Webex Scheduler Architecture Overview

The above diagram shows the site admin and individual authorization scenarios for Webex Meetings from Microsoft 365.

The site administrator authorizes Webex to access Microsoft 365 administrator tenant data from Cisco Webex Site Administration or Control Hub (optional).
An individual authorizes permission for Webex (if admin doesn’t authorize) and connects their Microsoft account with their Webex account.
Webex subscribes to calendar changes from Microsoft.
A user adds a Webex meeting to a Microsoft Calendar event, updates the time or topic, or copies an event to another date and time.
The Webex add-in service receives Microsoft Calendar notifications and syncs data with Webex.
