After you make changes to a meeting, you're prompted to send a meeting update to other attendees.
If you only want to change the recurrence options for an appointment or meeting, you can click the recurring item in your calendar. Then, in the Options group on the Item Series tab, click Recurrence and change the options you want.
You can edit events the same way you edit appointments or meetings, except if it's an all-day event like a conference. By default, all-day events are set to run from midnight to midnight. However, this range does not appear in your calendar as a "busy" range.

3.Open the event from your calendar.
6. Clear the All day check box.
7.Enter the Start Time and End Time, then click Save and Close.
