Office 365 (Outlook Client for Windows) - Create an Appointment
Appointments are activities that you schedule in your calendar that do not involve inviting other people or reserving resources.
1. Navigate to your calendar by clicking on the calendar icon in the top left of Outlook.
2. Select New Appointment or click Ctrl+N. You can also right-click a time block in your calendar grid, and then click New Appointment.
3. Enter a subject, location, start time, and end time.
4. Select Save & Close to save your appointment.
Note: By default, Outlook starts and ends appointments on the hour or the half hour. If you'd like to enter a custom time, for example 12:22 p.m., click in the start or end time fields and type in the exact time you need.
