Microsoft Exchange Server 2019 Enterpriseは、Microsoftのオンプレミスメールプラットフォームの最高容量エディションであり、サーバーあたり最大のデータベース密度を必要とする大規模組織、ホスティングプロバイダー、マルチテナント環境向けに設計されています。EnterpriseエディションはStandardと同じコードベースと機能を共有しますが、データベースマウント制限が撤廃され、サーバーあたり最大100個のマウント済みデータベースをサポートします（Standardは5データベース制限）。
ジャーナリングは、規制アーカイブのためにすべてのメール通信の完全なコピーをキャプチャします。インプレースアーカイブは、ユーザーに古いメッセージ用のオンラインアーカイブメールボックスを提供し、プライマリメールボックスのサイズを削減しながら、過去のメールを検索可能でアクセス可能に保ちます。Information Rights Management（IRM）は、機密メッセージの不正な転送、コピー、印刷を防止します。
Enterpriseエディションはサーバー単位でライセンスされ、アクセスするユーザーまたはデバイスごとにExchange Server CAL（StandardまたはEnterprise）が必要です。複数のデータベースを持つ組織や、Enterprise CALを通じてエンタープライズコンプライアンス機能を必要とする組織にとって、このエディションはミッションクリティカルなメールインフラに求められる規模と機能を提供します。
