I have tried the solution in this article to enable OMA access to the mailbox store via http, but it seems like this is not working.
Rather than going into the specifics of my setup i thought i would just ask if people (have/think will work) the following setup would work.
The ISA Firewall and exchange 2003 server are all installed on the same server.
There are 3 external IP addresses (1 VPN, 1 Mail, 1 NAT (default primary) )
There are 2 interal IP addresses, one used for normal network operations, and one used for exchange smtp
ISA Publishing rules point to the internal exchange IP address
ISA Publishes OWA to the internal exchange IP address, and uses SSL form based authentication
IIS has been configured to host the default web site on the internal exchange IP address
Now with this setup i thought that activating OMA was just going to involve enabling it in the ESM and addding the path to the OWA publishing rule, granting a path to /OWA/*. Any help / questions would be appreciated
Exchange on the firewall isn't supported. It *might* work, but there are sorts of security problems, so that I haven't even worked out this scenario. The SBS team is working on some hacks to allow it to work, but its taking them quite some time, so I suspect its not going to be easy to make it even half secure.
