MS Teamwork: Update an Online Meeting
See more Microsoft Teams Examples
Demonstrates how to update a Microsoft Teamwork Online MeetingNote:If using Application access (i.e. client credentials) which is what this example is doing, then you'll need to "Configure application access to online meetings or virtual events" See https://learn.microsoft.com/en-us/graph/cloud-communication-online-meeting-application-access-policy#configure-application-access-policy
For example, here's our Powershell session to setup the policy.
