Email message and NDR message are not delivered if an email message contains unsupported character sets in an Exchange Server 2010 environment

Consider the following scenario:
  • You apply Update Rollup 4 for Exchange Server 2010 Service Pack 1 (SP1) in a Microsoft Exchange Server 2010 environment.
  • You create a journaling mailbox.
  • An email message is sent to a journal recipient. The email message contains unsupported character sets, such as the ISO-2022-JP-2 character set.
In this scenario, the email message and the non-delivery report (NDR) message remain in the delivery queue on the Exchange Server 2010 Hub Transport server. Additionally, you receive the following error message in the Queue Viewer tool:
400 4.4.7 The server responded with: 550 5.6.0 CAT.InvalidContent.Exception: InvalidCharsetException

You receive the error message if one of the following conditions is true:
  • You create a journal rule to enable journaling for the email messages that are sent to the journal recipient. The rule sends journal reports to the journaling mailbox.
  • You configure the journaling mailbox to forward email messages to another mailbox.

This issue occurs because the Exchange server generates a new message for forwarding which does not inherit a certain property from the original message. Therefore, the Exchange server does not process the message.
To resolve this issue, install the following update rollup:
