If you receive a suspicious email and are concerned it may be a phishing attempt, you can report it using the Phish Alert Report add-in for Microsoft Outlook.
With the email open, select the ellipsis overflow menu in the email menu.
Then choose "Phish Alert Report..."
This will display the Phish Alert pane.
Click the "Phish Alert" button.
After a few moments, you should receive a Success... message.
You can close the email now.
It will be deleted and reported to the IS Security team for further investigation.
