Add annual student attach licensing for Microsoft Dynamics 365 Customer Insights. This digital subscription provides the entitlement identified as the Student Attach annual edition, rather than a physical device, server, or separately shipped component. It applies to Customer Insights subscription environments where the required licensing designation is an annual attach offer for students. The attach designation matters when matching subscription scope. It identifies this edition as an addition associated with Dynamics 365 Customer Insights instead of a general hardware product or infrastructure component. Microsoft 3E154BCE6587-1Y specifically combines three purchasing characteristics: Customer Insights product scope, student designation, and an annual subscription term. Those details should match the intended tenant configuration before the entitlement is assigned. Customer Insights supports customer-data and engagement-related workloads within the Dynamics 365 portfolio. This subscription should be selected only when the environment requires the Student Attach edition, not merely any Customer Insights entitlement. The annual term distinguishes the subscription cadence, while the attach structure distinguishes its licensing role. No physical media, rack equipment, cabling, or endpoint hardware is associated with this software subscription.
