API Reference and Permissions
Let see the following Docs for more Details.
So we need the following Application/Delegated Permission for our Azure App Registration.

The Script
$clientID = "your Client ID"
$Clientsecret = "Your Secret"
$tenantID = "your Tenant"
$UPN = "first.last@techguy.at"
$HTMLintern=@"
<html>\n<body>\n<p>I'm at our company's worldwide reunion and will respond to your message as soon as I return.<br>\n</p></body>\n</html>\n
"@
$HTMLextern=@"
<html>\n<body>\n<p>I'm at the Contoso worldwide reunion and will respond to your message as soon as I return.<br>\n</p></body>\n</html>\n
