Outlook Show Busy From Other Calendar. With office 365 calendar, people can see your free/busy times in order to choose a meeting time. What permissions other people can have to your calendar.
You can’t add an internet calendar in outlook 2016, outlook 2019 and outlook for office 365. I’ve done a lot of research on this, such as changing the permission of other calendar folder, but i haven’t found any way to display free and busy information for.
