i am installing Unity 4.2.1 and i am having serious issues with the permissions wizard. When I go to choose a mailstore, i get a message teling me it could not find any windows 2000 mailstore. I am fllowing the Unity install PDf and have installed Exchange 2000. When i look under the System Managemnet in Exchange, I do not see the server option. Has anybody come accross this before and if so, have you got a workaround?
