If the journal report decryption feature is enabled on Exchange Server 2010, then the journal reports for RMS-protected messages have two messages attached - the RMS-protected message and a clear text copy of the message. Enterprise Vault archives both copies of the message. A new advanced setting in the Exchange Journaling policy, ClearText copies of RMS Protected items, lets you select whether Enterprise Vault uses the clear text copy or the RMS-protected copy as the primary message during archiving. By default, Enterprise Vault uses the clear text copy as the primary message.

The policy setting is described in the online help in the Administration Console and in the Administrator's Guide.

If you have Enterprise Vault filters configured for Exchange Server journal archiving, it is important to understand the effect of the policy setting values, and to check that the filters work as expected before enabling filtering on your production system.
