Add student-focused access to Dynamics 365 Business Central Essentials through an attach entitlement for education environments. The product name combines three important selection details: it applies to the Essentials edition, it is intended for students, and it uses an attach licensing structure. Those details matter when aligning the entitlement with an existing Business Central Essentials environment. Microsoft 89C1EFC429CA is positioned for institutions that need student access associated with their Business Central deployment. An attach entitlement differs from a separately described standalone offer because it is intended to be associated with an existing eligible base environment. The Essentials designation is also significant: it identifies the Business Central product edition named by this entitlement rather than a general Microsoft application license. Use this subscription where student users require Business Central Essentials access for coursework, training, or institution-managed learning environments. Review the existing tenant, licensing eligibility, and student-user requirements before assignment so the attach structure aligns with the intended environment. The product title does not establish a subscription duration, user quantity, geographic scope, or included support services, so those factors should be selected separately where required.
