Reduce the end time of short appointments and meetings by a specified number of minutes

This policy setting allows you to specify how many minutes to reduce the end time of a short appointment or meeting by when a user creates an appointment or meeting. A short appointment or meeting is one that lasts for less than one hour. If you enable this policy setting, you specify the number of minutes to reduce the end time of a short appointment or meeting by when a user creates an appointment or meeting. The user can’t change this value by going to File > Options > Calendar. Note: You should also enable the “End appointments and meetings early” policy setting. If you disable or don’t configure this policy setting, the default value of 5 minutes is used or whatever the user specifies by going to File > Options > Calendar. Note: This policy setting only applies to subscription versions of Office, such as Microsoft 365 Apps for enterprise.
