                    exchange.Credentials = new WebCredentials("user", "password", "domain");
                    exchange.TraceEnabled = true;
                    exchange.TraceFlags = TraceFlags.All;
    
                    exchange.AutodiscoverUrl("mail-id", RedirectionUrlValidationCallback);
                    exchange.Url = new System.Uri("https://URL/EWS/Exchange.asmx");
    
                    exchange.KeepAlive = false;
                    exchange.Timeout = 900000;
                    WriteToFile("Connected to Exchange Server : " + exchange.Url.Host);
    
      TimeSpan ts = new TimeSpan(0, 0, -15, 0);
                    DateTime date = DateTime.Now.Add(ts);

                    if (exchange != null)
                    {
                        FindItemsResults<Item> findResults = exchange.FindItems(WellKnownFolderName.Inbox, filter, new ItemView(999));
