In a big company or government network that uses
Outlook with a Microsoft Exchange Server, you can also see the
free/busy times for your colleagues’ calendars. Look for the Meeting Planner
on the Scheduling button.
All Attendees are listed in
the column on the left hand side. The little envelope by their name
reminds you that your invitation will be emailed.
To invite additional attendees, you can type their email address on
the next blank line in this list. Attendees can be Required or
Optional. Some rooms have their own calendars, so that you can
schedule them. You would type the name of the room as if it is an
attendee, then choose Resource from the list.
