MS Teamwork: Delete an Online Meeting

See more Microsoft Teams Examples

Demonstrates how to delete a Microsoft Teamwork Online Meeting

Note: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.
