Evan,
thanks for your answer. I startet a new installation.
Now it seems, that rpc over http is working, don't know
why but it works.
I can read and write mail messages from my outlook client
when on my firewall only http and https protocols are
enabled(port 80 and 443).
But one strange behavior has remained.
1)If I login as administrator on my XP client then
rpc over http works.
If I login as an normal user than outlook can not connect
to the rpc proxy. The outlook connection status shows
always tcp/ip connections.
I tried to create the initial outlook account (XP client
connected to the Exchange subnet) when I was logged in to
the XP client as an administrator and also as an normal
user.
Any idea what's wrong ??
regards robert
