Office 2021 Professional Plus: buy once, no subscription

Office 2021 Professional Plus is the edition to buy if you want the full desktop Office applications without a Microsoft 365 subscription. It installs Word, Excel, PowerPoint, Outlook, OneNote, Publisher and Access on Windows (the Mac option supplies the macOS edition of Office 2021, which covers Word, Excel, PowerPoint, Outlook and OneNote), activates once and stays installed. There is no renewal and nothing to cancel.

AutoSoftKey supplies it as a pre-owned digital licence with the product key, order documentation and activation guidance by email, for 1, 3 or 5 devices. If you are weighing it against a subscription, our Office 2021 vs Microsoft 365 guide compares the two properly.

What is included

• Word, Excel, PowerPoint: the current 2021 feature set including XLOOKUP, dynamic arrays and co-authoring when files are stored in OneDrive.
• Outlook: desktop email, calendar and contacts for Microsoft, Exchange, Google and IMAP accounts.
• Access and Publisher (Windows): desktop databases and desktop publishing, which subscription-free Home & Business editions omit.
• OneNote: note-taking synced across devices.
• Perpetual licence: a fixed version with security updates from Microsoft until October 2026, then continued use without updates.

Who buys Professional Plus

Small businesses that need Access or Publisher, professionals who prefer a one-off cost, and anyone replacing an ageing Office 2016 or 2019 install. Households that only need Word, Excel and PowerPoint can look at Office 2019 Home & Student; teams that want cloud storage, Teams and always-current apps should consider Microsoft 365 Business Standard.

Choosing devices and platform

Pick Windows or Mac and the number of devices — 1, 3 or 5. Access and Publisher are Windows-only applications, so Mac buyers receive the Mac suite without them. The multi-device options suit a small office or a family; ask support if you need to know whether a multi-device option is one entitlement or a bundle of separate licences before you buy for a team.
