The recipient does not receive an attachment when an RTF e-mail message is delivered though an Exchange Server 2003 bridgehead server (901035)

SYMPTOMS

Consider the following scenario. You send a Rich Text Format (RTF) e-mail message that includes an attachment. This e-mail message is delivered to the recipient through a Microsoft Exchange Server 2003 bridgehead server.

In this situation, one of the following symptoms may occur:

The recipient does not receive the attachment when the e-mail is delivered.
The e-mail message is received in plain text format instead of in the expected RTF.

Note You do not experience this problem in Microsoft Exchange Server version 5.5.

CAUSE

This problem occurs because Exchange Server 2003 cannot handle the additional space that is in the X-MS-TNEF-Correlator field in the e-mail message. Therefore, Exchange Server 2003 cannot obtain the value of the X-MS-TNEF-Correlator field from the PR_TNEF_CORRELATION_KEY property. The PR_TNEF_CORRELATION_KEY property is encapsulated from the TNEF part of the e-mail message body.

If Exchange Server 2003 cannot obtain the value of the X-MS-TNEF-Correlator field from the PR_TNEF_CORRELATION_KEY property, the program drops the attachment of the RTF e-mail message.
