When a user clicks "Reply to All," no intended recipients receive a reply in Exchange Server 2003 (900719)

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:

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 ">" delimiter without the "<" delimiter: "recipient>someone@example.com."
