Question

    var message = EmailMessage.Bind(exchangeService, itemid,
                                       new PropertySet(
                                                       ItemSchema.Attachments));




    exchangeService.TraceListener=new TraceListener();
    exchangeService.TraceEnabled = true;
    message.Load(new PropertySet(ItemSchema.MimeContent)); // Getting exception here.
   //  File.WriteAllBytes("email.eml", message.MimeContent.Content);

我在尝试加载mime内容时遇到以下异常。
