If your report is empty and you receive this message There is no data for this chart, there are a few reasons for this, including:
The data is being filtered in a way that no data is returning. You might need to edit your report and modify the filters.
The data might require access to the Security and Audit Logs that may not have been configured. Check your 365 Analytics settings.
The data has not been collected as the data collection needs to be authorized.
You may need to reauthorize your tenant. For information, see How to connect your 365 Tenant for data collection.
If you've completed these steps and still have the notification or the report is empty, contact our Support team.
