            // CalendarService oCalendarService = GAuthenticate();

            //Prevents This Error
            //{"The remote server returned an error: (417) Expectation failed."}
            System.Net.ServicePointManager.Expect100Continue = false;

            //Save Event
            oCalendarService.Insert(oCalendarUri, oEventEntry);

Comment the Proxy part it should work:

////Use Proxy 
//GDataRequestFactory oRequestFactory = (GDataRequestFactory)oCalendarService.RequestFactory;
//WebProxy oWebProxy = new WebProxy(WebRequest.DefaultWebProxy.GetProxy(oCalendarUri));
//oWebProxy.Credentials = CredentialCache.DefaultCredentials; //oWebProxy.UseDefaultCredentials = true;
//oRequestFactory.Proxy = oWebProxy;
