Hi @globaladmin
According to the Microsoft Graph documentation, change notifications for Microsoft Teams resources using Microsoft Graph enable you to subscribe to changes (create, update, and delete) to a resource. Microsoft Teams supports two types of change notifications:
- Change notification to track all changes related to a resource across the tenant: For example, you can subscribe to changes in messages in any channel across the tenant and get notified whenever a message is created, updated, or deleted in any channel in the tenant. These notifications may have licensing and payment requirements, such as change notifications for messages and membership.
- Change notification to track all changes for a specific resource: For example, you can subscribe to changes in messages in a particular channel and get notified whenever a message is created, updated, or deleted in that channel. For details about which resources support which types of change notifications, see Microsoft Graph change notifications.
