Microsoft Office 2021 Professional Plus

Microsoft Office 2021 Professional Plus

Office 2021 Professional Plus is the most recent version of the world's most powerful — and best-known — office suite. Use it at home or professionally: Word, Excel, PowerPoint, OneNote, Outlook, Publisher, Access, and Teams on one Windows PC, forever.

Key Facts

Features

The Microsoft Office 2021 Professional Plus license is perpetual. Once installed it stays active on that device — there is no recurring subscription and no activation expiry. You get new co-authoring tools, real-time translation, updated editing features, motion graphics, and performance improvements across the full suite. As a refresh of the traditional office package, Office 2021 Professional Plus keeps the workflow that millions already know, with targeted upgrades where they matter most.

Office 2021 Professional Plus license versions

Office 2021 Professional Plus is sold in two variants — pick the one that matches how you plan to use the software:

• Bound — the license is linked to your Microsoft account. You can deactivate it on one PC and reinstall on a different one. This is the flexible option for users who upgrade hardware or use multiple devices over time.
• OEM — the license activates once on a single PC and stays tied to that machine. If the PC is reinstalled or replaced, the license cannot be moved. This is the cost-effective option for a long-term single-machine setup.

Both variants deliver the same Office 2021 Professional Plus software — only the activation and transfer rules differ.

Frequently Asked Questions

Is this a subscription or a one-time purchase?

Office 2021 Professional Plus is a one-time purchase (perpetual license). You pay once and use it indefinitely — no recurring fees.

What do I receive after purchase?

You receive a license key by email along with download and installation instructions. Your key is delivered instantly during office hours, or within 24 hours at all other times.

What is the difference between Bound and OEM?

A Bound license is linked to your Microsoft account and can be transferred to a new PC. An OEM license activates once on a single PC — if you format the computer, the license is lost.

Which apps are included?

Word, Excel, PowerPoint, OneNote, Outlook, Publisher, Access, and Microsoft Teams (downloaded separately for free).

Is it compatible with Mac?

No. Office 2021 Professional Plus is for Windows only (Windows 10 or 11). For Mac, see Office Home and Business 2021.

Can I reinstall it?

With a Bound license, yes — you can reinstall using your Microsoft account. With an OEM license, reinstallation on the same device may work, but a new installation on a different device is not possible.
