Activate Auditing lets you activate additional SharePoint auditing events to improve the results of your Audit Report.
Prerequisite(s)
Your environment is a SharePoint 2010 or above on-premises farm (auditing is not supported on Microsoft 365).
You have site collection admin permissions on your targeted site collection(s).
Note: Site collection admin permissions are required even if you have higher admin privileges like Farm admin permissions. For more information, see Microsoft administrative permissions.
Tip: To manage all your site collections, you can connect to your SharePoint central admin with Farm admin permissions.
How-To
Select the item you would like to perform the action on from the Explore screen.

Select the auditing events (Note: Opening or downloading documents, viewing items in lists or viewing item properties cannot be tracked by SharePoint 2016 and Microsoft 365.)
Click Activate now (you can also schedule this task).
The task will now run.
In the case that there are warnings or errors, they will be displayed with details in separate tabs near Results.
