I can access the email account fine using the O365 python module, but if I extract the access token from the FileSystemTokenBackend file for use with fetchmail, I get an authentication error. I've also verified that the extracted access token is good using Microsoft's tool (https://jwt.ms/). Here are my specifics (per the FAQ G3):

David, how long is the "password" token?

ls -l /opt/rt-oauth/fet...@wi...cess

I have recently released fetchmail 7.0.0-alpha8 with an increased maximum password length of 10,000 bytes net, but the announcement hasn't made it through to the list yet, for reasons unknown (no bounce received yet), hence I am Cc:ing you (out of the ordinary).
