Outlook Contact OAuth2 Access Token - Using Azure AD v2.0 Endpoint

See more Outlook Contact Examples

Demonstrates how to get a Microsoft Graph OAuth2 access token from a desktop application or script using scopes for Outlook Contact.

Microsoft Graph supports two authentication providers:

• To authenticate users with personal Microsoft accounts, such as live.com or outlook.com accounts, use the Azure Active Directory (Azure AD) v2.0 endpoint.
• To authenticate users with enterprise (that is, work or school) accounts, use Azure AD.

This example uses the Azure Active Directory (Azure AD) v2.0 endpoint.
