Do you review Microsoft Teams usage reports?
Updated by Tiago Araújo [SSW] 1 year ago. See history
Usage analytics is quite important - it allows you to identify popular and unused teams, and helps figuring out Microsoft Teams adoption across your business (i.e. How many meetings? How many chats? etc...)
There are 2 places to check for usage reports in Teams:
Team Usage

Figure: Access team usage from "Team Settings" | "Manage Team" | "Analytics"
Tenant Usage
This is by far the most interesting and import report. You need special (tenant-level) permissions to access those usage reports.

Figure: Access tenant level usage via "Office 365 Admin Center" | "Reports" | "Usage" | "View More" (under Microsoft Teams activity section)
Now enjoy the full power of Teams usage analytics!

Figure: Click on column names to sort data (e.g. "Chat Messages")
Important: If you can't see users logins such but GUIDs instead, you will need some SysAdmin magic to make it happen. Simply follow these steps: Show user details in the reports
...and unlock the power of full O365 reporting!
