Meeting Notices different after Vista

With XP my meeting notices sent to Outlook would appear automatically in my
calendar (not accepted, but included in my calendar) so that I received
reminders of the meetings even if I had not accepted.

Now with Vista (and updated Outlook), meeting notices do not appear in my
calendar untill I open the meeting notice.

Is there a parameter setting that will allow me to return to the previous
set-up??
