Outlook integration

Is exchange server a requirement when you just want to experiment/demo with the integration between crm and outlook? Contacts and to do works already without a exchange server! Environment: CDO is installed 3.6 Navision Attain Otlook 2000 I have received serveral errors in Navision.

Apperantly it is not required in a demoenvironment(Heard from Navision Sweden), Now I wonder how I can set up a demo account in outlook, anyone?
