365agents connects natively to Microsoft Outlook / Microsoft 365 Calendar via OAuth. Your AI agent reads your live Outlook calendar during every call, proposes available times when callers want to book, and writes the confirmed booking back to Outlook in real time. No manual scheduling on your end.

What this makes possible

Live availability — the AI sees exactly what's on your Outlook calendar as the caller is speaking

Works across Microsoft 365 tenants — shared calendars, departmental calendars, individual calendars

Honors meeting rules — buffer times, out-of-office, recurring meetings, and calendar categories

Multi-person booking — if the appointment requires multiple attendees, the AI can find the first common open slot

Teams meetings auto-created — for remote appointments, a Microsoft Teams meeting link is generated and included in the confirmation

How a real call flows

•Caller: "I need to schedule a consultation."

•AI checks Outlook, proposes available times across the right provider or team member

•Caller picks a time, AI collects required details

•AI writes the Outlook event with the caller's information, triggers the Teams invite if remote

•Caller gets confirmation text with all details; your team sees the appointment on Outlook immediately

How to connect

•Admin dashboard → Integrations → Microsoft 365 Calendar

•Click "Connect" and sign in with the Microsoft 365 account you want the AI to book against

•Grant the requested calendar read / write permissions

•Pick which calendars the AI can read, which it can write to, and any per-calendar rules

•Test with a call to your agent

Who this is for

•Any business on Microsoft 365 / Office 365

•Enterprises with Outlook as the default calendar

•Healthcare and legal practices running on Microsoft 365 without a dedicated PMS

•Professional services firms with Teams-based remote consultations
