You can use Microsoft Outlook to recover a quarantined message from the spam quarantine mailbox. This topic provides step-by-step instructions using Outlook 2007, but you can also use Outlook 2010.

Spam quarantine is a feature of the Content Filter agent that reduces the risk of losing legitimate messages. Spam quarantine provides a temporary storage location for messages that are identified as spam and that shouldn't be delivered to a user mailbox inside the organization. When a message meets the spam quarantine threshold, it's wrapped in a non-delivery report (NDR) and delivered to the spam quarantine mailbox. For more information about the spam quarantine feature, see Understanding Spam Quarantine.

  • A spam quarantine mailbox is configured. For more information, see Specify a Spam Quarantine Mailbox.

  • You have been granted owner rights to the spam quarantine mailbox.

Use Outlook 2007 to release a message from the spam quarantine mailbox

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Mailbox access" entry in the Transport Permissions topic.

Any quarantined messages will be stored as NDRs in the Inbox folder of your quarantine mailbox. To access the quarantine mailbox, you need to configure an Outlook profile for that mailbox and then open the mailbox using Outlook. For more information about configuring and using multiple Outlook profiles, see Overview of Outlook e-mail profiles.

  1. Log on to the quarantine mailbox using Outlook 2007 on a client computer.

  2. In the Mail Folders list, select the Inbox folder.

  3. Find the NDR of the message that you want to recover, and then double-click the NDR to open it.

  4. On the Report tab, in the Respond group, click Send Again.

  5. When the e-mail message opens, click Send to resend the e-mail message to the intended recipient.

Other Tasks

Because the quarantined messages are stored as NDRs in the quarantine mailbox, the postmaster address of your organization will be listed as the From: address for all messages. To make it easier to locate the message you want to recover, you can create a custom Outlook form and modify the default view to expose the original sender address in the list of messages. For detailed steps, see Configure Outlook to Expose Original Sender Field in the Quarantine Mailbox.
