Microsoft 365 Reports in the admin center - OneDrive for Business 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 for Business 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.


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.

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.
