Hi @australian.dev.nerds

You code is mistaken, please try code below and compare results.

            MailMessage msg = Appointment.Load(fileName).ToMailMessage();
            msg.Save(fileName + ".mhtml");//saved as eml by default
            MhtSaveOptions opt = SaveOptions.DefaultMhtml;
            opt.MhtFormatOptions = opt.MhtFormatOptions | MhtFormatOptions.RenderCalendarEvent;
            msg.Save(fileName + "_cal.mhtml", opt);//saved as MHTML with CalendarEvent fields and body
