Hi everyone; I have set up exchange and OWA and they are working just fine, and users are able to use OWA inside the LAN. But, they can't access their mailbox using OWA from home. I have followed the instructions in the learning zone, the set up of OWA is done exactly the same way. I was wondering if there was anything else beside these steps that needs to be done and if not, any idea about what I may have done wrong? thanks, Farshad
