From Tuesday 27 January, Microsoft Quarantine will be introduced to keep our emails secure and protect our University community from phishing, malware and spam threats.

This update is part of our ongoing commitment to safeguarding sensitive information and ensuring a secure digital environment for our students and colleagues at Westminster.
What is Microsoft Quarantine?
Microsoft Quarantine is a feature within Microsoft 365 that automatically isolates suspicious or potentially harmful emails before they reach your inbox. These messages are held in a secure location where you can review, release or report them to [email protected].
When a message has been flagged as ‘risky’, you will receive a quarantine notification email from [email protected]. The notification will include links to review and take action on quarantined messages.
Messages remain in quarantine for 30 days, after which they are automatically deleted. You can access the quarantine portal at any time via the Microsoft Quarantine Portal.
Key benefits of Microsoft Quarantine:
- Enhanced protection: provides an extra layer of defence against phishing, spoofing, and malware attacks by preventing risky emails from reaching your inbox.
- User empowerment: you can manage your own quarantined messages, including releasing legitimate emails and blocking unwanted senders.
- Compliance: Quarantine supports our security policies and helps ensure compliance with data protection standards.
How can you manage quarantined messages?
While Microsoft Quarantine and SafeLinks enhances protection against malicious threats, staying vigilant and being able to identify phishing emails remains essential.
If you suspect you have received a phishing or scam email, please report any suspicious activity to us.
