Have you ever received an email that was mysteriously labeled as “quarantined” by your email provider? If so, you’re not alone. Many people have encountered this perplexing situation and wondered what it means and why it happens. In this post, we will delve into the mystery of quarantined email and shed some light on this often misunderstood phenomenon.
Firstly, let’s define what a quarantined email is. A quarantined email is essentially an email that has been flagged by your email provider as potentially harmful or suspicious. This means that the email has been isolated or “quarantined” from your inbox and placed in a separate folder for further inspection. This is done to protect you from potential threats such as viruses, spam, or phishing attempts.
STEP #1:
- To open the Microsoft 365 Defender portal, go to https://security.microsoft.com.

STEP #2:
- Go to Quarantine.
- Select the email that you want to release.
Why Email Quarantines:
In Microsoft 365 organizations with mailboxes in Exchange Online or standalone Exchange Online Protection (EOP) organizations without Exchange Online mailboxes, quarantine is available to hold potentially dangerous or unwanted messages.
Whether a detected message is quarantined by default depends on the following factors:
- The protection feature that detected the message. For example, the following detections are always quarantined:
- Malware detections by anti-malware policies and Safe Attachments policies, including Built-in protection for Safe Attachments.
- High-confidence phishing detections by anti-spam policies.
- Whether you’re using the Standard and/or Strict preset security policies. The Strict profile quarantines more types of detections than the Standard profile.
In conclusion, the mystery of quarantined email is not so mysterious after all. It is a precautionary measure taken by email providers to protect users from potential threats. By understanding the reasons behind quarantined emails and following the necessary steps, we can ensure the safety and security of our email inboxes.
