Microsoft 365 Reports in the admin center - OneDrive usage

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, the OneDrive card on the dashboard gives you a high-level view of the value you are getting from OneDrive in terms of the total number of files and storage used across your organization. You can then drill into it to understand the trends of active OneDrive accounts, how many files are users interacting with as well as the storage used. It also gives you details for each user's OneDrive.

How do I get to the OneDrive usage report?

  1. In the admin center, go to the Reports, and then select Usage.
  2. From the dashboard homepage, under Reports, select OneDrive.

You can view the usage in the OneDrive report by choosing the Usage tab.

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.

The OneDrive usage report can be viewed for trends over the last 7 days, 30 days, 90 days, or 180 days. However, if you select a particular day in the report, the table will show data for up to 28 days from the current date (not the date the report was generated).
