The information in this article applies to:

 - Microsoft Exchange Server, version 5.5

SYMPTOMS

When users and administrators send messages that have three or more attached
files through two Microsoft Mail Connectors, a non-delivery report (NDR) will be
sent to the postmaster with the following message:

   MS Mail Connector failed parsing the message content.

This occurs because the attachment tags are not being parsed correctly.
