Thank you David for your reply yesterday; I don't think it will work on a Mac. Problems seldom come singly and I now find that i cant get into my wife's Thunderbird account on the new Mac Mini. But on the laptop I have no problems. Both accounts have the same addresses yet the email address on the new computer will not accept the password. Any thoughts anyone?

Sending of password for user (name) did not succeed. Mail server mail.skymesh.com.au responded: [AUTH] Authentication failed. this is the message I get and then no new mail comes, I can sign in to my skymesh account

After initial set up of an email to sign in to that email is impossible with the error message "Something went wrong" The only help is sign in from another device. This is not helpful at all!

This is particularly difficult when trying to set up an email on on an email programme such as Mozilla Thunderbird. Not but a few months ago this was never a problem as I have used this for years with Yahoo emails with absolute no problem.

This has all changed now (January 2026) making it impossible to set up an email by not being able to sign in to the account on the yahoo pop up screen.

This being tried on Linux and Microsoft windows on numerous browsers.

On one Windows computer in your pop up sign on window it just keeps saying turn on cookies in your browser but the cookies ARE TURNED ON? So it is just ridiculous.

Thunderbird won't let me login and doesn't deliver my emails. I have reset my password and still can't get my emails. How do I get some assistance on this issue?

I transferred Win 7 Thunderbird Profile (TB)to a Windows machine. It left behind all the other settings, such as when picking up/sending email, passwords are required at the IP to login, get email/send email.

QUESTION: Is there another TB area where the passwords are stored so I can copy those over to the new computer.

I posted this about a week ago, and when I come back, it's gone. That's why I am repeating myself.

A long timer ago, I was told by a user that Thunderbird does not need passwords. It does if you what to get your email. They are setting for each email user. There are 34 under the one TB.

I hope there is a transferable file because changing all the passwords and preference for each account would be the hard way.

I appreciate your taking the time to read this,

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

I migrated my Thunderbird installation to a new computer. The installation has 25 email accounts and is now requiring passwords be entered for each account including a couple of gmail accounts.

It was my understanding passwords would be migrated when using the export/import tool within Thunderbird. Is this not so?

Do I now need to change passwords for all email accounts? (because, of course these may have been written down years ago but cannot be located at this time. :-( ) Or, is there some way of restoring the email account passwords?

• • • side note: The migration was not seamless but mostly due to my own ignorance. When using the export/import tool from one Linux machine to another I found the following:

- Thunderbird versions must be the same on both computers - After export, file on USB drive was only accessible by root on new computer - export zip file needed to be copied to user account on new computer (from within root account) and ownership changed to [user]: -R (I imagine you could just change ownership on the USB but this seemed easier)

This morning, I repeatedly received an "Authentication failed when connecting to outlook.office365.com" error. I removed the Outlook account from Thunderbird hoping to solve this by reconnecting and starting from scratch. Upon entering my email and password, my configuration is successfully located in the Mozilla database, but upon selecting the IMAP configuration and after a brief password check, I received the error message "Unable to log in at server. Probably wrong configuration, username or password". Is this an issue on Outlook's end, or is something not set up properly?

My Hotmail account suddenly stopped working today (was working yesterday). Thunderbird shows a popup saying authentication failed, but doesn't ask me to try a different password (not that I changed it recently).

The error details are only visible in Error Console:

Got an error name=oAuth2Error, the server said: Authentication failure: unknown user name or bad password.

Using server: outlook.office365.com, port 995 (POP) user name: ****@hotmail.com SSL/TLS, OAuth2

I can't log in after changing my email password. My email address is [edited]@telia.com. I can log in with my new password using Telia Webmail. I have been in contact with Telia and they refer you. Best regards Anita Bodin

I've read everything apropos here, tried everything, and I'm lost--and totally screwed--if I can't get into my old Thunderbird. Spectrum, computer died, nobody competent here to get past "Registry Error," I guess, but I need all the data, contacts, calendar, etc., in the T'bird I've relied on for MANY years. PLEASE help. I tried to get a screen grab: It didn't work.

This is the second time I've appealed for help.

I can't sign in to my email ([edited] @yahoo.com) on my desktop running Windows 11 Pro. I have changed password which has been confirmed with still no joy. I get the message:-If you still can't sign in try a different device. My wife can sign in on her Android phone but I can't

Hi,

I'm using a google provided email (but it's not gmail) which is provided by my school. When I try to set up my email, everything works fine, Thunderbird detects the settings. When I try to log in I get the error message "Unable to log in at server. Probably wrong configuration, username or password". If I go though the settings the authentication method is "normal password" when it should be "oauth2" but that option is missing. The pop-up to log in to my Google Account to authorize the app does NOT appear no matter what.

I've had this issue multiple times in the past (as I change schools) and I was able to solve it once. In my Windows install I changed some flag in the Config Editor (and I forgot which) and the following time I tried to add the account the Google authentication pop up appeared. Do note that the outlook app (new one and classic) sets up the account just fine without me having to configure or change anything.

So right now I have Thunderbird able to access that account on Windows, but I can't get my install in Nobara (Fedora based) to do so because (I think) the Google authentication pop up doesn't open so that I can go to the account and allow the specific Thunderbird install to use the email.

I've also tried 4 or 5 other email clients available in Flatpost and none are able to trigger the Google pop up thing. I don't think the issue is the OS because I had the same exact issue with thunderbird on Windows until I changed some flag in the Config Editor.

I would appreciate if anyone could help me out, i've spent hours scouring the internet for options and (unfortunately) nothing has worked so far and I've been unable to find the instruction with the flag I need to follow that fixed my issue the other time.

Hello, ​I am reaching out to request assistance in recovering access to the following email address: <redacted>@football-sapeurs-pompiers.fr. ​Following the theft of my laptop, which had an automatic login enabled, I am no longer able to access this account. Unfortunately, I do not have the password saved, and no one within the association is able to provide it. ​The standard "forgot password" procedure is currently not working for me. Could you please advise on how I can reset the password so that I can set up this email inbox on my new computer? ​I am available to provide any necessary identification or proof of my role within the association to facilitate this request. ​Thank you in advance for your help. ​Best regards,
