HTTP request
POST /me/sendMail
POST /users/{id | userPrincipalName}/sendMail
Indicates whether to save the message in Sent Items. Specify it only if the parameter is false; default is true. Optional.
When specifying the body in MIME format, provide the MIME content as a base64-encoded string in the request body.
Response
If successful, this method returns 202 Accepted response code. It doesn't return anything in the response body.
Note: A 202 Accepted response code indicates that the request has been accepted; however, it does not indicate that the request processing has completed. Delivery of the message is subject to Exchange Online limitations and throttling.
If the request body includes malformed MIME content, this method returns 400 Bad request and the following error message: "Invalid base64 string for MIME content."
