Shared queues contain outbound messages for data that is dynamic shared or bulk shared out of your ServiceNow instance. Subscribed queues contain inbound messages for data coming into an application instance or database. A default subscribed queue is also created in your ServiceNow instance when you install DataSync for ServiceNow.
To configure your shared queues and subscribed queues in ServiceNow, you will need to input your Perspectium Integration Mesh (MBS) login information.
