Microsoft Bookings needs your admin to enable it tenant-wide, and its staff concept can't reach outside your own organization. Riverli works the moment you sign in — with anyone, on any calendar.
Microsoft Bookings features shown reflect Microsoft's publicly documented configuration behavior as of 2026 and are subject to change — see Microsoft's documentation for current details.
Microsoft Bookings has to be explicitly turned on for your organization by an admin, and even then, individual users can still be blocked from creating booking pages by policy. Setting changes can take up to 24 hours to apply. None of that is a product limitation — it's how Microsoft 365 tenant administration works, and it means getting Bookings actually usable often means opening a ticket and waiting.
There's a deeper limit too: Bookings' staff role only supports people who are licensed users inside your own tenant. There's no way to add a colleague at a partner company, a contractor, or anyone outside your organization as a co-host — the role simply doesn't reach that far. Riverli was built around the opposite assumption: the people you need on a call rarely all work at the same company, so co-hosting shouldn't require them to.
