In Exchange Server 2007, messages delivered to the quarantine mailbox show up as DSNs sent by the postmaster address of the default domain. In HOW TO: Expose original senders and recipients of quarantined messages, we modified the QTNE.cfg form for Microsoft Outlook to reveal original senders and recipients.
Although the original sender and recipient fields were added, the original SCL stamped on the quarantined message wasn’t visible. The OriginalScl property was exposed in Exchange 2007 SP1, and is now included in the updated form in that post. Installing the updated form exposes the original SCL for messages in the quarantine mailbox, as seen in Figure 1.
