(Swift 2) Outlook Calendar OAuth2 Access Token - Using Azure AD v2.0 EndpointSee more Outlook Calendar ExamplesDemonstrates how to get a Microsoft Graph OAuth2 access token from a desktop application or script using scopes for Outlook Calendar. Microsoft Graph supports two authentication providers:
This example uses the Azure Active Directory (Azure AD) v2.0 endpoint. For more information, see https://docs.microsoft.com/en-us/graph/api/resources/calendar?view=graph-rest-1.0
