Exchange Enterprise CAL Services
Every Exchange Enterprise CAL Services part number on Microsoft’s current Open Value price list — 1 license type across Corporate, Government, priced at Microsoft ERP. Open Value buys perpetual licenses (with or without Software Assurance) under an agreement, with payments spreadable across the term — still the right door for organizations mid-agreement or buying products that never moved to CSP.
Exchange Online
Most organizations now run this workload in Microsoft 365 — Exchange Online replaces on-premises Exchange for the typical case, with no server to license or patch.
