If you created the meeting, when you hover the mouse over the appointment in your calendar view and a pop-up will show whether your invitees have accepted. This may not show everyone for large meetings.
To see everyone, open the appointment and go to the schedule tab. To the right of each attendee (between their name and free/busy info) will be an icon indicating their status: a check for accepted, an 'x' for declined, or a "?" for needs action. |
