DOCUMENT:Q259881 01-JUN-2001 [exchange] TITLE :XADM: EventID 2078 Occurs When Client Has Multiple Transport PRODUCT :Microsoft Exchange PROD/VER:winnt:5.5 SP3 OPER/SYS: KEYWORDS:exc55sp3 kbExchange550preSP4fix kbExchange550sp4Fix kbgraphxlinkcritical ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 SP3 ------------------------------------------------------------------------------- SYMPTOMS ======== When you send an Internet e-mail message under the following conditions - Exchange Server 5.5 Service Pack 3 is installed on the server. - Either Microsoft Exchange Client or Microsoft Outlook has the two following transport providers on the client: - The Microsoft Exchange Transport provider. - The Internet Mail Service provider. - The Internet Mail Service is set first in the order of transports. - The Exchange Server recipient is set in the To or Cc box of the e-mail message and the Internet recipient is set in the Bcc box of the e-mail message. -or- The Exchange Server recipient is set in the Bcc field of the e-mail message and the Internet recipient is set in the To or Cc box of the e-mail message. the following event is logged in the application event log: Event ID: 2078 Source: MSExchangeIS Private Type: Error Category: Transport Sending Unable to submit, send, or transfer out a message. Check PR_RESPONSIBILITY. Nevertheless, the message is sent without any issues. CAUSE ===== This issue is caused by the Information Store service in Exchange Server 5.5 Service Pack 3. PR_RESPONSIBILITY, as described in the error message event in the "Symptoms" section of this article, is a property of the recipient and is set to True by default. After the e-mail message is sent by each provider, the PR_RESPONSIBILITY property of the recipients who have been transmitted is set to False by each transport provider. The Event ID 2078 error message indicates that all PR_RESPONSIBILITY properties of recipients are set to False, so no recipient exists to send a message. When the Exchange Transport provider delivers the message to the Information Store service after it sends to the SMTP recipient by using the Internet Mail Service provider, the PR_RESPONSIBILITY property of the SMTP recipient is set to False. Therefore, the Exchange Server service provider delivers one message with the following conditions: - The PR_RESPONSIBILITY property of the SMTP recipient in the To or Cc box is set False. - The PR_RESPONSIBILITY property of the Exchange Server recipient in the Bcc box is set True. In Exchange Server 5.5 Service Pack 3, the fix described in the following article separates the Bcc and To or Cc box transports: Q235455 XCON: Modification in X.400 Blind Copy Implementation Event ID 2078 occurs when the Exchange Server recipient is not included in either the To or Cc recipients or the Bcc recipients.
