-SBS2008 installation, self issued certificate
-owa, companyweb accesible from inside LAN or via VPN, getting warning prompt about security certificate.
When accesing from outside
accesing via http port 80 works (shows iis homepage)
accesing companyweb via port987 works (with warning prompt as expected)
accesing owa via htpps port 443 - no warning prompt, just cannot display the webpage, as if there is no certificate - any kind of certificate.
Where to look to "turn on" the certificate for owa when trying to get acces from outside lan?
