This new security feature delivers suspicious emails, such as those with harmful links or potential phishing attempts, to a secure quarantine area instead of your inbox.
A daily summary will now be delivered to your inbox, informing you of any quarantined messages. This will be sent from quarantine@messaging.microsoft.com.
Accessing your quarantined messages
Clicking the 'Quarantine page' link will take you to the Microsoft quarantine portal within the Security Center, where you can review and, potentially, based on the email classification, release emails if necessary.
Reviewing your quarantined messages
Be cautious when releasing emails from this location, as quarantined emails may contain spam or phishing attempts.
Releasing an email from quarantine doesn’t stop similar messages from being quarantined in the future. To help the system learn, you may need to mark them as ‘Not Junk’ or ‘Not Phishing’ more than once. In addition, you can ‘Allow Sender’ from the flyout on the right when you select the email you wish to release.
