LobbyStack plans to support Microsoft 365 and Outlook Calendar with the same real-time booking flow available for Google Calendar today. When a caller asks for an appointment, the AI will check your Outlook calendar for open slots and book directly — no manual entry required.
Outlook Calendar integration is not yet available. The option appears in Settings > Integrations, but the Connect button is currently disabled. This feature is on the roadmap and will be enabled in a future release.

What Outlook Calendar will do

When the integration launches, it will work the same way as the Google Calendar integration:
  • The AI checks your Outlook or Microsoft 365 calendar in real time during every call
  • Open slots are offered to the caller based on your availability
  • Confirmed appointments are written directly to your calendar
  • You select which calendar to use after connecting your Microsoft account
  • Connection status is shown in Settings > Integrations, with options to reconnect or disconnect
The setup will use Microsoft’s OAuth flow, so you authorize access once from your LobbyStack dashboard with no manual configuration.

How to be notified when it’s available

There are two ways to stay up to date:
  • Dashboard: Check Settings > Integrations — the Outlook Calendar card will become active when the integration is released
  • GitHub: Watch the LobbyStack repository for release notes and updates

Use Google Calendar in the meantime

If you need calendar-based booking today, Google Calendar is fully supported. The setup takes a few minutes and provides the same real-time availability and booking experience that Outlook Calendar will offer.
