Retrieve Alias from Shared Mailbox

Hi,

I would like to retrieve the alias email that would have been emailed on the Shared Mailbox but Exchange overrides the "To recipient" with the Primary email address of the shared mailbox

Example - Alias is emailed in the following shared mailbox. I would like to retrieve the "aa@alias.co.uk" email

PrimaryEmail -   aa@primarydomain.co.uk

Alias Email       - aa@alias.co.uk

I have tried accessing the header but, no luck

Following is my code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Exchange.WebServices.Data;

namespace readSharedMailbox
{
    class Program
    {
        static void Main(string[] args)
        {
            ExchangeService _service;
            try
            {
                Console.WriteLine("Registering Exchange connection");
                _service = new ExchangeService
                {
                    Credentials = new WebCredentials("*******", "********")
                };
            }
            catch
            {
                Console.WriteLine("new ExchangeService failed. Press enter to exit:");
                return;
            }
            // Office365 webservice URL
            _service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
            try
            {
                Console.WriteLine("Reading mail");
                FindItemsResults<Item> result = _service.FindItems(WellKnownFolderName.Inbox, new ItemView(1));

                foreach (Item item in result)
                {
                    EmailMessage message = EmailMessage.Bind(_service, item.Id);
                    Console.WriteLine("Reading items");
                    Console.WriteLine(message.ToRecipients[0].Address.ToString());
                    /* Reading the Header

                    foreach (var property in message.InternetMessageHeaders)
                    {
                        Console.WriteLine(property.Name);
                        Console.WriteLine(property.Value);
                    }
                    */
                }
                Console.WriteLine("Exiting");
                Console.ReadLine();
            }
            catch (Exception e)
            {
                Console.WriteLine("An error has occured. \n:" + e.Message);
            }
        }
    }
}

Every day i learn something new.
