DOCUMENT:Q278352 08-MAY-2002 [exchange] TITLE :XWEB: Can't Forward Autoforwarded Messages to External Address PRODUCT :Microsoft Exchange PROD/VER::5.5 OPER/SYS: KEYWORDS:exc55 kbExchange550preSP5fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- SYMPTOMS ======== When you use Microsoft Outlook Web Access (OWA) to forward or reply to a message and the message travels over an Internet Mail Service connector, the message may not arrive at the destination address. You also may not receive a non-delivery report (NDR). The following message may be logged in the Application event log on the Internet Mail Service computer: Event ID: 4123 Source: MSExchangeIMC Description: A message passing through the Internet Mail Service has been intentionally dropped. This is most likely an admin notification (message describing mail failure) and out of office notification (OOF), or an automatic reply from a user's mailbox. Dropping of OOF messages and automatic replies is configurable in the admin pages. The gateway must always drop notification to the administrator, since they often cause mail loops. CAUSE ===== This problem can occur because, by default, the Internet Mail Service is set not to allow autoforwarded messages to external addresses. When OWA forwards or replies to a message that was autoforwarded, OWA leaves a field on the message of PR_Auto_Forwarded. The Internet Mail Service detects the PR_Auto_Forwarded field and does not let the message through.
