Exchange Online Alerts similar to OneDrive "..recently deleted a large number of.."
When I delete a large number of files in my OneDrive, SharePoint will email me saying "Heads up! We noticed that you recently deleted a large number of files from your OneDrive".
I am looking for this sort of feature, but for Exchange Online and when any user deletes a large number of items from their Deleted Items folder, the admins could be emailed with an alert.
Currently I see no settings for the Alerts in Security & Compliance for this activity.
This would help in the event someone leaves the company 'sour' and wipes their entire mailbox. Rather than waiting for an employee to look for emails and say "hey it's empty!" we could be proactive.
