problems starting outlook express

[mitch]

I've just installed win2k and Office on a clean system. I
am using RoadRunner with an onboard ethernet. Connects to
the internet fine. When I try to start up Outlook Express
I get a pop-up from 'Identity Switch Cancelled'
saying "The current identity could not be changed because
one of the applications was unable to switch. Close any
open dialog boxes in the other applications before trying
again"

Since I don't have any other applications running I'm
assuming this is a setup proble. Can anyone help me with
this?

thanks in advance,
Mitch
