        Create a draft to reply to the sender of a message in either JSON or MIME format. When using JSON format:- Specify either a comment or the body property of the message parameter. Specifying both will return an HTTP 400 Bad Request error.- If replyTo is specified in the original message, per Internet Message Format (RFC 2822), you should send the reply to the recipients in replyTo, and not the recipients in from.- You can update the draft later to add reply content to the body or change other message properties. When using MIME format:- Provide the applicable Internet message headers and the MIME content, all encoded in base64 format in the request body.- Add any attachments and S/MIME properties to the MIME content. Send the draft message in a subsequent operation. Alternatively, reply to a message in a single operation.
