Get original message with headers when forwarding message before sending in EWS

Question

I'm trying to provide a way to forward emails, just as we do in Outlook. When the user clicks forward, it opens a form with the original message and header information on top, giving the user an opportunity to modify the body. To get the message, I do the following.

    var item = (EmailMessage)dataGridEmail.SelectedItem;
    ResponseMessage forward = item.CreateForward();
    textBlockForward.Text = forward.Body;

I get an ServiceObjectPropertyException with message "You must load or assign this property before you can read its value". If I try to load the value of the body property before accessing, I get NotSupportedException with message "Specified method is not supported". Is there a way to get the forwarding message before actually sending it?

Answer 1

Instead of using forward.Body, you should use item.Body to populate your textBlockForward control. See Forwarding Email Messages using EWS on MSDN for more details.

var item = (EmailMessage)dataGridEmail.SelectedItem;
ResponseMessage forward = item.CreateForward();
textBlockForward.Text = item.Body; // needs to come from original message source
forward.BodyPrefix = "new body contents"; // prepended body content

I am note sure if anyone could solve this. This is what i did.

    ResponseMessage responseMessage = message.createForward(); 
    // message is an EmailMessage object
    responseMessage.setBodyPrefix(body);
    responseMessage.save(WellKnownFolderName.Drafts);
    EmailMessage saved = responseMessage.save();
    saved.load(new 
    PropertySet(BasePropertySet.FirstClassProperties,ItemSchema.Body));
    MessageBody messageBody = saved.getBody();
    // do something with messageBody`enter code here`
    //System.out.println(saved.getBody().toString());
    saved.sendAndSaveCopy();
