As mentioned above this message or error appears when trying to access an OWA site internally and externally using either the http://mail.mydomain.com/exchange or https://mail.mydomain.com/exchange URLs. I'm able to access the OWA site internally using the http://mail.mydomain.com/exchange but not externally using either of them. This setup consists an Exchange 2003 w/SP2 FE-BE configuration using W2K3 w/SP1 and ISA2K4 w/SP1. The FE server is configured as the Front-end server in ESM and when running the ISA Best Practices Analyzer Tool I get this error: *The secure Web server published by a Web publishing rule cannot be contacted through the SSL port * I've created both an OWA Publish rule and an OWA SSL Listener and when viewing the bridging tab I have the "Redirect requests to SSL port:" option set at 443. So I'm not sure what additional steps would I need to take to troubleshoot this issue? tia
