SYMPTOMS

In a Microsoft Exchange Server 2007 environment, a user sends an e-mail message that has an attachment. Additionally, this e-mail message has no text in the body of the e-mail message. However, when a user receives the e-mail message, the attachment incorrectly appears as the body of the e-mail message. The original e-mail message may have content that resembles the following:

From: somebody_sender@example.com
Subject: Test message
To: somebody_receiver@example.com
MIME-Version: 1.0
Content-Type: text/plain; name="test_attach.txt"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="test_attach.txt"

CAUSE

This problem occurs because Exchange Server 2007 ignores the part of the original e-mail message that contains "Content-Disposition: attachment." Therefore, the message is processed incorrectly, and the attachment appears as the body of the e-mail message.
