Applies to

In Microsoft 365 organizations with Exchange Online mailboxes, admins can use the Submissions portal in the Microsoft 365 Defender portal to submit email messages, URLs, and attachments to Microsoft for scanning.

When you submit an email message for analysis, you will get:

  • Email authentication check: Details on whether email authentication passed or failed when it was delivered.
  • Policy hits: Information about any policies that may have allowed or blocked the incoming email into your tenant, overriding our service filter verdicts.
  • Payload reputation/detonation: Up-to-date examination of any URLs and attachments in the message.
  • Grader analysis: Review done by human graders in order to confirm whether or not messages are malicious.

Important

Payload reputation/detonation and grader analysis are not done in all tenants. Information is blocked from going outside the organization when data is not supposed to leave the tenant boundary for compliance purposes.

For other ways to submit email messages, URLs, and attachments to Microsoft, see Report messages and files to Microsoft.

Watch this short video to learn how to use admin submissions in Microsoft Defender for Office 365 to submit messages to Microsoft for evaluation.

Note

If organizations are configured to send user reported messages to the custom mailbox only, reported messages will appear in User reported messages but their results will always be empty (as they would not have been rescanned).

Undo user submissions

Once a user submits a suspicious email to the custom mailbox, the user and admin don't have an option to undo the submission. If the user would like to recover the email, it will be available for recovery in the Deleted Items or Junk Email folders.

Convert user reported messages from the custom mailbox into an admin submission

If you've configured the custom mailbox to intercept user-reported messages without sending the messages to Microsoft, you can find and send specific messages to Microsoft for analysis.

On the User reported messages tab, select a message in the list, click Submit to Microsoft for analysis, and then select one of the following values from the dropdown list:

  • Report clean

  • Report phishing

  • Report malware

  • Report spam

  • Trigger investigation

    The New options on the Action button

If the message is reported to Microsoft, the Converted to admin submission value turns from no to yes. You can directly access the admin submission by clicking View the converted admin submission from the overflow menu inside the submission flyout of the respective user reported message.
