Set vacation time and planned absences
If you’re going on vacation or leave and want to disable check-in prompts while you’re away, go to Preferences - Planned Absences and click on the days when you won’t be checking in.
You also have the option to check in as “Absent” when you receive your check-in reminder.
How to set other team members' absences
Administrators can set users' absences from the Teams & People page by selecting "Planned Absences" from the user's menu.
