Email quarantine

Email Quarantine is a feature in Microsoft Defender (part of Microsoft 365) that automatically prevents email messages that have a high probability of being spam, phishing, or malware from going into your mailbox.

These messages will be held in ‘Quarantine’ for 30 days.

This safeguards you and the McMaster community by preventing potentially harmful messages from reaching your inbox, where accidental clicks or responses could expose you to phishing or malware attacks.
