The Scheduling Assistant
4. Try It: Review the Scheduling Assistant
The Scheduling Assistant shows the Contact List on the left and their Free/Busy calendars on the right. Three Contacts have been added to this Meeting Request, so there are three Calendars shown side by side on the same day..

Elizabeth already has an Event scheduled at this time. The border is purple so she will be AWAY. Clair is also unavailable. She will be BUSY.

There is no information for Glen Glick: his Calendar does not have any Events.

So, this day and time won't work.

Keep going...
