' Important: This example requires Chilkat v9.5.0.68 or greater.

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http")
set http = CreateObject("Chilkat.Http")

' 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).

http.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

' To send mail, 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.)
' 

' This example will send HTML email containing the following HTML body:

' 	<html>
' 	<head>
' 	<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
' 	<meta content="text/html; charset=utf-8">
' 	</head>
' 	<body bgcolor="#FFFFFF">
' 	<font face="Calibri">This is a test <b>HTML email</b>.<br>

' Build the HTML body...

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