My department creates a shared calendar for everyone to enter their out-of-office times. This requires duplicate entry for those of us who keep all our info in our own Exchange calendar.

Is there a way in Exchange to create a View that's simply a combination view of multiple users' calendars?

For example, we would create a view with all the departments' users calendars combined, but only those marked "out of office". Ideally, the subject line would also include the user's name, but this would not be 100% necessary.
