Frequently Asked Questions
Why is the Catch Phish add-in visible in classic Outlook but missing in the new Outlook?
The new Outlook app utilizes a different architecture for add-ins. Sometimes, older COM add-ins are not supported, and organizations must deploy the modern web-based version of the add-in through the Microsoft 365 Admin Center for it to appear in the new interface.
How can I customize my email actions to keep the add-in visible?
In Outlook on the web or the new Outlook, go to Settings (gear icon) > Mail > Customize actions. From there, you can check the box next to your preferred security or phishing add-ins to pin them directly to the message surface.
Can I use the Catch Phish add-in on the Outlook mobile app?
Add-in availability on mobile depends on your organization's deployment settings and the specific add-in vendor. Generally, modern add-ins deployed by a Microsoft 365 administrator will also be accessible via the 'More options' (three dots) menu within an email on the Outlook mobile app.
