‘Unable to retrieve user’s mysite URL.’ Using Client Credentials One Drive is this because I’m using 365 family? not 365 business ? { “error”: { “code”: “UnknownError”, “message”: “Unable to retrieve user’s mysite URL.”, “innerError”: { “date”: “2022-03-17T17:08:21”, “request-id”: “a6717666-1188-4e65-af8f-61e14e419d82”, “client-request-id”: “a6717666-1188-4e65-af8f-61e14e419d82” } } } Answer I have checked and confirmed with azure, that only Microsoft Business Plan is allowed
