Note: The default MSG is to get the text message content to get the HTML content code as follows

var dataStream = Msg. Alternateviews[0]. Contentstream;
byte[] Bytebuffer = new Byte[datastream.length];
String altbody = Msg. Bodyencoding.getstring (bytebuffer, 0, Datastream.read (bytebuffer, 0, bytebuffer.length));
