In this article we will learn how to automatically install/roll-out the Microsoft 365 (formerly Office 365) Outlook Phish Hook add-in button to all users at once.

The Phish Hook Button add-in for Microsoft Outlook / Microsoft 365 (formerly Office 365) gives end-users the ability to report suspicious emails. The button allows your employees to take an active role in managing the problem of Phishing and other types of malicious emails. This has the benefit of providing your IT/security team with early warnings of possible phishing attacks or malicious emails, allowing them to take effective action to prevent security or network compromise.

The button will also track if your users report our simulated phishing emails, so you can see which users are successfully engaging and identifying potentially malicious emails.

NOTE: To learn how to manually install/sideload the add-in for individual users, see "Phish Hook Button - Manual Installation".

    After a few moments, you should then be met with the above screen:
  11. PLEASE NOTE the message saying it can take 12 hours for it to become available. Although the Phish Hook™ button may appear within just a few minutes, it may not be fully stable until the full 12 hours has completed. This is purely down to the Microsoft­­® architecture and our support desk will not be able to support the button before this period is completed.

Your add-ins area should now show the Phish Hook add-in:
