Open OWA to Internet
- I have a mixed Exchange2003/2007 environment. One X2003 server inside firewall and one X2003 Front End for OWA. One X2007 server with CAS/HUB/Mailbox roles installed on Windows Server 2003 sitting inside the firewall. OWA is working internall using https://server.domain/owa. However internet users get "cannot display this webpage" when using the same link. How do I set up DNS records to allow internet users to access OWA?

- No Issues. You can do the same way. The only difference will be a port forwarding from your Firewall to the internal IP of the CAS server.
Additionaly need to take care of the SSL http://technet.microsoft.com/en-us/library/bb123583.aspx

- Hi,
Since you don't have an ISA server to publish the OWA, you can also map public IP address to your private address of CAS by fireware.
And If you have a Cisco route, you have better contact Cisco support to get better help.

- In brief , Create a A record on the public DNS . Map the IP to the firewall and from there do a port forwarding on 443 to the front end server.

Raj - I need to publish the Ex2007 CAS for OWA access, not Ex2003. And we're not using ISA Server.
