Microsoft 365 Reports in the admin center - Active Users
The Microsoft 365 Reports dashboard shows you the activity overview across the products in your organization. It enables you to drill in to individual product level reports to give you more granular insight about the activities within each product. Check out the Reports overview topic.
For example, you can use the Active Users report to find out how many product licenses are being used by individuals in your organization, and drill down for information about which users are using what products. This report can help administrators identify underutilized products or users that might need additional training or information.
You must be a global administrator, global reader or reports reader in Microsoft 365 or an Exchange, SharePoint, Teams Service, Teams Communications, or Skype for Business administrator to see reports.
How to get to the Active Users report
In the admin center, go to the Reports > Usage page.
Select Office 365 > Active users from the drop-down.
Interpret the Active Users report
||The Active Users report can be viewed for trends over the last 7 days, 30 days, 90 days, or 180 days. However, if you view a particular day in the report, the table (7) will show data for up to 28 days from the current date (not the date the report was generated).
||The data in each report usually covers up to the last 24 to 48 hours.
||The Active Users chart shows you daily active users in the reporting period separated by product.
The Services chart shows you count of users by activity type and Service.
||On the Active Users chart, the x axis shows the selected reporting time period and the y axis displays the daily active users separated and color coded by licence type.
On the Services activity chart, the X axis displays the individual services your users are enabled for in the given time period and the Y axis is the Count of users by activity status, color coded by activity status.
||You can filter the series you see on the chart by selecting an item in the legend. Changing this selection doesn't change the info in the grid table.
||You can also export the report data into an Excel .csv file, by selecting the Export link. This exports data of all users and enables you to do simple sorting and filtering for further analysis. If you have less than 2000 users, you can sort and filter within the table in the report itself. If you have more than 2000 users, in order to filter and sort, you will need to export the data.
||You can change what information is displayed in the grid table with column controls.
