Platform configuration Preview output connector configuration When displaying documents in web applications, preview output connectors are used. If certain prerequisites are fulfilled, you can use default preview connectors, which are automatically created and selected at preview service requests. If the prerequisites are not fulfilled, you must manually create and select the preview connectors. Message storage configuration Paused Messages are stored in the Message storage in the runtime repository. To enable use of this storage, you must make sure that input and output queues are used in the Design Center Project. When a final document is distributed, the corresponding Message remains in the Message storage until an expiry time has elapsed. You enable and configure the expiry time in the Platform configuration.
