Using the Microsoft Exchange Web Services Managed API on linux with mono te extract attachments from exchange server gives an error in the extracted attachment every 8K
At byte 8192 and 16384 ( and i guess after every 8k block ) it is loosing data.

I got only my code working in linux/mono because the TimeZoneInfo did not work on windows/mono

Example code

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

namespace Exchange_SDP_Attachment_Extracter
{
    public class PgzExchangeService
    {
        public void Extract()
        {
            ExchangeService service = new ExchangeService  (ExchangeVersion.Exchange2007_SP1,TimeZoneInfo.CreateCustomTimeZone("Central Standard Time",new TimeSpan(-6, 0, 0),"(GMT-06:00) Central Time (US & Canada)","Central Standard Time"));
            service.Credentials = new NetworkCredential("user", "pass", "domain");
            service.Url = new Uri("https://xx.xx.xx.xx/EWS/Exchange.asmx");
            ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

            FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));
            foreach (Item item in findResults.Items)
            {
                EmailMessage e = EmailMessage.Bind
                                 (service,
                                   item.Id,
                                   new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments));
                foreach ( Attachment att in e.Attachments )
                {

                    if (att is FileAttachment)
                    {
                        FileAttachment fileAttachment = (FileAttachment)att;
                        fileAttachment.Load(@"/tmp/testsdp/" + fileAttachment.Name);
                    }
                }

            }
        }
    }

    class Program
    {
         static void Main(string[] args)
         {
             PgzExchangeService pgz = new PgzExchangeService();
             pgz.Extract();
         }
      }
}
