Outlook Calendar connects through Microsoft's standard OAuth login (Microsoft Graph under the hood). Personal Microsoft accounts, Outlook.com, and Microsoft 365 work accounts all work — you sign in once and the agent can read free/busy and write events on the calendar you choose.
Once connected, the AI agent quotes only times you're actually free, books appointments with the visitor as the invitee, and handles cancellations and reschedules when an email is on file.
