Microsoft 365

Basic information

• Model: Microsoft 365 encompasses various subscription plans tailored for personal, family, business, and enterprise use, rather than a single model. These include Microsoft 365 Personal, Family, Business Basic, Standard, Premium, Apps for Business, and Enterprise plans (E3, E5, F3, F1).
• Version: Microsoft 365 is a continuously updated service, meaning there isn't a single static version number. Updates are delivered regularly through various channels (Current Channel, Monthly Enterprise Channel, Semi-Annual Enterprise Channel) to provide new features, security updates, and non-security updates.
• Release Date: The "Microsoft 365" brand for enterprise subscriptions was first introduced in July 2017. On April 21, 2020, consumer plans of Office 365 were rebranded as Microsoft 365, expanding services to include additional security features, AI-powered insights, and better integration across devices. The predecessor, Office 365, was launched on June 28, 2011.
• Minimum Requirements:
  • Processor: 1.6 GHz or faster, 2-core (Intel processor for macOS).
  • RAM: 4 GB RAM (2 GB RAM for 32-bit Windows).
  • Storage: 4 GB available disk space for Windows; 10 GB for macOS (HFS+ or APFS format).
  • Display: 1280 x 768 resolution for Windows; 1280 x 800 for macOS.
  • Operating System: Windows 11, Windows 10, Windows Server 2016/2019/2022/2025; one of the three most recent versions of macOS; supported versions of Android and iOS.
• Supported Operating Systems: Windows (11, 10, Server 2016/2019/2022/2025), macOS (three most recent versions), Android, and iOS. Web applications are also supported across various browsers.
• Latest Stable Version: Microsoft 365 applications receive continuous updates. The specific version and build numbers vary by update channel (Current, Monthly Enterprise, Semi-Annual Enterprise). For example, the Windows stable release was the September 2025 Update (19.2509.59141.0) as of October 1, 2025.
• End of Support Date: Microsoft 365 is governed by the Modern Lifecycle Policy, requiring users to stay current with servicing and system requirements. While the service itself is continuously supported, specific components or operating system versions have end-of-support dates. For instance, Microsoft 365 Apps running on Windows 10 will receive security updates until October 10, 2028, but full support for Microsoft 365 Apps on Windows 10 ends October 14, 2025. Office 2016 and Office 2019 also reach end of support on October 14, 2025.
• End of Life Date: As a subscription-based service with continuous updates, Microsoft 365 does not have a traditional "end of life" date in the same way perpetual software licenses do. However, support for specific older operating systems or applications within the suite does end.
• License Type: Subscription-based. Licenses are available for individuals, families, small businesses, and enterprises, with varying features and user limits.
• Deployment Model: Primarily cloud-based (Software as a Service - SaaS). Desktop applications are installed on client devices, but services like Exchange, SharePoint, and OneDrive are cloud-hosted. Hybrid deployment models are also supported, allowing for integration with on-premises infrastructure. Deployment can be managed from the cloud via the Microsoft 365 portal or Microsoft Intune, or from a local source using tools like Configuration Manager or the Office Deployment Tool (ODT).

Technical Requirements

• RAM: 4 GB RAM for both Windows and macOS; 2 GB RAM for 32-bit Windows. For optimal performance in video calls and Teams live events, 4 GB RAM or higher is recommended.
• Processor: 1.6 GHz or faster, 2-core processor for Windows. An Intel processor is required for macOS. A 2.0 GHz or greater processor is recommended for Skype for Business. For Teams live events, a Core i5 Kaby Lake processor is recommended.
• Storage: 4 GB of available disk space for Windows. 10 GB of available disk space for macOS, using HFS+ or APFS hard disk format. Updates may require additional storage.
• Display: 1280 x 768 screen resolution for Windows. 1280 x 800 screen resolution for macOS. Graphics hardware acceleration requires DirectX 9 or later with WDDM 2.0 or higher for Windows 10 (or WDDM 1.3+ for Windows 10 Fall Creators Update).
• Ports: Not directly specified for the software suite itself. However, for features like video calls in Microsoft Teams or Skype for Business, a USB 2.0 video camera, microphone, and audio output device are required.
• Operating System: Windows 11, Windows 10, Windows Server 2016/2019/2022/2025, and the three most recent versions of macOS. Mobile apps support recent versions of iOS and Android.

Analysis of Technical Requirements: Microsoft 365 maintains relatively moderate technical requirements for its core applications, making it accessible on a wide range of modern devices. The emphasis on 4GB RAM and a dual-core processor reflects the need for efficient multitasking and responsiveness in productivity applications. Higher specifications are recommended for resource-intensive tasks such as video conferencing (e.g., Microsoft Teams live events), indicating that while the suite is broadly compatible, optimal performance for advanced features benefits from more robust hardware. Storage requirements are reasonable, but users should account for additional space needed for updates and local file storage. The broad operating system support across Windows, macOS, and mobile platforms ensures flexibility for users. Graphics requirements are standard for modern desktop environments, primarily for hardware acceleration. The requirements are generally aligned with typical business and personal computing setups, with specific recommendations for enhanced experiences in collaborative and multimedia-heavy scenarios.

Users always run the latest stable version available for their chosen update channel.
• OS Support: Microsoft 365 supports Windows 11, Windows 10, Windows Server (2016, 2019, 2022, 2025), and the three most recent versions of macOS. Mobile apps are compatible with recent versions of iOS (e.g., iOS 12.0 or later for Office for iPad/iPhone) and Android (ARM-based or Intel x86 processor). Web applications are supported on current and immediately previous versions of major browsers like Microsoft Edge, Chrome, Firefox, and Safari.
• End of Support Date: Microsoft 365 operates under a Modern Lifecycle Policy, meaning continuous support as long as users stay current with updates and supported operating systems. However, specific components or underlying OS versions have defined end-of-support dates. For example, Microsoft 365 Apps on Windows 10 will cease to be fully supported on October 14, 2025, though security updates will continue until October 10, 2028. Office 2016 and Office 2019 also reach end of support on October 14, 2025.
• Localization: Microsoft 365 is available in numerous languages, supporting a global user base. Specific language packs and proofing tools are available for various applications within the suite.
• Available Drivers: As a software and cloud service suite, Microsoft 365 does not typically require specific drivers for its core functionality. However, hardware components used with Microsoft 365 applications (e.g., cameras, microphones for Teams) rely on their respective device drivers provided by hardware manufacturers and supported by the operating system.

Analysis of Overall Support & Compatibility Status: Microsoft 365 demonstrates robust support and compatibility across a broad ecosystem of operating systems and devices, reflecting its role as a ubiquitous productivity platform. The subscription model ensures users consistently receive the latest features and security updates, minimizing compatibility issues with newer technologies. The Modern Lifecycle Policy, while requiring users to stay updated, provides a clear framework for long-term support. Compatibility with the latest three macOS versions and recent mobile OS versions ensures a consistent experience across personal and professional devices. The extensive localization options cater to a diverse international audience. While Microsoft 365 itself doesn't require specific drivers, its reliance on underlying operating system and hardware drivers means that maintaining up-to-date system components is crucial for optimal performance and functionality, especially for integrated communication tools like Teams. The upcoming end of support for Microsoft 365 Apps on Windows 10 in October 2025 highlights the importance of OS upgrades for continued full support.
