I can manage sharing access by user to his personal Office365 account via OAuth2. This article does not contain information how to revoke the access. I believe there is should be REST API to revoke shared access.
Can I have help or missed link to Office365 developers API where I could find correspond documentation please?
If you want to revoke access token issued by azure ad , currently , Azure AD doesn’t support revoking the token . However, we can clear the token cache if you doesn’t want users to user the token. You could also read document Configurable token lifetimes in Azure Active Directory to specify the lifetime of a token issued by Azure Active Directory (Azure AD) .
