Browse Office Versions

Our Office range covers every generation of Microsoft’s productivity suite currently in active use. Here is a quick overview of what is available:

The 2016 edition

Office 2016 remains a reliable choice for users who prefer a proven, stable release. Released in September 2015 for consumers, it introduced real-time collaboration and a refined ribbon interface across all core apps.

The 2019 edition

Office 2019 brought focused improvements to Excel (new functions and charts), Word (improved inking tools), and PowerPoint (Morph transitions and Zoom). Popular editions include Office 2019 Professional Plus for Windows and Office 2019 Home and Business for Mac.

The 2021 edition

Launched in October 2021, Office 2021 is the most popular version in our range. It added co-authoring in Word and Excel, expanded XLOOKUP and other advanced functions, and integrated Microsoft Teams as a built-in communication tool. Top picks include Office 2021 Professional Plus for Windows and Office 2021 Home and Business for Mac.

The 2024 edition

For users who want the very latest perpetual-licence release, Office 2024 delivers the newest features, updated AI-assisted tools, and extended mainstream support — all without a subscription commitment.

How to Choose the Right Edition

With several versions and editions available, the right choice depends on a few straightforward factors:

1. Your platform — Are you on Windows or macOS? Both are covered, so make sure to select the correct platform edition.

2. Your use case — Home & Student covers Word, Excel, and PowerPoint for everyday tasks. Home & Business adds Outlook. Professional Plus adds Access, Publisher, and advanced enterprise features.

3. How current you need to be — for the 2021 and 2024 carry longer mainstream support timelines. Note that Microsoft ended mainstream support for Office 2019 in October 2025, so users requiring the latest security patches may wish to step up to a newer release.

4. Activation type — Retail keys activate on one device permanently. Bind-to-Account keys tie the licence to your Microsoft account, making future reinstallation straightforward. OEM keys are tied to the original machine.

Frequently Asked Questions

What is the difference between Office 2019 and 2021?

Office 2021, released in October 2021, builds on the 2019 version, with additional features including co-authoring in Word and Excel, new Excel functions such as XLOOKUP, Morph and Zoom enhancements in PowerPoint, and built-in Microsoft Teams integration. For most users buying a new licence today, the 2021 or 2024 is the stronger choice. You can compare both on the official Microsoft Office 2019 overview page.

Are these Office licence keys genuine?

Yes. Every key sold at Buy Now Key activates directly through Microsoft’s official servers. Activation is carried out using Microsoft’s own tools and processes — the same method as purchasing a box copy in a retail store.

Do I need an internet connection to install Office?

You will need an internet connection to download the installer from Microsoft and to complete the initial activation. After activation, all core desktop apps — Word, Excel, PowerPoint, and Outlook — work fully offline.

What is the difference between a Retail key and a Bind-to-Account key?

A Retail key activates Office on one specific device and stays tied to that machine. A Bind-to-Account key links the licence to your Microsoft account instead, which means you can reinstall it on the same or a replacement device by simply signing in to your account — making it the more flexible option for most users.

Can I use the same Office key on both Windows and Mac?

No. Microsoft Office keys are platform-specific. A Windows key will not activate an Office installation on macOS and vice versa. Be sure to select the correct platform when purchasing — separate Windows and Mac editions are available across all versions in this category.

Where do I find installation instructions after purchasing?

Detailed, step-by-step guides are available on the site for every edition. For example, you can follow the Office 2021 Professional Plus activation guide for Windows or the Office 2021 Home and Business for Mac guide. Your order confirmation will also include direct links relevant to your specific purchase.
