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(M ailMessage Mail, MailItem item)
{
string path "Messages\\mess age" + message_id+ ".MSG";
Mail.IsBodyHtml = true;
item.SaveAs(pat h,
Microsoft.Offic e.Interop.Outlo ok.OlSaveAsType .olMSG);
System.Net.Mail .Attachment attach = new
System.Net.Mail .Attachment(pat h);
attach.Name = "OriginalMessag e.MSG";
Mail.Attachment s.Add(attach);
message_id++;
}
