Recommended route

Dashboard-managed connection

Your AI writes appointments to the selected Microsoft 365 calendar; availability checks fall back to a clearly labelled request when unavailable. Availability support is newer than Google Calendar. A failed read becomes a request for confirmation, never a claimed booking.

Account ownership and data boundaries

The route sends only the event fields needed for the action you configure. Provider credentials stay in the approved connection or are sealed by First AI Employee where the guide explicitly says so.

Your provider and automation accounts remain yours.
A successful transport test is not the same as a verified provider write.
The pages never claim a native or two-way sync unless that exact capability exists.
