If you configure this response rule to perform the Archive and classify message action, you also specify the retention category that Enterprise Vault should apply to the archived message. The list of available retention categories that is shown in the Enforce Server administration console is defined using a configuration file, RetentionCategories.config.

If you change the retention categories that are available in an Enterprise Vault deployment, you should also manually change the available categories that are defined in RetentionCategories.config.
