Why do I keep getting 404 errors in Outlook Web Access?
We encountered this problem during our initial testing. We had configured SSL-Explorer to listen on a non-standard port and started to get 404 errors in OWA. The problem lies with OWA not processing the Host header correctly when the non-standard port is not being listened to by the OWA server.
This was resolved in testing by forcing the OWA server to listen on the non-standard port. If you need OWA to still listen on 443 then go to the advanced options on the "Web site" property page and create an additional web site identity which listens on your non-standard port.
