I-Thunderbird Community Forum

Hi all! I'm having an issue with Thunderbird in conjunction with my Outlook account.

I used to be able to add my account just fine (using OAuth2). But for a few months now, I have been getting "Authentication failed" errors (see first picture).

It used to be that I could temporarily remedy this by signing out and back in. Today, however, I was unable to sign back in, using the stock settings for Outlook (see second - fourth picture). No authentication popup appeared.

I was sporadically able to add the account and get messages to start appearing by clicking on "Edit configuration" and removing and re-adding the hostname for the IMAP server, without an authentication popup appearing. I therefore suspected that there might be some half-stale credentials stuck in the cache, and there probably were, because after clearing my cache this method doesn't work anymore. I am still not getting any authentication popup though.

All the usual suspects I already tried: Thunderbird is up-to-date (151.0.1), my Outlook account definitely has IMAP and SMTP activated, and another mail account (gmail) works without a hitch on the same system.

I hope that someone can help me, as I'm at my wit's end. Thanks in advance!

Xfinity email service required me to change my password (security issue?). I went through the process but when I attempted to change my password in TB, it required me to change both the imap and smtp servers separately.

Apparently this is normal for TB. But this is radically different from other email systems. Most allow me to change the password once and it propagates to both the imap and smtp servers.

Am I missing something. If not, why does TB do it this way? This is extremely frustrating and unexpected for many people, I would think.

Oh, this is especially frustrating because I'm in a situation where two of my three Xfinity email accounts are repeatedly requiring a password change. I'm still trying to get to the bottom of that with Comcast.

Since Friday I have not been able to use thunderbird. I can open it but it wont connect to Virgin.com I have checked all settings (click on test connection it states good) then every five minutes when it try's to connect I get the following message (email address removed)

Login to server pop3.virginmedia.com with username ******* failed

I still get mail on my phone so it's down to a Thunderbird issue I believe. Tried to reinstall same issue, tried a new account and wont allow me to authenticate.

PLEASE can someone help - have a load of work to do but can't get on. Thanks in advance David.

Thunderbird for NixOS nixos - 1.0

I could not figure out how to provide a log at all. If there is a way, please let me know and I will provide one.

Whenever I try to log in with gmail, I get stuck on this dead end:

1. Set up gmail server config (because my email ends in @vcu.edu, however I have tested this with a proper @gmail.com email and observed the exact same behavior)
2. Get propted to login with google, which works
3. Get to the "Mozilla Thunderbird Email wants access to your Google Account" page, select all and hit continue
4. get redirected to `http://localhost:35141/?state=<string of chars>&iss=https://accounts.google.com&code=<another string of chars>&scope=https://mail.google.com/%20https://www.googleapis.com/auth/carddav%20https://www.googleapis.com/auth/calendar` This page does not load, I just get a "unable to connect" error
5. get a notification stating "Authentication failure while connecting to server `imap.gmail.com`
6. get ANOTHER prompt to log in with google, exact same thing happens

please note that the port is random and is different every single time. also, google does not register that I have allowed Thunderbird access to my account, and it prompts me again every single time.

I believe this is all the information i can provide. Firewall was disabled for testing. I cannot log into either my school or personal gmail accounts.

I cannot sign in. My login information is 100% correct. I just created the email a week or so ago so I assume i have the latest version. I signed in a few days ago with no issue. I tried clearing cache. Not sure where to go from here.

Having established a new Outlook account I cannot sign into it properly with Thunderbird - I get authentication failures each time despite all settings apparently being correct, IMAP enabled in the web browser view of the outlook account and so on. Oauth2 set and all server settings good. I have been over and over things. Tried various suggestions of the web to no avail.

I have tried unsuccessfully with three separate machines - two Microsoft 11 laptops and an iMac. All fail.

I can access the account and send/receive emails from a web browser and I have got it working okay with an iPhone, an Android tablet and a Microsoft email client - but not with Thunderbird. I even get a browser popup on the iMac when I open Thunderbird asking if I am trying to sign in - I say yes and it says I am all signed in - but the email doesn't authenticate. I have passcodes all set up etc.

