Add e-commerce overage coverage to a Microsoft Dynamics 365 Commerce environment using the Tier 3, Band 2 service designation. This offering is identified for education use through its STU designation and is intended for Commerce environments that require the corresponding overage classification. It is a cloud-service entitlement rather than a physical device, cable, or appliance. Microsoft part number 6553B3DCB7E9 identifies the Dynamics 365 Commerce e-commerce overage offering at the Tier 3 and Band 2 level. Those two labels are material selection details: they distinguish the applicable service tier and band within the Commerce e-commerce overage range. Match both values to the Commerce environment being administered before assigning the entitlement. This SKU differs from a base Commerce entitlement by its explicit overage role. It also carries an education-oriented STU designation, which separates it from general commercial ordering designations. The product description establishes the Commerce workload, e-commerce scope, Tier 3 classification, and Band 2 classification, while leaving licensing metrics and entitlement quantity outside the product designation.
