Set up OWA via the internet

OWA, Synchronization, Outlook Web Access, Outlook, Mobile

Hi,

I am using windows server 2003 SP2. The previous IT person for some reason set up OWA via our intranet and not accessible externally i.e. via the internet from outside the company. Is there a simple way to set OWA to be accessible externally. I have SSL certificate from go daddy.

One of the reason why this needs to be change is so we can sync exchange emails to mobile devices such as PDA, XPA.

The previous IT person was apparently security-conscious as you should also be. Opening OWA to the internet is obviously not without its risks so you need to be prepared. The best model is to use an ISA server to be a front-end application firewall to the OWA server. The ISA server will be able to securely publish the OWA webpage. You will need to open the appropriate firewall ports (http/https) and map a public IP address to the ISA server published OWA interface. See this Microsoft article for more details.
