Re: Accessing OWA via a Proxy/Relay Server
Sorry for my slow reply on this. Per your suggestion, we tried explicitly adding our domain as the default domain for the Exchange page in IIS, and still no go.

Try adding your domain as the default domain, even though it may be set to default. Not exactly. We are not running Exchange on the new proxy server, just win2k, IIS, and ISA. We are able to access OWA on the Exchange server from internal clients with no problems by addressing it directly: http://exchangeservername/exchange; Problem is trying to get to OWA via the new server's IIS from external clients (http://newservername/exchange). We tried Ed's suggestion to login from an external client using domain/account as the ID and still got the 403 unauthorized error. We are using basic (clear text) authentication.
