The Microsoft Bookings app is available to many Office 365 users. The app is designed to host a shared calendar for a group of people. The calendars are in special scheduling mailboxes that are created by the Microsoft 365 substrate. Appointments in the calendar can be scheduled by people through a bookings page, which can be on the internet or confined within an organization. It’s a neat way to run an online business – if only Bookings could take in some money for all that scheduled work.
