In Microsoft 365 organizations with Exchange Online mailboxes and Microsoft Defender for Office 365, admins can send templated result messages back to users after they review the user reported messages. Admins can customize the notification message template that's used for the organization.

The feature is designed to give feedback to users without changing the message verdicts in the system. To help Microsoft update and improve its filters, admins need to submit user reported messages to Microsoft for analysis when the user reported settings are configured to send user reported messages to the reporting mailbox only. For more information, see User reported settings.

Admins can mark messages and notify users of review results only if the user reported the message as a false positive or a false negative.
