    // See Global Unlock Sample for sample code.

    // Use your previously obtained access token here:
    // 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).
    //    Refresh Access Token (Azure AD Endpoint).

    // To send email, we'll POST to the following endpoint:
    // 
    // POST /users/{id | userPrincipalName}/sendMail
    // 
    // (The special keyword "me" may be used in place of a principal name.)
    // 

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