Hi, I do not know why you changed the authentication to anonymous access. Base on some article, Exchange Web Service has BasicAuthentication and WindowsAuthentication. The default settings is Windows Integrated Authentication. So I recommend you change the authentication to Windows Integrated. Default settings for Exchange-related virtual directories in Exchange Server 2007 http://msexchangeteam.com/archive/2008/02/01/447989.aspx Set-WebServicesVirtualDirectory http://technet.microsoft.com/en-us/library/aa997233.aspx Regards, Xiu
