Explanation

This query is looking at office activity data. It's specifically searching for operations that include either "Remove" or "Disable" and match certain keywords related to security features (AntiPhish, SafeAttachment, SafeLinks, Dlp, Audit). It's then extracting IP address and port information from the ClientIP field. The final output of the query will show the time the activity was generated, the office workload, record type, user type, user ID, IP address, operation, result status, and parameters.
