The “Audit activities” for Microsoft 365 section offers a comprehensive report of all activities from the Unified Audit Log within your Microsoft 365 tenant. This report serves as an initial reference, which you can refine based on your specific investigation. For instance, you could generate a report detailing all actions undertaken by a particular user over the previous week. While only a subset of details for each event is displayed initially, you can access additional properties in the workload-specific reports.
