How to sync Outlook calendars with Ronspot using Microsoft 365
This guide provides detailed, step-by-step instructions for connecting Microsoft 365 to Ronspot to enable near-instant meeting synchronisation.
Contents
About The Integration
The Microsoft 365 integration allows Ronspot to securely connect to your Microsoft tenant and synchronise meetings bi-directionally using the Microsoft Graph API. This ensures that any bookings created or updated in Outlook are reflected in Ronspot, and vice-versa, through a near-instant, asynchronous sync process.
This seamless integration keeps calendars aligned, reduces manual adjustments, and ensures that meeting updates are automatically mirrored between both systems without requiring ongoing intervention. For organisations using Ronspot for workspace or parking management, this meeting sync provides accurate, real-time availability based on users’ Outlook schedules.
Notes & Prerequisites
This integration replaces our legacy Microsoft Exchange integration and addresses two limitations:
-
Delayed email delivery of calendar invites, which could take up to two minutes and increases the potential of double-bookings of the same time period.
-
Exchange’s restriction on editing meetings, caused by the absence of the unique meeting ID when an organiser updates a meeting from Outlook.
Before setting up the integration, please ensure you have access to the Azure portal.
