                        // 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);
                    else // Attachment is an item attachment.

              //  }
        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;
