Microsoft 365 E5 (Enterprise subscription)

Microsoft 365 E5 (AAA-10755) is Microsoft's highest-tier commercial productivity and security subscription, designed for large enterprises requiring a unified platform spanning collaboration, advanced threat protection, compliance automation, and analytics. Built on the Microsoft 365 cloud architecture, E5 integrates Microsoft Teams, Exchange Online Plan 2, SharePoint Online Plan 2, and OneDrive for Business Plan 2 with full-suite desktop applications across Windows and macOS. The subscription incorporates Microsoft Entra ID Plan 2 (formerly Azure Active Directory Premium P2) for identity governance, Privileged Identity Management, and risk-based Conditional Access, establishing a zero-trust security foundation across the enterprise estate.

The E5 tier uniquely consolidates three otherwise separately licensed security pillars: Microsoft Defender for Endpoint Plan 2, Microsoft Defender for Office 365 Plan 2, and Microsoft Defender for Identity — alongside Microsoft Sentinel-ready data connectors and Microsoft Defender for Cloud Apps (formerly Cloud App Security). Compliance capabilities include Microsoft Purview Information Protection, eDiscovery Premium, Communication Compliance, Insider Risk Management, and Customer Lockbox, making E5 the appropriate selection for organisations subject to rigorous regulatory frameworks such as HIPAA, FedRAMP, ISO 27001, and GDPR. Microsoft Purview Audit (Premium) provides high-bandwidth audit log access with extended 180-day default retention expandable to ten years.

As the qualifying base license for Microsoft 365 Copilot add-on eligibility in 2026 enterprise deployments, E5 subscribers can extend the platform with AI-assisted productivity across Word, Excel, PowerPoint, Outlook, Teams, and Loop without requiring additional foundational license upgrades. The subscription is licensed on a per-user, per-month basis under a minimum 12-month Enterprise Agreement commitment, supporting up to five concurrent device installations of Microsoft 365 Apps for Enterprise and covering mobile platforms including iOS and Android through Intune-managed app protection policies.
