Teams can be a very active workload within Office 365. The Teams User Activity report gives you aggregate data based on statistics gathered on a daily basis. This is a powerful report to get a true sense of the scale and importance of Teams within your organization. For example, review the total number of Team Chats or Calls to get a complete picture of usage for Teams.
The Chart will show how this tracks over time and the time scale can be changed.
Below the Chart is a daily entry for all the activities for a user within the given timeframe. Use this to review particular users or export them for further analysis.
As with all of the reports, this information can be customized, filtered and scheduled.
