Our users are not able to access their mail via OWA when connecting from an external site. Internally everything works ok. We have a load balancer and 2 front end servers. We checked the NATing and everything seeems to be ok. When the users connect from an external address, it seems that it is connecting because they see the unsecure (HTTP://
)address changing to a secure one( HTTPS://
)but as soon as it's changing to HTTPS://
the users receive a "page cannot be displayed" message. The SSL 443 port is enabled on the firewall.
