For sync service please see "I am getting 403 errors when running the Google Calendar Sync service?" in troubleshooting guide http://code.google.com/p/google-calendar-connectors/wiki/Troubleshooting For webservice could you please try disabling ssl on "EWS" and "Pulic" in IIS. If this does not solve the issue, please send us the log files.
