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.
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
After your purchase is complete, Lizensa delivers your licence digitally. You will receive an email containing a link to activate your new Office 365 E3 subscription against your Microsoft 365 tenant. This process is typically instantaneous, with the email arriving within 60 seconds of payment confirmation. You can also access your licence details at any time through your Lizensa customer account.
Basic activation steps:
Log in to the Microsoft 365 admin centre with your tenant administrator credentials. If you do not yet have a tenant, the activation process will guide you through creating one.
Redeem the subscription using the activation link provided in your Lizensa delivery email.
Assign licences to individual users within your organisation.
Users can then download and install the Office desktop applications from the Microsoft 365 portal and sign in with their work credentials.
Because this is a subscription licence tied to your tenant, there is no traditional product key to manage. The subscription is activated at the tenant level and applied to user accounts. If you encounter any difficulties during activation, Lizensa provides free multilingual technical support to assist you. You can reinstall the desktop applications on a user's permitted devices at any time during the active subscription period by simply downloading them again from the portal.

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. An annual subscription, like this Office 365 E3 plan, provides always-up-to-date desktop apps, hosted email, cloud storage, and advanced compliance tools for a recurring fee over a defined term.
How fast will I receive my licence after purchase?
Our digital delivery is automated. In most cases, you will receive the email containing your activation link and instructions within 60 seconds of your payment being confirmed.
Is this a genuine, legal Microsoft licence?
Absolutely. Lizensa supplies only 100% genuine, verified licences sourced from authorised European distribution. You receive a fully compliant licence suitable for commercial use.
What if I have trouble with the activation process?
We provide free multilingual technical support to all our customers. If you encounter any issues while redeeming your subscription or assigning licences, simply contact our support team, and we will guide you through the process.
Can I reinstall the Office applications on a new computer?
Yes. During the active subscription period, each licenced user can install the Office desktop apps on up to 5 PCs or Macs simultaneously. If you replace a computer, you can deactivate the old installation and install on the new device from the Microsoft 365 portal.
Is this licence valid for use in my country?
This licence is valid for activation and use across all 27 member states of the European Union. It is not region-locked to a single market.
What payment methods does Lizensa accept?
Our checkout is powered by Stripe and accepts a wide range of payment methods, including SEPA bank transfers, iDEAL, BLIK, Google Pay, and major credit and debit cards.
Do you provide a VAT invoice for business purchases?
Yes, a detailed VAT invoice is provided with every purchase and is available for download from your Lizensa customer account. Reverse-charge VAT rules are applied for eligible B2B transactions.
What is your refund policy?
We offer a 14-day refund right in accordance with EU consumer protection regulations. If you have not activated the licence and it is in its original condition, you are eligible for a full refund.
Does this licence include Microsoft Teams?
Yes, Microsoft Teams is a core component of the Office 365 E3 plan, providing chat, online meetings, and calling capabilities integrated with your other Office apps and 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. If you choose not to renew, the desktop applications enter a read-only mode, and access to cloud services like Exchange Online and OneDrive is eventually deprovisioned according to Microsoft's data retention policies.
