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

$oHttp = ObjCreate("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).

$oHttp.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>
;  	</font>
;  	</body>
;  	</html>

;  Build the HTML body...

$oSbHtmlBody.AppendLine("</html>",$bCrlf)

;  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:
