        Create a draft to forward an existing message, in either JSON or MIME format. When using JSON format, you can:- Specify either a comment or the body property of the message parameter. Specifying both will return an HTTP 400 Bad Request error.- Specify either the toRecipients parameter or the toRecipients property of the message parameter. Specifying both or specifying neither will return an HTTP 400 Bad Request error.- Update the draft later to add 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, forward a message in a single operation.
