The Office of Information Technology will be migrating email safety and security technology to Microsoft 365 on Tuesday, June 6. This change will mostly run in the background to improve anti-spam, anti-malware and phishing protection for the CU Boulder campus, but you will start to see notifications that you haven't received before from Microsoft Defender Quarantine.

Read the OIT news story about this change, as well as the Microsoft Defender Quarantine page for additional information and instructions for releasing emails from quarantine.
