My email account is handled by a university that uses Office 365-based Microsoft system for email accounts. My institution now requires that email client programs us MS Graph for authentication. Does Thunderbird 156.0.1 have this capability?

I was having trouble with Thunderbird outgoing mail. I changed some settings and it still didn't work. I tried to log in to Thunderbird and now cannot log in at all. I have 25 years worth of email in this account!

Repeated attempts to log in using the window presented continue to fail. My password is correct and I am able to log in on the spectrum website without problems. I have two email accounts in TB ; one with Outlook.com and the other with Charter.net. The Outlook account logs in without problem but the charter account continues to give me the message that the login failed (image attached). When I go too the account server settings in TB for charter and do a test connection under security settings, a connection is made without a problem (image attached).

I believe the previous version (156.0) was working but there seems to be a rapid succession of changes coming down the pike lately. I have had intermittent problems of this nature in the past 4 or 5 months so it's difficult to keep track of which versions are successful.

Help please. I am not thrilled with spectrum but I do not want to change my email address.

Hello,

There is apparently a bug in the latest release of Thunderbird, which has broken the callbacks for Yahoo! IMAP email using OAuth. Potentially, it may actually be a problem with Yahoo!, and how https://api.login.yahoo.com is attempting to reopen Thunderbird after logging in, as the process has changed. I've already reverted back to the ESR Thunderbird channel once, but on a recent update the issue was reintroduced. Screenshots are included.

Thanks for any assistance.

Hello. i have latest beta 156.b3 64bit, after updating to beta 3 my tb offer retry passwords to many google acccounts and opening FireFox for again login in to each account. I have turned off checking mails on the start up for them and turn off checking mails, but again and again opening firefox for signing in. i closing firefox but TB not continue checking mail from another mailboxes, they stopped and seems like waiting for signing. i try to manually click for each mailbox "get message", but this no work, could you help me turn off login through firefox?

I downloaded Thunderbird on my new Windows 11 laptop and began setup by entering my full name and email address ([redacted]@utexas.edu, operated by Gmail). The next screen asks for my "email account password." I entered my Google password that allows me to access my email at Gmail (https://mail.google.com/mail/u/0/#inbox). But "Authentication failed," and I am stuck! I cannot finish installing Thunderbird. I have used Thunderbird for many years on my prior laptop (Windows 10).

I have an outlook account that will not install. I get the challenge, to send me an authentication number at another email address, and that says okay, you can close this window and continue, but then at 'continue' in Thunderbird I get an authentication error.

-I have added the email on another computer in Thunderbird and send/receive email, no error -I have added the email in the New Outlook email app and send/receive email, no error -I have added a different outlook account in Thunderbird on this computer, no error -I can log into the Microsoft live email app and send/receive email, no error -I have uninstalled Thunderbird as admin, removed the Thunderbird folders in %appdata% and %localappdata% for both the admin and user accounts, cleared the cache and cookies on the computer and in Thunderbird (including the token), then reinstalled Thunderbird under the admin account, logged into Thunderbird as the user and added the problem Outlook account; same issue. Press Continue and authentication error, even though the challenge screen says everything is connected and okay. Then I install the other Outlook account without any issues.

I am convinced that somewhere on this machine there is something that knows and hates this one email account. It is possibly because the profile file had a problem and I deleted the xulstore.json file per instructions to resolve the problem, but the file is there and the profile is working again for the other Outlook accounts, just not this one particular account.

Any Obi-wan or other wise counsel out there?

For the past 3-4 days, I am unable to successfully add my Yahoo New Mail account to Thunderbird.

The app says it cannot authenticate my account, but Yahoo confirms Thunderbird's access.

I'm using Thunderbird Version 155.0.1 (64-bit). I reinstalled it after cleaning the installation of Windows 11 25H2 a few days ago.

Please help. I need to move all my Gmail messages to Yahoo, and Thunderbird is the only option I have.

Thank you in advance!

Hello forum,

I have 2 mail addresses at gmx.de. I can’t sign up for either of them for a few days. I get the note: password wrong. I use the same password for both email addresses. I can sign in to both addresses via the browser at GMX, but not in the Thunderbird that I have been using for years. I have always called the two e-mail addresses via Thunderbird. I can't explain a reason for this problem. I hope that's from any of you.

Greetings Dieter

Hallo Forum,

ich habe 2 Mail Adressen bei gmx.de. Bei einer von beiden kann ich mich seit ein paar tagen nicht mehr anmelden. Ich bekomme den Hinweis: Passwort falsch. Ich verwende bei beiden Mail Adressen das gleiche Passwort. Ich kann mich über den Browser bei GMX bei beiden Adressen anmelden, aber nicht im Thunderbird, den ich seit Jahren benutze. Auch die beiden Mailadressen rufe ich schon immer über Thunderbird ab. Ich kann mir keinen Grund für dieses Problem erklären. Hoffentlich kann das jemend von Euch.

Grüße Dieter

My office has moved our emails onto a microsoft exchange server. I backed up my emails, removed all accounts, settings, passwords and then rebooted. Found instructions online. Went to add account > New mail. The account hub page after selecting "new mail" asks me for my name and email. after I input that, it then allows me to continue. It says "account settings found automatically" and offers me 3 options - IMAP, Exchange or Exchange (with owl add on). I select Exchange. In the left hand box next to the options, It shows all the email details and then at the end "authorisation by normal password". I try to click "edit configuration" but nothing happens, so I select "continue". The page now asks for a password. I input the password the IT shop guy gave us and then press continue but get an error message at the top - "unable to log in at server. probably wrong configuration, username or password". The only inputs available to me are the password line and the "back" or "continue" buttons. No trigger of my web browser occurs in order to input any Authorisation on microsoft via my Authenticator app.

What can I do (besides using OWL - I don't have the spare funds for yearly subscription)?

Thanks
