Per-Team Activity Data Available via Graph API
A new Microsoft Graph query makes it easy to fetch per-team activity data for reporting. You can also fetch the data with the Microsoft Graph PowerShell SDK. The data goes back a maximum of 90 days and is at least two days old when you fetch it. Those facts are easy to live with. What’s not so good is that the activity data focuses exclusively on channel activity and avoids everything else which happens in Teams.
