Create an email using EWS Exchange and attach another email

问题

I'm having trouble attaching an email to a new email using EWS.

So i have the Microsoft.Exchnage.Webservice.Data.Item in my findResults.

If I find an issue in the form data of the email then I want to attach that item to a new email and send it to a supervisor for manual input.

I have tried;

EmailMessage newMessage = new EmailMessage(exchange);
newMessage.Subject = "Failed lead creation";
ItemAttachment attachment = new ItemAttachment("New Lead", message);

I can't seem to create the ItemAttachment as the erro I am getting is "ItemAttachment does not contain a constructor that takes 2 arguments".

How do I create a new message in EWS, attach the current Item to it and send to another recipient?

You can't another message directly you need to use the MimeContent of the Original Message and then create an ItemAttachment based on that eg something like

    FolderId  folderid= new FolderId(WellKnownFolderName.Inbox,"MailboxName");    
    Folder Inbox = Folder.Bind(service,folderid);  
    ItemView ivItemView =  new ItemView(1) ;     
    FindItemsResults<Item> fiItems = service.FindItems(Inbox.Id,ivItemView);
    if(fiItems.Items.Count == 1){  
    EmailMessage mail = new EmailMessage(service);   
    EmailMessage OriginalEmail = (EmailMessage)fiItems.Items[0];
    PropertySet  psPropset= new PropertySet(BasePropertySet.IdOnly);    
    psPropset.Add(ItemSchema.MimeContent);
    psPropset.Add(ItemSchema.Subject);
    OriginalEmail.Load(psPropset);  
    ItemAttachment Attachment = mail.Attachments.AddItemAttachment<EmailMessage>();
    Attachment.Item.MimeContent = OriginalEmail.MimeContent;  
    ExtendedPropertyDefinition PR_Flags = new ExtendedPropertyDefinition(3591, MapiPropertyType.Integer);    
    Attachment.Item.SetExtendedProperty(PR_Flags,"1");    
    Attachment.Name = OriginalEmail.Subject;  
    mail.Subject = "See the Attached Email";  
    mail.ToRecipients.Add("glen.scales@domain.com");
    mail.SendAndSaveCopy();
