In Microsoft 365 organizations with Exchange Online mailboxes and Microsoft Defender for Office 365, admins can now send templated messages back to end users after they review reported messages. This can be customized for your organization and based on your admin's verdict as well.

This feature is designed to give feedback to your users but does not change the verdicts of messages in the system. To help Microsoft update and improve its filters, you will need to submit messages for analysis using Admin submission.

You will only be able to mark and notify users of review results if the message was reported as a false positives or false negatives.

What do you need to know before you begin?

Configure the messages used to notify users

  1. In the Microsoft 365 Defender portal, go to Email & collaboration > Policies & rules > Threat policies > Others section > User reported message settings.

  2. On the User submissions page, if you want to specify the sender display name, check the box for Specify Office 365 email address to use as sender under the Email notifications for admin review results section, and enter in the name you wish to use. This is the email address that will be visible in Outlook and where replies will go to.

  3. If you want to customize any of the templates, click Customize email notification. In this flyout, you will be able to customize only the following:

    • Phishing
    • Junk
    • No threats found
    • Awareness training
    • Footer
  4. When you're finished, click Save. To clear these values, click Discard on the User submissions page.
