-------------------------------------------------------First - I apologize for 
not beeing more spesific ...

The Exchange is sitting in our DMZ-domain, Outlook clients in our
corporate network wich is behind a firewall (this network is being
NAT'ed). Further there is no VPN connection and unfortunately we're still
running Outlook XP here so I guess RPC over HTTP is not available to us.

Outlook is configured to always prompt for user, password and domain and
I've been dooing some regedits setting Rpc_Binding_Order and such - all to
no avail.

And - there I am - been searching for a working solution for days - and
now  - stuck!

Any pointers is highly appreciated

regards,
Sture
