String MailboxToAccess = "myemailaddress";
ExchangeService service = new Microsoft.Exchange.WebServices.Data.ExchangeService(ExchangeVersion.Exchange2007_SP1);
List<SearchFilter> searchFilterCollection = new List<SearchFilter>();
            searchFilterCollection.Add(new SearchFilter.ContainsSubstring(ItemSchema.Subject, "EDI"));
            searchFilterCollection.Add(new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));
            SearchFilter searchFilter = new SearchFilter.SearchFilterCollection(LogicalOperator.Or, searchFilterCollection.ToArray());
            service.Credentials = new NetworkCredential("myemail", "pwd");
            service.AutodiscoverUrl(MailboxToAccess, adAutoDiscoCallBack);
            FolderId FolderToAccess = new FolderId(WellKnownFolderName.Inbox, MailboxToAccess);
            ItemView ivItemView = new ItemView(50);
            FindItemsResults<Item> FindItemResults = service.FindItems(FolderToAccess, searchFilter, ivItemView);
            PropertySet ItemPropertySet = new PropertySet(BasePropertySet.IdOnly);
            ItemPropertySet.Add(ItemSchema.Body);
            ItemPropertySet.RequestedBodyType = BodyType.Text;
///error here??????
                EmailMessage message = EmailMessage.Bind(service, new ItemId("AAMkA"), new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments));

                // Iterate through the attachments collection and load each attachment.
                foreach (Attachment attachment in message.Attachments)
                {
                    if (attachment is FileAttachment)
                    {
                        FileAttachment fileAttachment = attachment as FileAttachment;

                        // Load the file attachment into memory and print out its file name.
                        fileAttachment.Load();
                        Console.WriteLine("Attachment name: " + fileAttachment.Name);

                        // Load attachment contents into a file.
                        fileAttachment.Load("C:\\temp\\" + fileAttachment.Name);

                        // Stream attachment contents into a file.
                        FileStream theStream = new FileStream("C:\\temp\\Stream_" + fileAttachment.Name, FileMode.OpenOrCreate, FileAccess.ReadWrite);
                        fileAttachment.Load(theStream);
                        theStream.Close();
                        theStream.Dispose();
                    }
                    else // Attachment is an item attachment.
                    {
                        // Load attachment into memory and write out the subject.
                        ItemAttachment itemAttachment = attachment as ItemAttachment;
                        itemAttachment.Load();
                        Console.WriteLine("Subject: " + itemAttachment.Item.Subject);
                    }
              //  }
               
            }
           
        }
        internal static bool adAutoDiscoCallBack(string redirectionUrl)
        {
            // The default for the validation callback is to reject the URL.
            bool result = false;

            Uri redirectionUri = new Uri(redirectionUrl);

            // Validate the contents of the redirection URL. In this simple validation
            // callback, the redirection URL is considered valid if it is using HTTPS
            // to encrypt the authentication credentials.
            if (redirectionUri.Scheme == "https")
            {
                result = true;
            }

            return result;

If you're searching for the email, not sure how you can use this:

PropertySet ItemPropertySet = new PropertySet(BasePropertySet.IdOnly);
            ItemPropertySet.Add(ItemSchema.Body);
            ItemPropertySet.RequestedBodyType = BodyType.Text;
///error here??????
                EmailMessage message = EmailMessage.Bind(service, new ItemId("AAMkA"), new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments));
since you haven't found the email yet.  You'll need to iterate through the FindItemResults, verify that it is of type 'EmailMessage' and then use the properties to get the attachments.
foreach (Item myItem in FindItemResults.Items)
{
    if (myItem is EmailMessage)
    {
        var message = myItem as EmailMessage
        // Iterate through the attachments collection and load each attachment.
                foreach (Attachment attachment in message.Attachments)
                {
                    if (attachment is FileAttachment)
                    {
                        FileAttachment fileAttachment = attachment as FileAttachment;

                        // Load the file attachment into memory and print out its file name.
                        fileAttachment.Load();
                        Console.WriteLine("Attachment name: " + fileAttachment.Name);

                        // Load attachment contents into a file.
                        fileAttachment.Load("C:\\temp\\" + fileAttachment.Name);

                        // Stream attachment contents into a file.
                        FileStream theStream = new FileStream("C:\\temp\\Stream_" + fileAttachment.Name, FileMode.OpenOrCreate, FileAccess.ReadWrite);
                        fileAttachment.Load(theStream);
                        theStream.Close();
                        theStream.Dispose();
                    }
                    else // Attachment is an item attachment.
                    {
                        // Load attachment into memory and write out the subject.
                        ItemAttachment itemAttachment = attachment as ItemAttachment;
                        itemAttachment.Load();
                        Console.WriteLine("Subject: " + itemAttachment.Item.Subject);
                    }
            }
    }
}
