For example, suppose that people are reporting many messages using the Report Phishing add-in. Microsoft uses these submissions to improve the effectiveness of email protection technologies. The Report Message and Report Phishing add-ins for Outlook and Outlook on the web (formerly known as Outlook Web App) enable people to easily report false positives (good email marked as bad) or false negatives (bad email allowed) to Microsoft and its affiliates for analysis.
For more information, see Use Admin Submission to submit suspected spam, phish, URLs, and files to Microsoft. If you're an admin in a Microsoft 365 organization with Exchange Online mailboxes, we recommend that you use the Submissions page in the Microsoft 365 Defender portal.
