Each user gains the full desktop and mobile Office experience, a 100 GB business-class mailbox, and unlimited personal cloud storage, while your administrators enforce policies that protect your intellectual property. It is the definitive productivity solution for the modern, security-conscious business.

Key features and benefits

• Always up-to-date Office applications – Install the full desktop versions of Word, Excel, PowerPoint, Outlook, and more on up to 5 PCs or Macs, 5 tablets, and 5 smartphones per user. Your team always works with the latest features and security patches, eliminating version fragmentation.
• Enterprise-grade email and calendaring – Each user receives a 100 GB Exchange Online mailbox with hosted voicemail and advanced anti-malware protection. In-Place Archiving and litigation hold ensure critical communications are preserved and discoverable.
• Unlimited personal cloud storage – OneDrive for Business provides 1 TB of storage per user initially, expandable to unlimited, with robust sync clients for Windows and macOS. Users can access, share, and co-author files from anywhere, on any device.
• Intelligent collaboration with Microsoft Teams – Persistent chat, online meetings, and deep integration with Office apps create a hub for teamwork. Replace fragmented communication tools with a single, secure platform.
• Advanced compliance and information protection – Safeguard sensitive data with Data Loss Prevention (DLP) policies across email and documents. Azure Information Protection lets you classify, label, and encrypt data automatically based on sensitivity.
• eDiscovery and legal hold – Search across Exchange, SharePoint, and OneDrive to identify and preserve electronically stored information for litigation or regulatory response, a critical capability for legal and compliance teams.
• Centralised administration and deployment – The Microsoft 365 admin centre gives IT full control over user accounts, device policies, app deployment, and security settings. Streamline onboarding and offboarding while maintaining a consistent security posture.
• Web and mobile apps included – When users are away from their primary devices, the web-based Office apps and fully featured mobile apps for iOS and Android keep them productive without compromising document fidelity.
• Predictable 24-month subscription – A fixed two-year term locks in your cost per user and guarantees access to all feature updates released during the subscription period, simplifying budget planning.

What's included with your purchase

Your purchase from Lizensa includes a genuine Microsoft Office 365 E3 24-month subscription license, delivered digitally. This is an annual-commitment license type, meaning the subscription is active for a fixed 24-month term and is designed for commercial and enterprise use. You will receive a clear activation link and guidance to redeem the license against a Microsoft 365 tenant. This is not a one-time purchase or a lifetime license; it is a subscription that provides continuous access to the cloud services and desktop applications for the duration of the term.

Specifically, you receive:

• A digital activation link and instructions delivered by email, typically within seconds of payment confirmation.
• A 24-month subscription to the Office 365 E3 plan for the number of users purchased.
• Access to the full suite of Office desktop apps, online services, and admin tools.
• A downloadable VAT invoice, suitable for business accounting and tax purposes.

Activation requires an existing Microsoft 365 tenant, or you can create one during the redemption process. The license is valid for activation across all 27 EU member states. The software is compatible with Windows and macOS, and the cloud services are accessible from any modern web browser.

Office versions compared — which one should you buy?

Choosing the right Microsoft licence depends on your organisation's size, compliance needs, and preference for subscription versus one-time purchase models. Office 365 E3 occupies a specific strategic position in the Microsoft ecosystem.

Office 365 E3 vs. Microsoft 365 Business Standard Business Standard is an excellent choice for small to medium businesses that need desktop apps, Teams, and Exchange email. However, it lacks the advanced compliance tools that define E3. If your organisation requires eDiscovery, legal hold, Data Loss Prevention, or Azure Information Protection, E3 is the minimum edition that delivers these enterprise controls. E3 also provides unlimited OneDrive storage, whereas Business Standard is capped at 1 TB per user.

Office 365 E3 vs. Microsoft 365 E5 E5 builds on E3 by adding advanced security features such as Microsoft Defender for Office 365, audio conferencing capabilities, and Power BI Pro for data analytics. If your threat landscape demands automated investigation and response, or if you need integrated voice capabilities in Teams, E5 is the logical step up. For organisations that need core compliance and information protection without the full security stack, E3 represents the optimal balance of capability and cost.

Office 365 E3 vs. Office Professional Plus 2021 (one-time purchase) Office Professional Plus 2021 is a traditional, perpetual licence that provides the classic desktop apps for one device per user, with no cloud services included. It does not receive feature updates and is tied to a single version. Office 365 E3, by contrast, is a connected, always-evolving platform. It includes Exchange Online for email, OneDrive for cloud storage, Teams for communication, and the full compliance toolkit. For any business that relies on collaboration and needs to manage data across devices, the subscription model is the superior investment.

Who is this edition best for? Office 365 E3 is purpose-built for medium to large enterprises, regulated industries, legal practices, financial services firms, and any organisation that must enforce strict data governance. It is ideal for IT-managed environments where centralised deployment, policy enforcement, and audit readiness are non-negotiable.

System requirements / compatibility

Office 365 E3 is a cloud-first platform with desktop and mobile components. The desktop applications are compatible with both Windows and macOS. The cloud services, including Outlook on the web, SharePoint, and Teams, are accessible through modern web browsers on any operating system.

Minimum system requirements (desktop apps):

• Operating System: Windows 10, Windows 11, or the three most recent versions of macOS.
• Processor: 1.6 GHz or faster, 2-core processor.
• Memory: 4 GB RAM minimum; 8 GB recommended for optimal multitasking performance.
• Storage: 4 GB of available disk space.
• Architecture: 32-bit and 64-bit editions are supported where the operating system and product edition allow.
• Internet: Internet access is required for activation, installation, and to access cloud-based services. A broadband connection is recommended.

Language support: This licence supports the Office applications in English, German, French, Dutch, and Polish. Users can install and switch between these languages from their account settings.

Important notes: Exact requirements can vary by edition and feature update. We strongly recommend validating your specific environment against the official Microsoft vendor documentation before activating your product. The product is delivered digitally; no physical media is shipped.

Installation and activation

You can also access your licence details at any time through your Lizensa customer account.

FAQ — frequently asked questions

Is Microsoft Office 365 E3 a subscription or a one-time purchase?

This is a 24-month subscription licence. Your right to use the software and cloud services is active for the full two-year term. Unlike a one-time purchase, the subscription includes continuous feature updates and access to all included cloud services for the duration.

What is the difference between an annual subscription and a perpetual licence?

A perpetual licence, like Office Professional Plus 2021, is a one-time purchase that provides the desktop applications in a fixed version with no cloud services.

What happens when the 24-month subscription ends?

Near the end of the term, you will have the option to renew the subscription to maintain uninterrupted access to the applications and services.
