1. Sign in to the Microsoft 365 Security & Compliance Center with your admin credentials.
2. Navigate to Search > Audit log search.
3. Under Activities, select the activities you want to track, such as FileAccessed or FileAccessFailed. You can also use the search bar to filter specific activities.
4. Set the time range for the search. You can search for activities that occurred in the last 7, 30, 90, or 180 days, or set a custom time range.
5. Under Users, select the users you want to include in the search.
6. Under File, select the specific SharePoint Online site or Microsoft Teams team you want to track.
7. Click Search to start the search.

The search results will show you the activities that match your search criteria, along with details such as the user who performed the activity, the date and time it occurred, and the file or folder that was accessed. You can export the search results to a CSV file for further analysis or reporting.
