SYMPTOMS
========

When you send mail to an X.400 personal address book (PAB) entry or one-off
address, you may receive the following non-delivery report (NDR):

  The following recipient(s) could not be reached:

     'Recipient' on 10/16/97 8:13 AM
           Unable to deliver the message due to a recipient problem
           MSEXCH:MSExchangeIS:SiteName:ServerName

In addition, the following event will be logged in the application log of the
Microsoft Exchange Server computer:

  Event ID: 3150
  Source: MSExchangeMTA
  Type: Warning
  Category: X400 Service

  Description:
  An internal MTA error occurred. Object 06000056 failed integrity
  verification. DB attribute: 0. OM attribute: 0. Entity name:

  /o=Organization/ou=SiteName/cn=Configuration/cn=Servers/cn=Servername/cn
  =Organization Private MDB. [XAPI  APPLICATION 31 130 (14)

The object ID referenced in the event description will vary.

CAUSE
=====

The target X.400 address does not have a value for Surname(s). According to the
X.400 specification, a surname is required for an X.400 address to be valid.

RESOLUTION
==========

To resolve this problem, add a surname to the PAB entry or one-off address.
