@pkometineni,
Starting with upcoming version 21.10, optional attendees will be displayed in output MHTML for MhtFormatOptions.WriteHeader | MhtFormatOptions.RenderCalendarEvent options.

Also, you will be able to disable them in the following way:

// MhtSaveOptions 
options.FormatTemplates[MhtTemplateName.OptionalAttendees] = "";
