Hallo, ich habe seit 2 Wochen Probleme mit der Authentifizierung meines Mailaccounds von AOL. Alles was ich Versuche funktioniert nicht. Ich bekomme jedesmal im eingeblendeten AOL Autentifizierungs Fenster die Meldung "etwas ist schiefgelaufen. Ich habe in meinem AOL Account schon mehrerer Male ein App Passwort für Thunderbird erstellt. Habe dieses App Passwort Thunderbird genannt. Konto ist ein SMTP IMAP Konto, die Ports stimmen auch. Ich habe mein AOL Mailkonto mittlerweile in Thunderbird komplett gelöscht und ebenfalls die AOL Passwörter gelöscht. Die Authentifizierungsmethode für outh2 ist angewählt und Cookies sind eingeschaltet.

Ich kann machen was ich will. Die Autentifizierung funktioniert nicht.

Woran kann das noch liegen. Ich bin mittlerweile ratlos.

Bonjour, j'utilise Thunderbird depuis plusieurs années et j'ai plusieurs comptes de messagerie. Je suis à la version 140.7.1esr. Depuis plusieurs jours, j'ai le message "Saisissez votre mot de passe pour alain.jouenne1@orange.fr". J'ai beau saisir le mot de passe, rien n'y fait. Ma config est Windows 10 64 bits, 3 adresses Gmail, 2 adresses Wanadoo et cette nouvelle adresse orange qui me pose problème. A noter, lorsque j'ai eu cette nouvelle adresse, je l'ai configuré dans Thunderbird et elle a fonctionné. Et puis, un jour, j'ai eu ce message. J'ai même modifié mon mot de passe de messagerie, mais cela n'a pas fonctionné. Pouvez-vous m'aider ? Merci d'avance

This is a new Fedora-42 desktop, upgraded (dnf upgrade) today. I installed Thunderbird today (dnf install thunderbird), after doing the operating system upgrade. I tried to add my yahoo e-mail account. Settings are as follows:

• create accounts in the new Account Hub is unchecked (off).
• accept cookies from sites is checked (on).
• remember password is checked (on).
• I'm using "IMAP".

When I click "Done", a separate window pops up in which yahoo asks for my password. After entering it, yahoo says "Something went wrong", and gives no other indication of what the problem is.

If I instead "Configure manually"... I tried both the default hostnames and "export.imap.mail.yahoo.com" for the outgoing server. I tried both "Normal Password" and "OAuth2" authentication methods.

In all the above cases, I get "Unable to log in at server. Probably wrong configuration , username or password." with a yellow background.

I see nothing of "Edge Too many requests" as was happening to several people recently.

How do I add my yahoo account to this new Thunderbird on Fedora-42?

when I view the saved passwords, the saved logins window does not work properly. I cannot drag the borders left or right to view whole information such as passwords or provider. The borders just refuse to move. I therefore can only view partial information under any heading. Please help if possible. Thank you.

hi today thunderbird started showing yahoo popup login and after adding credentials i always get "something went wrong.We could not sign you in. Try again from a different device." Also popup once closed it opens instantly.

i can sign in normally from browser. thunderbird version is 147

is there any fix about this?

thanks for any help

regards

Am having prblems authenticating oauth microsoft 365 from tbird ubuntu.. Everything was working fine but suddenly getting auth failures. Phone works fine, and all software is up to date.

I need to fix TB to send/receive/save emails after a power failure today, Grid outage at 13:40, Power restored 13:40. Computer restarted, TB opened but will not perform any send/receive/save tasks. TB Message Send gets Outlook notification - Authentication failure. Went to Outlook email, logged back in, test email I had attempted to send by TB is in Outlook, plus new emails in Outlook, but none in TB. Checked for TB updates, current as of Jan 15, 2026. Restarted computer twice. Outlook email works but TB does not perform any tasks. I lost no TB emails in my messages before the power failure, they are all still in my TB messages. I have Firefox Browser and Windows 11. I love TB. It has had cardiac arrest. Help. Ann

Have no idea to whom I was chatting a week or so ago, but outlook.office365.com was recommended to me as the incoming server setting for Outlook.com. Set TB that way and used it for a week or so. TODAY got a "failure to authenticate" error from TB (have had many such errors before). Went directly to Copilot, as I thought it would be the most authoritarian place to clear up Microsoft problems. It provided the informaiton below: Official Outlook.com Thunderbird Incoming Server Settings (2026) IMAP (recommended) Settings Server name: imap-mail.outlook.com Port: 993 Security: SSL/TLS Authentication; OAuth2 Username; Your full Outlook.com email address

Why this is the correct server Outlook.com, Hotmail, Live, and MSN accounts do not use outlook.office365.com .

Set outlook account incoming server to imap-mail.outlook.com and reset TB Immediately got: Mozilla Thunderbird Thunderbird Authentication failure while connecting to server imap-mail.outlook.com.

