Sainer × Outlook Calendar

AI-driven appointment booking against your Microsoft 365 calendars. Availability is pre-loaded before each call, bookings need a verified email, and every event carries a code so callers can reschedule later without ever seeing an event ID.

Outlook Calendar in your workflow

Before, during and after the call

Before the call

Sainer pre-loads availability across your Outlook calendars before the call.

  • Up to 20 slots per configured calendar fetched in advance
  • Respects booking window (default 14 days), durations and business hours
  • Work/school accounts only — auto-refreshing OAuth (90-day refresh window)
During the call

The AI proposes, books and reschedules appointments through Microsoft Graph.

  • Live slot lookup across every configured Outlook calendar
  • Books once the caller's email is verified (spell-and-confirm)
  • Finds and reschedules existing appointments by verification code — same-day moves supported
After the call

Bookings are immediate — no after-call write-back needed.

  • Event created via Microsoft Graph with an 8-character verification code in the description
  • Caller gets a calendar invite tied to that code
  • Conflict checks span every configured calendar to prevent double-bookings
Getting started

How it works

  1. 1

    Register an app in Microsoft Entra ID

  2. 2

    Connect Outlook to Sainer

    Sign in via OAuth with the work account whose calendars Sainer should manage. Sainer loads the calendars that account can access.

  3. 3

    Configure calendars and publish

    Pick the bookable calendars, set timezone, durations and booking window, and write the event title and description templates. You're live.
