hi,

I have a w2k server sp3 with ex2k sp3 on installed. I configured my server for owa, dns,.. but it won't work from outside the office.
When i look on my firewall log, i see that my incoming requests or blocked.

Anyone can tell me which ports f I have to open on my firewall for OWA ?

Thx

For OWA the only ports you need to have open through your firewall to the Exchange server hosting OWA is 80 and 443 (The latter only if you are using SSL (https) for OWA). This is provided that the IIS server hosting OWA is using the standard ports. This can be review through the IIS console.

Other things to look out for is that your internet client can successfully resolve the name used for accessing OWA to the internet IP address that the OWA server is available on.
