OAuth2 is REQUIRED now for MS Outlook email, now I get prompts for passwords

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

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 run Thunderbird 102.13.0 (32 bit) on W10 Home. After Thunderbird updated late last week I have been having problems sending emails with my work Microsoft Outlook Office365 account (no such problems up to last Thursday 13 July) : Emails with just a couple of words in the body arrive but with nothing in the body. Emails with just a couple of words in the body and a text file attached arrive but with nothing in the body and without the attachment. Emails with just a couple of words in the body and a Excel file attached fail to send at all (error message). No such problems sending emails via the Office 365 web portal. I have Exquilla installed and its licence is current. Tried removing the Outlook account and re-installing it, but this made no difference. Temporarily disabling my ESET NOD32 AV software made no difference either. Tearing my hair out. Would anyone have any ideas on how to fix this ?
