In which of the following scenarios would a routing rule be applied?

Routing rules in Dynamics 365 Customer Service are designed to streamline the process of assigning cases to the appropriate agents or teams based on predefined criteria. The correct scenario for the application of a routing rule is when a case is created by a record creation rule. This is because record creation rules can trigger actions, such as generating cases from emails or other sources, and at that point, the routing rules will evaluate the new case and determine how it should be routed.

In this scenario, when a case is automatically generated through a record creation rule, the system applies the routing rules without any manual intervention, ensuring that cases are handled by the right personnel efficiently. This speeds up response times and enhances service delivery.

While other scenarios involve agent actions such as creating cases manually, saving, or adding to a queue, routing rules do not come into play in those instances. They specifically target situations where cases are created automatically, enabling seamless operations within the customer service process.
