To enable this, go to Audit Log Search page in Security and Compliance center -> Search & Investigation and click on Start recording user and admin activity. This is a one-time action to perform..
 
   
2. If the link is not available it means that auditing is already enabled in your tenant. After enabling, a message will be shown that the audit log is being prepared and that you can run a search in a couple of hours after the preparation is complete.
