The Microsoft Report Message and Report Phishing add-ins for Outlook and Outlook on the web (formerly known as Outlook Web App or OWA) makes it easy for users to report false positives and false negatives to Microsoft 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 Defender portal.
