• One-time purchase for 1 PC
• Classic 2021 versions of Word, Excel, PowerPoint, and Outlook, plus Publisher and Access
• Microsoft support is included for the first 60 days at no extra cost
• Compatible with Windows 11 and Windows 10

After more than 30 years on the market, Microsoft has decided to stop investing much attention into their classic offline PC productivity apps, renaming the entire Office suite and transforming it into an active subscription service called Microsoft 365 which features many other benefits alongside access to the latest versions of all Microsoft apps (such as the ability to install and use them on multiple PCs, expanded cloud storage, advanced security features for both single users and their family members, and more).

However, they have not forgotten their legacy in the offline app space, offering users of all knowledge levels and document productivity needs access to a wide selection of the Classic 2021 version of their most popular apps.

Office Professional 2021 includes the following apps that can be installed on a single PC or Mac:

Word - An award-winning text processing and proofreading application for editing documents for home, school, and commercial needs. It supports all modern and legacy document file formats, a large library of templates, macro addons, plugin support, and much more.

Excel - A powerful application for the creation, organization, analysis, and computation of data in tabular form. It features extensive support for data visualization, graphing, macro add-ons, and interoperability with many Office apps.

PowerPoint - A Powerful and eye-catching presentation editing app that can fulfill the needs of home, school, and business users.

Outlook - Fully featured email and personal information manager with built-in tools for calendars, folders, data aggregation, and appointment scheduling.

Publisher - Document publishing editor, focused on page layouts and graphic elements that are of great importance for printed projects or web design creations.

Access - Comprehensive database management system.

All these apps can be used offline without any limitation, and they also feature integration with several other Microsoft cloud-powered apps, such as Microsoft Teams and OneDrive (both accessible as free apps).

As it is clearly obvious, this product selection is focused only on offline apps and lacks many online-focused apps and services that are currently accessible only via Microsoft 365 subscriptions.

MS Office Professional 2021 includes the latest versions of all Microsoft productivity apps, enhanced built-in support for online collaboration via Microsoft Teams or Office webapps (including real-time editing and document creation by multiple online users), advanced security, and more.

To download and start using all these apps on any modern PC running Windows 10 or Windows 11, active license holders can get them all directly from the Microsoft Store or by simply visiting their Microsoft Account page and “Services & subscriptions” section, where all their purchases, active subscriptions, and downloadable apps are listed.

Included apps can all be easily used on any modern PC that matches the minimum system requirements needed by those operating systems.

FAQs

Does Office Professional 2021 require a Microsoft 365 subscription?
No subscription is required because this version is licensed as a perpetual one-time purchase that you activate with a product key and then own permanently. You still receive essential security updates, but feature upgrades are limited to what comes with the 2021 release.

Can Office Professional 2021 be installed on multiple computers?
The license is typically valid for a single PC, meaning you can activate it on one device at a time unless you purchased a special volume or business license. If you change computers in the future, you can usually transfer the license by deactivating it on the old machine before activation on the new one.

Is Office Professional 2021 compatible with Windows 10 and Windows 11?
Yes, it works on both Windows 10 and Windows 11 as long as the system meets the official minimum requirements. The suite is optimized for modern hardware, offering smoother performance, better scaling, and improved stability across the supported versions of Windows.

Do I need an internet connection to use Office Professional 2021?
You only need internet access during installation, activation, and for receiving security updates, but all included applications function fully offline after activation. This makes it suitable for users who prefer local software without constant cloud dependence.

What support and updates does Microsoft provide for Office Professional 2021?
Microsoft supplies security updates and bug fixes for the official support lifecycle, ensuring the suite remains safe and stable. However, new features introduced in future Microsoft 365 versions are not added to Office 2021, since perpetual releases only receive maintenance updates rather than continuous feature evolution.
