It is the most complete edition of Office 2021, designed for professionals, businesses, and power users who need every tool available.

Is this a one-time purchase or a subscription?

This is a one-time purchase. You pay once and receive a lifetime licence — there are no monthly or annual fees, and no Microsoft 365 subscription is required. Once activated, the software is yours permanently on the device you install it on.

How do I download and install Office 2021 Professional Plus?

After purchase, you will receive your product key by email. Visit setup.office.com, enter your key to redeem it, and then follow the on-screen instructions to download and install Office on your Windows PC. For full step-by-step instructions, see our Office 2021 Professional Plus installation and activation guide.

How many PCs can I install Office 2021 Professional Plus on?

The licence covers one activation on one Windows PC. If you reinstall Windows, move to a new computer, or need Office on an additional machine, you will need to purchase a new key. If you need a licence that can be transferred between devices, take a look at our Office 2021 Pro Plus – Bind to Account version, which ties the licence to your Microsoft account.

Does Office 2021 Professional Plus require an internet connection?

An internet connection is required during the initial download and activation process. Once Office 2021 Professional Plus is installed and activated, it works fully offline — no ongoing internet connection is needed to use the applications.

Is this licence genuine? Will it pass Microsoft validation?

Yes. You receive a genuine Microsoft product key that activates directly through Microsoft’s servers. Activation is performed through the official setup.office.com portal, ensuring your copy is fully licensed and passes all Microsoft validation checks.

Which Windows versions are compatible with Office 2021 Professional Plus?

Office 2021 Professional Plus is compatible with Windows 10 and Windows 11 (64-bit). It is not compatible with Windows 7, Windows 8, or any macOS version. Please ensure your system meets the minimum requirements: a 1.6 GHz dual-core processor, 4 GB RAM, and 4 GB of available storage.

Office 2021 Professional Plus is the full enterprise-grade edition, including Word, Excel, PowerPoint, Outlook, Publisher, Access, OneNote, and Teams. Office 2021 Home and Student includes only Word, Excel, and PowerPoint — making it a lighter option for home or school use. Professional Plus is the right choice if you need the complete toolset.

How quickly will I receive my product key after purchase?

Your licence key is delivered digitally by email, typically within minutes of completing your purchase. Check your inbox (and spam/junk folder) after checkout. If you have not received your key, contact our customer support team and we will resolve it promptly.

Does Office 2021 Professional Plus receive updates?

Yes. Office 2021 Professional Plus receives security patches and minor updates from Microsoft through October 2026, in line with Microsoft’s standard support lifecycle for this version.
