Im not sure if there is an issue with the certificate or what, but when accessing OWA externally i get as far as clicking continue when you recieve the message about the certificate not being trusted. Once i click continue i recieve page cannot be displayed.
Internally OWA works flawlessly, just out of network it doesn't. If anyone can help me i would appreciate it. Also i've checked if port 443 for SSL is open and pointing to the Exchange server. In this case it is.
