  • How to configure external URL in Exchange 2003 OWA

    I am simply trying to change the external URL displayed / redirected when someone accesses the site from the outside. Example I want "https://ExtURL.domain.com/Exchange" when the actual server name is IntURL.domain.local.

    You don't have any control over that.
    Exchange 2003 will accept anything/exchange - so you just need to tell the users to enter the correct URL.

    If your SSL certificate is host.example.com then they enter https://host.example.com/exchange

    Internally they can use host.example.local/exchange but will get an SSL warning. You can avoid that with a split DNS system so that host.example.com resolves internally to the internal IP address.

      Thank you for the reply. That's what my expectation was. However, when I turn forms based access on and type the same URL in externally, it translates it to the internal server name, which will not resolve externally. This results in something like a server unavailable error.

      Internally it works like a charm. But that is because the server name will resolve internally.

      I should clarify, the system works perfectly, inside and out, if forms based access is not used. Not sure if that helps.

        The only time that Exchange "corrects" the URL is when you access another server than the one that your mailbox is on.

        So if you have two servers, access OWA on server1, but your mailbox is on server2, then Exchange will redirect you to the other server, and that would be the server's real name.

        If you only have one server, then something is wrong with the OWA configuration. FBA doesn't change anything with regards to the URL.
