I'm running OWA 2003 and trying to set it up with HTTPS. Currently users on the outside access their mail by using http://mail.abcd.com/exchange
I have configured the certificate on the exchange, installed it on the ISA box and created a web filter that uses https and this certificate. The Exchange is not using forms based authentication, but I have it enabled at the ISA level.
Internally I can access the https site fine, but from the outside I get an Internal Server 500 error and a message The target principal name is incorrect.
I've changed the names in the ISA rules but I'm missing something.
any ideas or help would be appreciated.
