The quarantine contains all inbound and outbound email that is classified as either spam or malware by the system. You can search for quarantined emails based on various filters. Messages are automatically deleted after the 30 days in quarantine.

The Quarantine page displays information about each quarantined email:

From
Recipients
Subject
Email server (originating)
Reason it was flagged as malicious (Policy Action - PA, Spam - S, Virus - V, and Advanced Threats - AT)
A green icon in a category indicates that the email was not considered malicious for that specific category. A red icon indicates that it was malicious. A gray icon indicates that the email analysis was not performed.
Age (the amount of time the email has been in the quarantine)
The last column will display a paper airplane if the email is still in quarantine but is marked to be released. Once the email is released, the airplane disappears.
