Manage organizational email through Mimecast Unified Email Management Express under an annual subscription term. This entitlement is for the Express service offering and is not a physical security appliance, server, gateway, or software media product. It fits deployments that consume Mimecast email services through the provider platform and need a subscription associated with the Unified Email Management Express designation. M_MAIN-UEMEXP_15_M provides the annual subscription product for that service. The ordering code matters when matching an existing Mimecast service requirement because subscription offerings can differ by service designation and term. Use this code where Unified Email Management Express is the specified service, rather than selecting a generic email-security product or an unrelated Mimecast entitlement. For email environments, the relevant deployment context is the organization’s Mimecast tenant and its email-management requirements, not rack space, power, ports, or endpoint hardware compatibility. The annual term makes this product suitable for maintaining access to the named Express offering across a defined subscription period. Confirm the required service designation and entitlement scope within the organization’s Mimecast environment before assignment, particularly when the tenant contains multiple email-management services or subscription terms.
