genauso sein.

Alles, was man in den Foren findet, um Thunderbird schneller zu machen, habe ich erledigt. Cache gelöscht, im abgesicherten Modus gestartet (da ist Thunderbird genauso langsam). Auch verschieben von Nachrichten in Archivordner brachte keine wirkliche Besserung.

Ich nutze Thunderbird für 7 Kalender (zum Teil lokal) und 10 E-Mail-Adressen bei unterschiedlichen Anbietern.

Als Add-on habe ich DKIM Verifyer installiert und aktiv.

Ehrlich gesagt, bin ich inzwischen ziemlich verzweifelt, was das Thema angeht. Witzigerweise lassen sich die Entwicklerwerkzeuge nicht aufrufen. Keine Ahnung, ob das vielleicht ein Indiz für den Fehler sein könnte.

Hat jemand eine Idee? Oder noch Fragen?

Herzlichen Dank.

Trying to set up Thunderbird on new computer. I do NOT want to import anything but address book from old computer. I use Thunderbird to Gmail since I also have an Android phone and want to access emails with Thunderbird and Gmail. I downloaded the Thunderbird installer, but I cannot log into Gmail when the Thunderbird setup asks me to EVEN THOUGH I know I am using the correct Gmail password, it is rejected as incorrect. Do I need to set up a whole new Gmail account? I MUST use the same email address, and I doubt Google will allow me to set up a new account with that address.

Please help.

Others have mentioned this but I'm not sure if there is a fix/anything is being done. The threads are all from previous Thunderbird versions.

I use Thunderbird for work. I have to find specific emails and folders - get to them quick. I am no longer able to do this. It's really distressing.

This is something really basic, that should be the default or else really easy to change.

I'm on a Windows machine and using Thunderbird 140.3.0esr. I've been using Thunderbird since 2003 and never had any problems. Now I'm panicking!
