I'm trying to using rclone with my OneDrive Business account. The default client ID works, but my own client ID (created according to the doc) didn't work.
Eventually I managed to make it work. Basically the idea is to create a single-tenant App (i.e. organization only).
Currently the doc describes the steps to create a multi-tenant App, which may not work for some (or many?) OneDrive Business organizations. See the purple box in this doc.
