Hi All, I am running Exchange 2003 (Standard and patched) and OWA over SSL and works fine. I am trying to get OMA working. I followed the KB 817379, where I created a different virtual directory (excchange-oma, and followed to the dot the steps in the artcle). I am testing it through a web browser. I take it that I can not do a http://myserver/exchange-oma as there is an IP access restriction in place (as per KB 817379). Then again the Default Website access is SSL enabled (by default , when you configure SSL OWA access), so I disabled SSL on the Default Website but enabling SSL access on the Virtual Directores except for OMA and exchange-oma (virtual directories). I also edited the registry and set ...\MasSync\parameter value to \oma (instead of \exchange-oma), just in case. When I do a http://myserver/oma, it gives " A System error has occurred while processing your request..." after entering the logon credentials. What am I missing? Thanks very much in advance. Patrick.
