From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

Hello,

I am using the latest stable release of Thunderbird client on Windows 11 and just today it's been asking me multiple times for a password to my Outlook account. I have kept adding a one time app password through the official Microsoft website under account management but it's been asking a few times that it needs a password.

Do you know if there's been any outages to the Microsoft servers or what this issue could be related to? Is there a way I can send any logs directly to you that might help find the issue?

Thank you for your time.

Right then, about a week ago Thunderbird updated from 115.2.2 to 115.2.3.

I use TB to manage my Gmail, Hotmail and business emails. Has worked well, until this new update.

I began immediately receiving a pop-up regarding my Hotmail account. Sometimes the pop-up flashes for a few seconds, other times it stays on the screen.

https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=XXXX%40hotmail.com

• The XXXX is my email name removed.

The pop-up is mostly blank except for a text box at the very top with a long string of characters. Above that it states, 'Enter credentials for XXXX@hotmail.com at Outlook.Office365.com'. I can't figure out if it wants me to enter the string of characters somewhere on Outlook or if I am supposed to copy something from Outlook and paste it into the text box. Moreover, I cannot seem to find anything online to assist.

The problem is emails from Outlook are not downloading to TB. My last downloaded email was on 11.09.23 and there are new messages in my Outlook.

Ideas?

I was able to send emails till July 14. After that day it's been impossible to send or reply to messages from my Outlook account (I receive emails though). I have made no changes to Thunderbird's configuration since then. Basically it's the Oauth2 authentication that fails. I briefly see a browser page for authentication, wait, wait, wait and then the mail is not sent and I get an error message related to servers timeout (attached). Sorry, my interface is in Italian, but anyway the message is something like: "Unable to send email because of a timeout on the connection to the out server (SMTP) smtp.office365.com. Try again." Is this a known bug? Any ideas? It's quite annoying to use the browser interface to send messages while I am able to receive them in Thunderbird :) Thank you in advance, guys!

Hello,

an update to Thunderbird 115.0.1 prevents e-mail sending from one account, although incoming items are displayed. A new password option fails. However, Outlook e-mail account runs as usual with expected password and sends as expected.

We have set an IMAP protocol and as this arose, changed authentication method from 0Auth2 to normal password, as yet with no effect. Any pointers to reactivate our e-mail sending shall be appreciated.

With kind regards,

                                Colin.
