Exchange 2013 - The XML document ended unexpectedly

Question

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013);
service.Url = new Uri(exchangeUrl);
service.Credentials = new NetworkCredential(cred.Username, cred.Password);
FolderId parentFolderId = new FolderId(WellKnownFolderName.Calendar, mailbox);
var item = UserConfiguration.Bind(service, name, parentFolderId,
UserConfigurationProperties.BinaryData);
item.BinaryData = value;
item.Update();
Everytime when I'm calling the Exchange Web Services for Exchange 2013 I'm getting the following message...
Microsoft.Exchange.WebServices.Data.ServiceXmlDeserializationException: The XML document ended unexpectedly.
   at Microsoft.Exchange.WebServices.Data.EwsXmlReader.Read()

   at Microsoft.Exchange.WebServices.Data.UserConfiguration.Bind(ExchangeService service, String name, FolderId parentFolderId, UserConfigurationProperties properties)
I the dev environment everything is working fine, but not in integration. Any ideas? Please help.
Thanks,

It sounds like it failing to parse the SOAP response that's coming back from EWS, you need to enable tracing and have a look at the response
