SYMPTOMS
When a user clicks Reply to All in an e-mail message in a Microsoft Exchange Server 2003 organization, no intended recipients receive a reply. Additionally, no non-delivery report (NDR), error message, or event is generated to indicate that the message was not delivered.

<div class="cause_section">

CAUSE
This problem can occur when a user clicks Reply to all in an e-mail message, and a recipient is included whose e-mail address is malformed. For example, the e-mail address for one of the intended recipients may contain a mismatched delimiter, such as only one of the following pairs of delimiters:
 * &quot; &quot;
 * [ ]
 * [ ]

In this event, the message is not delivered to any intended recipients. Here is an example of a malformed e-mail address that contains a mismatch that uses only the &quot;>&quot; delimiter without the &quot;<&quot; delimiter: &quot;recipient>someone@example.com.&quot;
