Are free Office accounts supported by Azure AD?
I've tried authenticating with two different accounts, one that has a monthly Office 365 Family subscription, and another free account I created.
I also have set up Microsoft sample users, and these are all working fine. But whenever I try to log into Outlook or OneDrive from my integration with either of the two accounts I mentioned above, authentication fails.
I can't find anything in the documentation that explains which types of accounts are not supported.
The Auth Code received for the Family and Free accounts look like this: M.R3_BAY.c531716c-c315-0c1e-7113-8805ab255856, which is obviously wrong.
I also asked this question in StackOverflow with no luck. This is the link: https://stackoverflow.com/questions/65056867/invalid-grant-error-for-free-office-accounts
Any help will be greatly appreciated.
