Get original message headers using EWS for bounced emails

Question

I have done some research and also some code testing with Microsoft Exchange Server 2010 to realise that in bounced e-mails, the headers are being removed. One of the articles I referred to was this: Detecting bounced messages by return-path header.

The problem I have is trying retrieve custom headers from bounced e-mail, but it seems impossible according to my research. The other solution that was mentioned in the above article was using the return-path address.

However, when I access my web e-mail using Microsoft Outlook Web App, and checking the e-mail that was bounced back to my address, I was able to view the original message headers. So, is it possible to use EWS managed API to retrieve the original message headers?

The original message header is follows:

Diagnostic information for administrators:

    Generating server: MXG001.domain.com

    email.that.do.not.exist.1234567890@gmail.com
    gmail-smtp-in.l.google.com # #SMTP#

    Original message headers:

    Return-Path: sender@domain.com
    Received: from MXG001.domain.com (unknown [127.0.0.1]) by IMSVA (Postfix)
     with ESMTP id 1484C26805C  for ;

I use the code below to write a client to access EWS which works fine as well. So my only problem is if it is possible to retrieve the original message header? If so, how can I do it? Thanks!

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
service.Credentials = new WebCredentials(@"myUsername", "myPassword");
service.Url = new Uri("https://webmail.domain.com/ews/exchange.asmx");

Folder inbox = Folder.Bind(service, WellKnownFolderName.Inbox);
SearchFilter sf = new SearchFilter.IsEqualTo(ItemSchema.ItemClass, "REPORT.IPM.Note.NDR");
SearchFilter searchFilter = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter[] { sf });
ItemView view = new ItemView(20);

FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, searchFilter, view);

foreach (EmailMessage item in findResults)
{
// Can process whatever is necessary here                  
}

Managed to solve it. I can retrieve the original message headers which are actually stored as ItemAttachment in the bounced e-mail. — sendoh07, Aug 30 '12 at 01:48

In 2022, To me it seems you are missing this line to load Message headers. EWS being a lightweight service it doesn't load all the info(like body/header) so you need load it with the below line.

item.Load(new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.InternetMessageHeaders));

so that it looks something like this:

foreach (EmailMessage item in findResults)
{
    item.Load(new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.InternetMessageHeaders));
    //Then item.InternetMessageHeaders will be populated
     Console.WriteLine(item.InternetMessageHeaders);     
}
