When Office 365 quarantines a message or file sent to a Penn State user it should generate an email that looks like the image above.

This message is usually legitimate. If you do not recognize the sender mentioned in the message it is very likely that the contents referred to are malicious and should not be opened.

If you recognize the sender and when you hover over a link in the message if it does not resolve to protection.microsoft.com or a subdomain of protection.microsoft.com please do not click the link and forward the message as an attachment to phishing@psu.edu.
