I've looking for a way to restrict OWA access externally. One method which intrigues me is this:
http://www.leederbyshire.com/Articles/Block-Or-Allow-OWA-Depending-On-Location-2007.asp Although written for Exchange 2007 (this environment is Exchange 2010), the files exist and it seems that it would work. Other solutions involve setting up a second IP address and setting up another virtual directory. This seems to be the less complicated of any other method I've found. Would anyone care to chime in with an opinion? -Paul
