Hi,
I can create an email using MailMessage and add a Customer Header to it, I can then have SmtpClient send this email so that when I read the email again using the ExchangeClient FetchMessage Class I can reread that same header again, this appears to work fine.
However, if in the first instance I create an email then save as DRAFT status using MapiMessage.SetMessageFlags(MapiMessageFlags.MSGFLAG_UNSENT) and then save this email to file as a .MSG file, reopen and send, I can see the email in my inbox and if I use Outlook to view the headers I can see my custom headers, but this customer header is missing if I read the email using ExchangeClient.FetchMessage?
My question is, how do I go about reading these custom headers that I can view with regular outlook when the email was generated as a Draft and sent manually?
