    //  See Global Unlock Sample for sample code.

    //  See the following examples for getting an access token:
    //     Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
    //     Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
    //     Refresh Access Token (Azure AD v2.0 Endpoint).

    //  To send email, we'll POST to the following endpoint:

    //  POST /users/{id | userPrincipalName}/sendMail

    //  

    //  The body of the POST request contains JSON that specifies the email subject, body,
    //  recipients, etc.  This example will build the following JSON email:
