Hello,

I have an ISA Server standalone, and behind it, is my domain, sort of: internet--->my router--->ISA server --->my domain

I am running a CA in my domain.

I imported a certificate called "mail.mydomain.com" to the Computer certificates console within this ISA Server. To achieve this I first exported the certificate from the actual Exchange mail server inside the LAN, then imported it in the ISA machine.

The issue is that when I am creating a WebListener in a publishing rule (publishing OWA and ActiveSync), it cannot access to the certificates of this ISA Server. It looks like it is not recognized.

Hi,

You could refer to the article below to check if your certicate meets the requirement.
