Outlook entries not appearing in shared Microsoft bookings page

Hi,

I want to use Microsoft bookings as the primary calendar system for my company. We currently use Outlook calendar. However, when I click into Microsoft Bookings calendar, it only displays appointments booked via Microsoft bookings. Yes, "Events on Office 365 calendar affect availability" toggle is enabled. Microsoft bookings correctly blocks off time that is busy in Outlook, I just can't see any of those Outlook entries in Microsoft bookings. How can I fix this please? I don't want to have to flick between Outlook calendar and Bookings calendar. 

Thanks,

Irene
