First, I launched all steps " Getting your own Client ID and Key"
Then, I run
rclone config
In step redirecting to http://localhost:53682/ I got an error.
Signing to Microsoft failed with "You can't sign in here with a personal account. Use your work or school account instead."
Choose a number from below, or type in an existing value
1 / OneDrive Personal or Business
\ "onedrive"
2 / Sharepoint site
\ "sharepoint"
3 / Type in driveID
\ "driveid"
4 / Type in SiteID
\ "siteid"
5 / Search a Sharepoint site
\ "search"
Remote config
Make sure your Redirect URL is set to "http://localhost:53682/" in your custom config.
Use auto config?
Say Y if not sure
Say N if you are working on a remote or headless machine
y) Yes
n) No
y/n> y
If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth
Log in and authorize rclone for access
Waiting for code...
And on Microsoft site I got auth error "You can't sign in here with a personal account. Use your work or school account instead."
I am also experiencing this problem, except I actually did use Any Azure AD directory - Multitenant not Any Azure AD directory - Multitenant and Personal
