Hi
I have some problem to setup rpc over http.
I got this message when i tried to setup Outllook 2003 sp2 to connect my
computer to the remote exchange server: the name could not be matched with
a
name in the address list.
When i tried the same "username" on a other pc, connected to the same
network, no problem.
any idea ?
thanks
