In Microsoft 365 organizations with mailboxes in Exchange Online, users can report phishing and suspicious email in Outlook. Users can report false positives (good email that was blocked or sent to their Junk Email folder) and false negatives (unwanted email or phishing that was delivered to their Inbox) from Outlook on all platforms using free tools from Microsoft.

Microsoft provides the following tools for users to report good and bad messages:

• Built-in reporting in Outlook on the web (formerly known as Outlook Web App or OWA).
• The Microsoft Report Message or Report Phishing add-ins. The add-ins work on virtually all Outlook platforms, including Outlook on the web. For more information, see Enable the Microsoft Report Message or Report Phishing add-ins.

For more information about reporting messages to Microsoft, see Report messages and files to Microsoft.

Admins configure user reported messages to go to a specified reporting mailbox, to Microsoft, or both. These user reported messages are available on the User reported tab on the Submissions page in the Microsoft Defender portal. For more information, see User reported settings.

Review reported messages

To review messages that users have reported to Microsoft, admins can use the User reported tab on the Submissions page in the Microsoft Defender portal at https://security.microsoft.com/reportsubmission. For more information, see View user reported messages to Microsoft.

Note

If the User reported settings in the organization send user reported messages (email and Microsoft Teams) to Microsoft (exclusively or in addition to the reporting mailbox), we do the same checks as when admins submit messages to Microsoft for analysis from the Submissions page. So, submitting or resubmitting messages to Microsoft is useful to admins only for messages that have never been submitted to Microsoft, or when you disagree with the original verdict.
