I have Isa 2006 edge firewall (domain member) on windows server 2003; on this Isa I used his latest feature allowing me to publish OWA, RPC OVER HTTP & OMA on the same listener.
I have exchange 2003 on server 2003 without a front end server and the RPC OVER HTTPS & OWA are working fine but the OMA cannot connect
This is what I get when i try to get to [url]https://######.selfip.com/oma:[/url]
