Explanation

This query retrieves a list of MDO remediation actions via Explorer. It tracks each case with a Network Message ID and sorts the users based on the number of actions they have. The actions include Soft Delete, Hard Delete, Move to junk folder, and Move to deleted items. The query uses the EmailEvents table and filters the data for the past 30 days. It then summarizes the data by creating lists of Network Message IDs for each action type and grouping them by recipient email address. The query also calculates the number of cases for each action type and the total number of cases. Finally, the results are ordered by the total number of cases in descending order.
