How to Add Access to the Office 365 EOP Quarantine in Outlook and OWA

Monday, February 16, 2015
Exchange Online Protection (EOP) in Office 365 offers a quarantine feature for administrators and end-users. Administrators can view and release messages that were caught as spam for all users. End-users can view and release their own messages.

The administrative quarantine is accessed from the Office 365 Exchange Admin Center > Protection > Quarantine. Here you will see all the quarantined items for all users in the org.

The administrative quarantine is always available to EOP admins. The end user quarantine must be enabled and configured by the admin from Office 365 Exchange Admin Center > Protection > Content Filter, then click the Configure end-user spam notifications link on the right.

When enabled, end-users will receive an email from EOP listing all the new messages held in quarantine since the last notification.

That's all pretty cool, but wouldn't it be nice to access the quarantine directly from Outlook? Here's how you configure it:

  • Open Outlook as the end-user.
  • Right-click the user mailbox and select New Folder.
  • Name the folder Quarantine or * Quarantine to have it placed higher in the folder list.
  • Right-click the new folder and select Properties.
  • Click the Home Page tab.
  • Enter in the Address field and then click the checkbox for Show home page by default for this folder. Click OK.
  • You will then see the sign on page for EOP within Outlook. After you sign in you can access your end-user archive.

Unfortunately you can't view the end-user quarantine using this method from OWA, but I have a work-around. 
  • Send yourself an email with the subject of Quarantine and the link to in the body of the message.
  • Drag the message from your Inbox to the Quarantine folder you created.
Now you have easy access to the end-user Quarantine from Outlook, OWA, and even mobile devices!