Can someone please tell what's going on?

I have just installed Thunderbird v146.0, set up the first mail account (POP3) OK, then tried to set up a GMail IMAP account. I inadvertently gave it the wrong password, so the Account hub throws out the connection with an Authentication error "Unable to log in at server. Probably wrong configuration, username or password".

The problem is I can see no way of amending the password; if I try and set up the account again, it just skips the "enter password" step, presumably because TB thinks it already knows the password for this email account. I have tried the following:

- The "edit configuration" feature in the account hub doesn't have a change password option - The Saved Passwords section in Settings > Privacy & Security doesn't show the Gmail creds, presumably because it failed to set up this account in the first place - I reinstalled TB, having previously deleted the Profiles folder in C:\Users\<username>\AppData\Local\Thunderbird; everything I've read on this suggests this is the one and only place where TB keeps its data. However, when re-entering TB, the POP3 account I set up is still there, so there must be somewhere else that TB is storing its data, I guess the Registry?

Am I missing something? I can't be the only person who has had this problem!

Thanks

Thunderbird says password or settings are incorrect for iCloud mail. I have tried everything AI suggested. I use a custom domain on icloud and I have even tried using the underlying icloud address as login. Nothing works. The app password is newly generated and I tried it with and without hyphens.

Please help

I didn't have a very specific name (just a set of letters, like AGDFASSFGASD) for the full name for my mail, as I didn't think much of it. But one day, either I logged out myself, or the system threw me out of that mail. I'm trying to recover my mail by trying on the correct password and email, but I don't remember my full name and most likely because of this I can't log back in.

Will any of the moderators be able to contact me via another rambler email so that I can provide the email I'm having problems with? This mail is important to me now. I don't know exactly what happened to the mail, I just can't log in to it.

great email client if you could even sign in. my issue is I have two (a whole two!) outlook accounts. I made a new profile to confirm it's not just an old profile which should not be an issue anyway and I get greeted with the original nice onboarding tool, I enter my email and click continue, it pops a window asking for my oauth2 crap and its done and setup! Perfect now I go to add another account and get a Different window/page from before, Ok cool enter email Oauth2 pops and I do that, then sends me to the password page asking for a password and "Your login" whatever that's suppose to be. entering a password does nothing but fail (makes sense since outlook only likes oauth2 at the moment) and I have no idea what to fill "Your login" with. the Continue button is greyed out and closing the login window shows it was never added.

now to make this worse this started with being unable to send an email. there is NO way that I can find to refresh the outgoing server auth token if it either expires or breaks (which does seem to happen even if it's not "suppose to"), apart from removing and re adding the account but as stated above that is also broken you can't send emails from thunderbird unless you save the draft and send it from another device that works

more testing and the "new" login tool failed and worked at the same time it didn't ask for oauth the second time I tried but worked and could send...

like it's mainly two things that are broken, the newish login tool and the inability to refresh oauth tokens if it fails I'm running linux but this happens to people I know that use this In a work and personal capacity on windows as well. like do some basic login testing at least with outlook accounts like that might be the main issue but still they are one of the big players and this is unacceptable for a email client

I had a shared gmail account for an organization I was involved with for a few years. Last May, that association ended. I deleted that gmail account off of my Thunderbird. I have no associated calendars on my TB. I have no add-ons on my TB. But every ten minutes or so, this message authentication request pops up on my screen, regardless if TB is even open. It's driving me insane. Please help.

I've had an Email account with outlook.com for years using Thunderbird. 2 days ago, Outlook forced me to change my password to login using a webbrowser. I changed the account password in Thunderbird and now I can't login. No matter what I try (and the experimental account setup is disabled), I simply get a pop-up window I guess from Outlook stating it can't log me in because cookies are disabled. I don't know which browser this pop-up is trying to use. I've got 3 web browsers (firefox, brave, librefox) on this linux mint PC. I have enabled all cookies in all 3 browsers, but the same error message occurs.

I'm using Thunderbird 140.5.0esr (64-bit) and it worked just fine until the password change. I have deleted all accounts in Thunderbird now and am trying to add my primary outlook account back. This is beyond frustrating. Hoping somebody can help.

Guten Tag,

ich nutze Thunderbird (140.6 64Bit).

Bei jedem Start von Thunderbird, soll ich ein Passwort für ein Konto "caldav" eingeben (siehe Bild Passwort), das Konto existiert aber nicht (siehe Bild Konten)!

Hat jemand eine Idee?

MfG

Wenn ich Thunderbird öffne erscheint immer folgende Frage:

Geben Sie ihr Passwort für "[edited]@bluewin.ch" auf imaps.bluewin.ch ein.

Wo finde ich dieses Passwort? Sonst kann ich Thunderbird nicht benutzen.

Mit freundlichen Grüssen Peter Mühlemann
