The Microsoft Report Message and Report Phishing add-ins for Outlook and Outlook on the web (OWA) makes it easy for users to report false positives and false negatives for analysis. False positives are good email that was blocked or sent to the Junk Email folder. False negatives are unwanted email or phishing that was delivered to the Inbox.

The Report Message add-in provides the option to report both spam and phishing messages. The Report Phishing add-in provides the option to report phishing messages only.
