Which app is designed for external customers to view the progress of their service cases?

The Power Apps Portal is specifically designed to enable external users, such as customers, to access and interact with data and services. In the context of service cases, the portal allows customers to log in and view the status of their inquiries or service requests. This functionality empowers users to have transparency and control over their service experience, making it a suitable option for organizations looking to improve engagement and communication with their customers.

Power BI, while a powerful tool for data visualization and reporting, is intended for business intelligence purposes and is not designed for customer-facing interactions. It focuses on internal data analysis rather than providing case-specific information to external customers.

Power Automate primarily serves to automate workflows between applications and services, streamlining processes, which can indirectly support service case management but does not provide a direct interface for external customers to view case statuses.

Dynamics 365 Customer Service is designed to manage customer service operations, providing tools for agents to assist customers. However, it does not specifically cater to an external audience for case progress visibility in the same way that Power Apps Portal does, which is tailored for customer engagement and visibility into their service requests.
