Best Practices

) Confirm that Active Directory is properly configured so email senders have a manager to approve or reject quarantined emails.

Microsoft Exchange Active Directory is required to assign a manager to a sender. You can create a transport rule to quarantine and send the email for approval by the sender's manager. To successfully quarantine a sender's email if sensitive data is detected by

Enterprise DLP

, a sender must have a manager assigned.

If no manager is assigned to a user, then the quarantined email is sent to the recipient because no manager is assigned to approve or reject the email.

Best Practices
