Reporting a Phishing Email (Updated)
In a recent update, the phish button was moved to a new location in outlook. To report a phishing email, you'll need to click the app icon in the top right corner of the message (the icon looks like a waffle)
Once you click that, you will see the familiar phish button.
Once you click it, a side window will open with details about the email and you'll just need to click the bottom button to report it.
