When a user synchronizes a mobile device with Microsoft Exchange Server 2007, an HTTP response code is returned for each synchronization. The HTTP response code is determined by the success or failure of the synchronization. You can examine the HTTP response code to determine whether the synchronization request was successful. If the synchronization request was not successful, the HTTP code can indicate why the request failed. This topic lists the HTTP response codes and the meaning of each code.
