Have you ever been informed that an emails has been quarantined and wondered how to view or recover it in Microsoft Outlook? Knowing how quarantined email works can definitely help you keep your communications running smoothly-especially at work, where false positives can disrupt business processes. This article will discuss how Outlook handles quarantined emails and provide clear, step-by-step instructions on how you can access and view quarantined emails in Outlook for Microsoft 365 or an Exchange account provided by an organization.
What Is an Email Quarantine and Why Does It Happen?
Email security systems provide email quarantine as a feature, which holds messages that they perceive to be harmful or suspicious before these messages actually reach your inbox. The system usually flags such quarantined messages because of one or more of the following reasons:
- It’s recognized as spam or phishing.
- It’s sent from an unknown or blocked sender.
- It contains suspicious attachments or URLs.
- It violates organizational policies.
Email quarantine is a protective layer in systems like Microsoft Defender for Office 365 or other third-party email security solutions. The primary goal is to prevent harmful messages from causing security breaches, while giving administrators (or sometimes users) the ability to review and release them manually if they’re legitimate.
Where Are Quarantined Emails Stored in Outlook?
Contrary to the belief of many users, quarantined emails do not show up in the Junk or Spam folders of Outlook. As such, the system stores them in a quarantine folder that you can access through the Microsoft 365 Security and Compliance Center or via an email notification that alerts you about the quarantined message.
Organisations may allow individual users to view or take action themselves on the items that they have quarantined. In other configurations, only IT admins can review and release quarantined emails.
How to View Quarantined Emails in Outlook via Web Panel
To view quarantined messages associated with your Outlook or Microsoft 365 account, follow these steps:
Step 1: Log in to the Microsoft 365 Security Center
- In a web browser, visit:
https://security.microsoft.com/quarantine. - Sign in with the same credentials you use for Outlook or Microsoft 365.
Step 2: Browse Your Quarantine Folder
Once logged in, you’ll see the Quarantine page showing a list of emails flagged for review.
- You can filter messages by Reason (such as Spam, Phishing, or Bulk).
- You may also see details like sender, subject, and date received.
Step 3: View Message Details
Click on any message to view more information, like the Sender, Reason for Quarantine, and Preview (if available). This helps you determine whether it’s a legitimate email or a threat.
Step 4: Take Action
If your admin allows user-level control, you’ll see options to:
- Release the email to your inbox.
- Report it as safe or unsafe.
- Block or Allow the sender (in some cases).
How to View Quarantined Emails Using Outlook’s Notification Emails
Depending on your organization’s settings, you may receive automatic quarantine summary emails, often daily or weekly.
These alert you that we have quarantined email(s) and show key details like:
- Sender
- Subject
- Time of delivery
- Block reason
You’ll usually find buttons or links like:
- Release (moves email to your inbox)
- Preview (see the email content safely)
- Block Sender (move to blocked list)
- Request Release (if admin approval is required)
Viewing Quarantined Messages in Outlook Desktop App (Admin-Level)
If you’re an IT admin managing a quarantined email for a user:
- Go to the Microsoft Defender portal.
- Navigate to the Email & Collaboration > Review > Quarantine.
- Select the quarantined message.
- Choose Message Actions, then Release Message or Allow Sender as needed.
Admins can also set policies to customize quarantine rules, set user permissions, or configure automated notifications.
Tips to Avoid Legitimate Emails Getting Quarantined
To reduce the chances of the system redirecting important emails to quarantine:
- Add trusted senders to your Safe Sender List in Outlook.
- Avoid using suspicious-looking links or heavily formatted HTML.
- Configure your company’s email domain properly with SPF, DKIM, and DMARC.
- If you’re sending bulk email (like newsletters), use reputable email service providers so they don’t flag you.
Conclusion
Quarantined emails are a way of keeping users and businesses safe from cyber threats, but being in a position to quickly access such false positives and release them is just as important as not delaying an important communication. Today, users have much greater insight and control through the Microsoft 365 Security Center or alert emails than ever before.
If you still cannot access quarantined emails or you don’t have permission to do so, contact your IT administrator, who can allow access to this email or adjust your permissions.
