Publishing OWA via ISA 2006

Many Organizations will like to use ISA server as one of their security. Here we will be looking how we can push Outlook Web Access through ISA 2006.

Lets get started by opening ISA Management console.
Right click on Firewall in left panel and point towards New > Exchange Web Client Access Publishing Rule
 

Click on Next.

You will be given with a new window, and we are suppose to put a user friendly name for our rule. Lets name it OWA Publishing Rule.

Click on Next.

Here we need to select the version of OWA that we need to publish, as in this case we are discussing Exchange 2003 server so we will be selecting Exchange server 2003 from version dropdown list.

In service section, we will select "Outlook Web Access" and not others as they will be discussed in later articles one by one.

Click on Next.

Here we will select 1st option i.e., "Publish a single web site or load balancer"
 

Click on Next.

Now we will select the type of connection that we are going to make, here we will use a connection without SSL and hence will select "use non-secured connections to connect the published web server"

Click on Next.

Here we will enter the name that users will use to access OWA. I have created a host record in my DNS with name as "mail" and hence its "mail.msexchange.in" in my case.

Secondly, we will select the exchange server or we can manually enter the IP address of exchange server in second box.
