Just want to report back that after confirming with an MS representative
through online chat, outlook.com has actually disabled refreshing
access_token through the token endpoint, and users are asked to migrate
to Outlook app or compatibles apps (Thunderbird still works).  I'm not
sure whether this is also the case for organization emails, which may
also be disabled by default (or soonish if not already) but can be
enabled separately by an org admin.  Anyway, I'd suggest people stop
wasting your time here and use Gmail (or maybe Yahoo mail) which has
decent 3rd party OAuth2 support.

Meanwhile I have submitted a request to re-enable this support[1].
