'  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:
