Before configuring the PartnerExpress server, you have to set up the trading participants. For more information, see TIBCO BusinessConnect™ Services Plug-in User’s Guide, Chapter 6, "Setting Up Trading Hosts and Partners" or
TIBCO BusinessConnect™ EDI Protocol powered by Instream User’s Guide, Chapter 3, in the section "Setting Up Trading Partners."
By default, the two properties are set to 1440 minutes, which means that after the Notify or Response transaction payload resides in Inbox for 1440 minutes, it is deleted. But you can also specify the timeout values in TIBCO Administrator by clicking
BusinessConnect > System Settings > Activated Protocol Plug-ins and Properties > BC > Inbox Transport Settings.
