If you use Gmail for work or school and create an 'out-of-office' event, anyone who emails you will get your out-of-office status.
Gmail gets your calendar status when you create an 'out-of-office' event.
The 'out-of-office' event must span the entire day or extend past your regular working hours. Learn how to set your working hours and availability.
Important: The sender must have permission to view your calendar or they won’t get your out-of-office status. To make sure that others have access permission, you must share your calendar.
