Hi there,

I have a scenario with an DC that is a CA, an exchange server 2003 and an ISA server. The OWA funtion is running when you are on my network but when you want to use it from home the browser returns with "the page cannot be displayed" how to a configure OWA to be accessed from the internet?

Hello,

I just need a few details from you and we can get troubleshooting this issue.
1. Are you using SSL for OWA? Check this in ISS
2. Have you set port forwards - 443 and 80 need to be port forwarded to the exchange server that hosts OWA.
3. What authentication do you have on OWA - You can find this on the authentication section on the OWA site in ISS.

I have set OWA up for external users many times so I am sure we can resolve this issue for you.

Thanks

can you basically tell me how to check all that information. what i know is that when you try to access the OWA from the inside you just put the IP address from the exchange/exchange and a log in screen pops up then you use your users credential domain\username and password and thats it. All works well what i searched the internet i found that 443 port has to be openned but i don't know how to get there

Hello,

I would like to object as the user effectively followed my advice on point 2:

"2. Have you set port forwards - 443 and 80 need to be port forwarded to the exchange server that hosts OWA."

I should be entitled to points as my answer clearly directed him to check and enable port 443 in IIS and through his ISA server via port forwarding on router.
