Are the client machines members of the domain?

If not - then that is by design. Outlook needs to authenticate.

If they are then you can tweak the authentication settings to allow the
cached credentials to work. The solution should be transparent to a user
on a domain member machine.

by RPC over HTTP when they are away from the office with their

I am wondering if there is anyway to force OL2k3 to use their users
local credentials to login via RPC over HTTP on the local LAN instead of
prompting them for a username and password each time. It's already

them away.. ;)
