Check the availability of attendees

When creating a meeting request, you can check the schedule of your required and optional attendees to determine the best time for your meeting.

In the meeting request form, on the Appointment tab, type the names of the people you want to attend your meeting in the Required or Optional text boxes, and then click the Availability tab.
Note The availability chart automatically displays all your attendees' schedules on the day of your meeting with the time of your meeting highlighted. A blue bar next to a name means that that person is busy.
To change the meeting date, click the Start time or End time box, and then select a new meeting date.
To move the meeting time, click the center of the highlighted bar representing the meeting time, and then drag the meeting to a different time.
To change only the starting time of the meeting, click the green line representing the start time and drag it to the left (for an earlier start) or right (for a later start).
To change only the ending time of the meeting, click the red line representing the end time and drag it to the left (for a shorter meeting) or right (for a longer meeting).
When you finish checking availability, click the Appointment tab to finish filling out your meeting request.
