Microsoft Office 2021 Professional Plus

A complete productivity suite, free from subscription fees

Microsoft Office 2021 Professional Plus is the definitive, one-time purchase productivity suite for professionals and businesses who demand full control over their software. This is not a cloud-dependent subscription that holds your tools hostage behind a monthly paywall. It is a permanent license granting you unrestricted access to the classic, powerful desktop versions of Word, Excel, PowerPoint, Outlook, Access, Publisher, and OneNote. You pay once, and the software is yours to use for as long as your hardware supports it.

This edition is engineered for the heavy lifter: the financial analyst building complex, linked spreadsheets; the marketing manager crafting pixel-perfect publications; the database administrator managing critical business information; and the IT professional deploying a standardised, reliable toolkit across an organisation. Unlike the slimmed-down Home editions, Professional Plus includes the full spectrum of business-critical applications, notably the powerful database management system, Access, and the desktop publishing application, Publisher. The license type is shown for the variant you select. Delivered digitally by Lizensa, you gain immediate access to a genuine, verified license, backed by full EU consumer protection and expert support.

Key features and benefits

What's included with your purchase

When you purchase Microsoft Office 2021 Professional Plus from Lizensa, you receive everything needed for a swift, secure, and compliant installation. Your order confirmation email, which typically arrives within seconds, contains your unique, genuine product key and a direct, official download link sourced from Microsoft's content delivery network. You are not purchasing a shared volume license key or an account-locked subscription; you are buying a legitimate, perpetual license for one device.

A detailed, step-by-step activation guide is included, walking you through the process from download to activation. Activation requires a one-time internet connection and a free Microsoft account to link the license. Once activated, the software is permanently licensed for that device. For business accounting, a full EU-compliant VAT invoice is provided with every purchase. The license is compatible with Windows 10 and Windows 11, and the installer supports both 32-bit and 64-bit architectures, automatically selecting the optimal version for your system.

Office versions compared — which one should you buy?

Choosing the right Microsoft Office version depends entirely on your needs. The primary decision is between a one-time purchase, like this Office 2021 Professional Plus, and a Microsoft 365 subscription.

A Microsoft 365 subscription provides ongoing access to the latest, ever-evolving cloud-connected apps, 1 TB of OneDrive storage, and regular feature updates for a monthly or annual fee. It is ideal for users who always want the newest features and work across multiple devices, including tablets and phones.

Office 2021 Professional Plus is a static, one-time purchase. You get a fixed set of classic desktop apps with no future feature updates, but also no recurring costs. It is the superior choice for users who:

• Prefer a predictable, one-off budget over a perpetual operational expense.
• Require a stable, unchanging software environment for compatibility and training purposes.
• Do not need cloud storage or mobile apps.
• Need the business-specific applications Access and Publisher, which are not included in the standard Microsoft 365 Business plans or the lower-tier Office Home & Business 2021.

This edition is the flagship for commercial users who need the complete toolset without a subscription. It is fully compatible for opening and editing files created in older versions of Office, ensuring seamless collaboration with partners and clients who may not have upgraded.

FAQ — frequently asked questions

Is this a subscription or a one-time purchase?

This is a one-time, perpetual license for Microsoft Office 2021 Professional Plus. You pay a single upfront cost and can use the software indefinitely. There are no monthly or annual fees, and the license never expires.

What is the difference between a retail and an OEM license?

A retail license is transferable. Whether the licence can be moved to a new device depends on the licence type of the variant you select. An OEM license is typically pre-installed on a new PC and is permanently locked to that first device, making it non-transferable.

How fast will I receive my license key after purchase?

Our delivery process is fully automated and digital. In the vast majority of cases, your email containing the product key, download link, and VAT invoice will arrive within 60 seconds of your payment being confirmed.

Is this a genuine and legal Microsoft license?

Absolutely. Lizensa supplies only 100% genuine, verified licenses sourced from authorised European distributors. You will receive a unique product key that activates directly with Microsoft's servers, ensuring full compliance and legitimacy for commercial use.

What should I do if I have trouble activating the software?

First, ensure you are entering the key exactly as provided and that your internet connection is stable. If the issue persists, contact our free, multilingual technical support team. We can provide direct assistance and, in the rare case of a faulty key, will provide a replacement.

Can I reinstall this software or transfer it to a new computer?

Yes. More importantly, transfer rights depend on the license type of the selected variant.

Does this version of Office work on a Mac?

No. Microsoft Office 2021 Professional Plus is designed exclusively for the Windows operating system, specifically Windows 10 and Windows 11. It is not compatible with macOS, iOS, or Android.

What payment methods do you accept?

Our Stripe-secured checkout accepts a wide range of payment methods, including all major credit and debit cards (Visa, Mastercard, American Express), SEPA direct debit, iDEAL, BLIK, and Google Pay.

Do you provide a VAT invoice for business purchases?

Yes, a detailed, EU-compliant VAT invoice is automatically generated and included with your order confirmation email. This is suitable for business accounting and tax deduction purposes across all EU member states.

What is your refund policy?

We offer a 14-day right of withdrawal in compliance with EU consumer protection law. If you have not yet activated or downloaded the software, you are eligible for a full refund. Our support team can guide you through this simple process.

Which apps are included that I don't get with Office Home & Business 2021?

The key additions in this Professional Plus edition are Microsoft Access, a powerful relational database management system, and Microsoft Publisher, a desktop publishing application for creating professional print and digital materials. These are not available in the Home & Business version.

Do I need to be online to use the applications?

An internet connection is required only for the initial download and one-time activation. After that, all core applications—Word, Excel, PowerPoint, Outlook, Access, Publisher, and OneNote—are fully functional offline.
