Oauth2.0 on microsoft.com

K-9 Mail Version 6.202

I have an email account on Office 365 which is requiring me to convert to Oauth2.0 authorization. My email address is user@alumni.caltech.edu and my login name to the outlook office365 server is user@alumni.caltech.onmicrosoft.com.

This works for the normal password. When I select Oauth2.0 as my authentication a pop-up appears requesting my password. However, the pop-up fills in my username as my email address and not the Office 365 username user@alumni.caltech.onmicrosoft.com. That field cannot be changed and I am unable to complete the update to use Oauth2.0 as my authentication.

Thanks for any help you can give me.
