But when i m trying toaccess "https://ex2k7.abc.com/owa" from internet it is not working.Pls. help me and suggest the right configuration. I am not using any firewall.

Hi, from outside, where does your real or Public IP pointing to ? you should not point or redirect your external requests for OWA to your edge server, since edge server has nothing to do with HTTP Requests, you need to redirect your external OWA requests from your firewall to your CAS Server, not to the edge server. please let me know if this was the case of your problem or not.
