Using PhishHuk
PhishHuk is a Microsoft Office 365 plug-in that enables users to report suspicious emails for further analysis from within the Outlook client itself via mobile, desktop, and browsers. This means that you can pursue a more integrated approach in how you respond to possible phishing emails.
When a user reports an email, your internal network and security team is immediately notified, and they can decide what actions to take. A notification is also sent to the user.
