Microsoft Exchange Server 2019 Enterprise License Key

Buy Microsoft Exchange Server 2019 Enterprise from €99.00 — a genuine perpetual license with instant digital delivery. The premium edition of Microsoft's on-premises email and collaboration platform, designed for large enterprises that need to support more than 5 mailbox databases per server, high-availability DAG deployments, and complete control over their messaging infrastructure — without cloud dependency or recurring Microsoft 365 subscription costs.

What Is Exchange Server 2019 Enterprise?

Microsoft Exchange Server 2019 Enterprise is the full-featured edition of Exchange 2019, offering unlimited mailbox databases per server (up to 100), advanced Database Availability Group (DAG) support, and the highest possible messaging SLA for large organisations. It's the ideal choice for enterprises requiring on-premises email sovereignty, regulatory compliance (GDPR, HIPAA), or integration with hybrid Microsoft 365 environments — all while keeping messaging data under full organisational control.

Key Features of Exchange Server 2019 Enterprise

• Up to 100 Mailbox Databases per Server: Enterprise edition removes the Standard 5-database limit — essential for large-scale deployments with thousands of mailboxes
• Database Availability Groups (DAGs): Automatic mailbox replication across up to 16 servers for high availability and zero-downtime failover
• Improved Security Architecture: MetaCache Database (MCDB) for NVMe SSDs dramatically improves I/O performance; built-in certificate management
• Hybrid Deployment with Microsoft 365: Seamlessly migrate mailboxes between on-premises and Exchange Online, maintain a unified Global Address List
• Enhanced Anti-Malware and Anti-Spam: Multi-engine malware scanning and connection filtering built into Exchange Transport
• Modern Authentication Support: OAuth 2.0 and certificate-based authentication for Outlook and mobile clients
• Data Loss Prevention (DLP): Policy-based controls to prevent sensitive data from leaving the organisation
• In-Place Archiving and eDiscovery: Compliance archiving, litigation hold, and content search for regulatory requirements
• Outlook on the Web (OWA): Modern, responsive web mail client accessible from any browser or device
• Supports Windows Server 2019/2022: Built for the latest Windows Server platforms with full Hyper-V compatibility

Frequently Asked Questions

Is Exchange Server 2019 still a good choice vs Microsoft 365?
Yes, for many organisations. Exchange 2019 gives you complete data sovereignty, no per-user subscription costs, compliance control, and independence from Microsoft's cloud infrastructure. For organisations with compliance requirements or strict data residency needs, on-premises Exchange remains the preferred solution.

Do I need CALs in addition to this server license?
Yes. Each user or device accessing Exchange requires an Exchange Server Enterprise CAL (or Standard CAL for basic features). Contact us for CAL licensing guidance.

What Windows Server version do I need?
Exchange Server 2019 requires Windows Server 2019 or Windows Server 2022. See our Server 2022 Standard or Server 2019 Standard listings for low-cost genuine keys.

Is extended support available for Exchange 2019?
Yes. Microsoft Exchange Server 2019 mainstream support runs until January 2024, with extended support continuing until October 14, 2025. ESUs may be available after that date.
