[dba-Tech] Outlook Question

I don't use Outlook much, but I used to a lot, so I know my around it. But
I have never used it in a situation where one or more employees would need
access to one another's calendars (for example, to check someone's
availability for meeting. One particular worker, the Planner, would need
access to everyone's calendars, for example to book appointments for more
than one doctor within the office.

Now what would be really cool is if there were also a way to "overlay"
several calendars and get a visual representation of the availability of
any combination of the workers, so you could say, "Show me the times when
these five people are all available for a one-hour meeting." And it would
present them in some graphical way on a virtual calendar. Can that be done
with Shared Outlook or whatever the product is called?

TIA,
Arthur
