Yes. The minimum o/s requirement for OL2003's rpc/https implementation is:

* Windows XP with SP1 + KB 331320 or
* Windows XP with SP2 or
* Windows 2003 server

Any one know of any reason that I shouldn't be able to run Outlook 2003
on
a
Windows 2000 workstation and configure for Http over RPC? We don't
have
the
"connect to my Exchange mailbox using HTTP" option even though we have
Outlook 2003 install. This is just happening on Windows 2000
workstations,
all XP workstations are just fine.