A separate Hotmail account does work with the same Thunderbird client and has the same server settings (apart from the username obviously).

I am at a loss how to resolve this other than move to a different email application.

Any ideas?

I keep getting the sign in request (photo 1) and when I click the next button I get (photo 2), I have no idea what has changed or what I can do to stop it. I would be grateful of any help.

Yesterday I changed my AOL password online. Now Thunderbird email no longer works. I get a popup labelled "enter credentials for user on pop.aol.com". Within the popup window it says "Edge: Too Many Requests"

Settings have not changed and worked prior to password change. I believe if the popup window was working correctly I could enter my new password and all would be fine.

pop.aol.com 995 SSL/TLS OAuth2

smtp.aol.com 465 SSL/TLS OAuth2

Thanks,

Ed

I cannot login to Thunderbird. I have a Telstra Bigpond email account. I have set it up for imap using the Telstra settings. My password is correct but it is not accepted and I cannot login.

Hallo, ich habe bei meiner derzeitigen E-Mail-Adresse: <redacted>@tmo.at das Passwort nicht mehr. Zur Verifizierung könnten meine anderen E-Mail-Adressen: <redacted>@gmail.com oder <redacted>@gmail.com verwendet werden.

Mit freundlichen Grüßen

Have installed Thunderbird on an IMAC computer. From day one Thunderbird has been slow to open. Message box appears asking me to enter Login password. Sometimes doesn't accept password. Have to retype password again.

Without warning, password rejected. My internet provider, Uniserve, gave me a temporary password for Thunderbird. Created a new password for Uniserve Webmail and Thunderbird. Worked for a while. No problem receiving and sending e-mails.

This morning my new Thunderbird password is being rejected.

What could be the problem?

I have not been able to open emails in Thunderbird since 9:30 yesterday morning. Nothing has been changed in the settings. It randomly started asking for the password. When I enter the password (which is working for mail.yahoo), I receive the following message:

Login to server pop.att.yahoo.com with username XXXX@att.net failed.

I've tried the 'retry' button and 'enter new password' many times without success. I'm using Windows 10 and Thunderbird 140.1.0esr.

I'm self-employed and desperately need access to Thunderbird. This has happened many times over the years, where it randomly stops working, then mysteriously fixes it on it's own. Any guidance would be greatly appreciated.

Thank you for your help.

I have tried all combinations of email addresses and passwords to get access to the list of my passwords in Thunderbird. I am asked to give my username for "enhetsinloggning" (swedish). But none of my emailadresses works. What can I do? Luckeky I know all my passwords but I still want the list. /EvaK

When setting up TB to use my Gmail, I can successfully set up the configuration, but when I "allow" TB to access my Google account, the credential process starts, but never complete. Note that sometimes I get a security alert indicating the TB has been granted access to my google account, but TB is not actually updated

Bonjour

Dans Thunderbird ordinateur Première utilisation / Configurez votre adresse mail existante /

après avoir rempli "Nom complet" puis "Adresse mail" puis "Mot de passe" et sélectionné "IMAP"

message d'erreur suivant: " Connexion au serveur impossible. La configuration, l'identifiant ou le mot de passe sont incorrectes".

Est-ce que cela proviendrait du fait que l'adresse mail est configurée avec un deuxième facteur (2FAS) ?

Si oui, comment procéder ? Toutes mes adresses mails sont paramétrées avec un deuxième facteur d'authentification (2FAS).

After many years of using Thunderbird I am now considering ditching it. I am continually getting the Authorisation Failure message when trying to open Thunderbird. Why does this keep happening? It does not happen on my Android devices, just on Windows 11. I have tried deleting all three gmail accounts and re entering them. All is fine until I close down Thunderbird and then open it again. I run Norton 360 and have tried taking off Norton email security, but that didn't work. Any ideas, please?
