Office 365 (Outlook 2013 / 2016 / 2019 for Win) - 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 Outlook calendar.
***NOTE - Beginning with Outlook 2016, icons have replaced the words (if you have Compact Navigation enabled) as per the second image below.
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.
