Database management scopes will only be applied when a user connects to a server running Exchange 2010 SP1 or later. Servers running a version of Exchange prior to Exchange 2010 SP1 won't apply any roles from a role assignment linked to a database scope. Database management scopes also won't be visible to the Get-ManagementScope cmdlet when it's run from a pre-Exchange 2010 SP1 server.
