Thanks! I was looking around git and I guess the python code to get the token file is perhaps here: https://sourceforge.net/p/fetchmail/git/ci/next/tree/contrib/fetchmail-oauth2.py#l140
But then, I was wondering where is the code in fetchmail that makes it work (i.e. makes use of the oauth2 written in the rc file):

    poll imap.gmail.com protocol imap
      auth oauthbearer username "US...@gm..."
      passwordfile "/home/path/to/access_token_file"
      is LOCALUSER here sslmode wrapped sslcertck

This is for gmail, mine is for office 365 so I am wondering if there are areas in the main source code that I have to modify. (I have the python code needed to get the token.) It seems to me that fetchmail has to recognize and make use of the oauthbearer hence my question.

Many thanks,
Ranjan
