Add Project Operations licensing to an eligible Microsoft cloud environment with a 36-month attach subscription. Dynamics 365 Project Operations supports organizations running project-based work where project teams need a dedicated application entitlement within their existing Microsoft business application environment. Microsoft EC623AA99BF2 identifies the attach offer and its stated 36-month subscription duration. Attach licensing is intended for tenants that already hold the qualifying subscription required by Microsoft for this offer. It is not a server, appliance, downloadable media package, or physical device. The entitlement is administered in the customer’s Microsoft cloud tenant, making it appropriate where user access to Project Operations must be added under the applicable Microsoft subscription structure. The defining characteristics of this offer are its Project Operations attach designation and fixed 36-month term. Those details matter when matching the subscription to an existing environment: the attach status determines the prerequisite licensing relationship, while the term establishes the subscription period. Confirm that the intended tenant and assigned users meet Microsoft eligibility requirements before assigning the entitlement.
