Attach An outlook message to an outlook message

[mmatchyn]

How do I attach an outlook email message as an attachment within
another outlook email message.

Right now I am using the following code. But I was wondering if there
is a better way to do this without using a file that needs to be
deleted later.

private MailMessage addAttachment(MailMessage Mail, MailItem item)
{
string path "Messages\\message" + message_id+ ".MSG";
Mail.IsBodyHtml = true;
item.SaveAs(path,
Microsoft.Office.Interop.Outlook.OlSaveAsType.olMS G);
System.Net.Mail.Attachment attach = new
System.Net.Mail.Attachment(path);
attach.Name = "OriginalMessage.MSG";
Mail.Attachments.Add(attach);
message_id++;
}
