The Microsoft Report Message and Report Phishing add-ins for Outlook and inbuild report button on Outlook on the web (formerly known as Outlook Web App or OWA), new Outlook for Windows, legacy Outlook for Windows makes it easy for users to report false positives and false negatives to Microsoft 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.
Microsoft uses these user-reported messages to improve the effectiveness of email protection technologies. For example, suppose that people are reporting many messages using the Report Phishing add-in. This information surfaces in the Security Dashboard and other reports. Your organization's security team can use this information as an indication that anti-phishing policies might need to be updated.
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.
Admins can install and enable the add-ins for the organization. Both add-ins are available through Centralized Deployment. Individual users can install the add-ins for themselves.
After the add-in is installed and enabled, users see the following icons based on their Outlook client:

Important * Microsoft recommends that you use roles with the fewest permissions. Using lower permissioned accounts helps improve security for your organization. Global Administrator is a highly privileged role that should be limited to emergency scenarios when you can't use an existing role.
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.
