Microsoft Office 2016 Professional Plus – Product Key (1 PC)

Office 2016 Professional Plus Key: What You Are Buying

This page sells one genuine Office 2016 Professional Plus product key that licenses the full 2016 desktop suite on a single Windows PC. The 25-character key arrives by email together with the download options and an illustrated activation guide. You pay once, the apps install locally on your drive, and nothing renews or expires: Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher stay licensed on that computer for as long as you use it.

Office 2016 is no longer Microsoft’s current release, and we want you to buy it for the right reasons. Microsoft ended support on October 14, 2025, so the suite receives no further security or quality updates. It still installs, activates and runs normally, which makes it a sensible low-cost choice for a second PC, an older Windows 7 or 8.1 machine that cannot run Office 2019 or later, an offline computer, or a workflow built around 2016-era macros, add-ins and Access databases. For a main work PC that sends email and opens files from strangers all day, a supported version is the safer buy, and we compare those options below.

Does Office 2016 Professional Plus Include Access and Publisher?

Yes. Professional Plus is the largest Office 2016 edition, and both Access 2016 and Publisher 2016 are part of it, alongside the core apps. Here is what installs on your PC:

• Word 2016: documents, mail merge, tracked changes and the Tell Me box, which finds any command when you type what you want to do.
• Excel 2016: the six chart types introduced in 2016 (waterfall, histogram, Pareto, box and whisker, treemap and sunburst), one-click Forecast Sheet, built-in Get & Transform (Power Query) and, in Professional Plus, Power Pivot for data models.
• PowerPoint 2016: presenter view, embedded video and audio, and screen recording for quick tutorials.
• Outlook 2016: email, calendar, contacts and tasks in one desktop app, with offline access to your mailbox.
• OneNote 2016: the full desktop notebook app, with sections, tags and notebooks stored locally if you prefer.
• Access 2016: relational desktop databases with tables, queries, forms, reports and VBA, still common in small-business inventory and client tools.
• Publisher 2016: page layout for flyers, newsletters, brochures and print-ready PDFs. Microsoft is retiring Publisher and Office 2024 no longer includes it, so an older Professional Plus license is one way to keep editing .pub files.
• Skype for Business 2016: the client installs too, but it only connects to an on-premises Skype for Business Server, because Microsoft retired Skype for Business Online in 2021.

Office 2016 Pro Plus vs Office 2021 and Office 2024 Pro Plus

The table shows the real trade-off. Office 2016 is the only one of the three that installs on Windows 7 and 8.1, and its Excel lacks newer functions such as XLOOKUP, IFS, TEXTJOIN and dynamic array formulas, which show a #NAME? error in Excel 2016 once a newer workbook recalculates. If your PC runs Windows 10 or 11 and you want security updates for years, the Office 2024 Professional Plus key is our recommendation. The Office 2021 Professional Plus key keeps Publisher but reaches end of support on October 13, 2026. Our Office 2021 vs Office 2024 comparison and the overview of every Microsoft Office version help if you are still deciding.

Can I Still Buy Office 2016 in 2026?

Yes. Microsoft stopped selling Office 2016 years ago, but genuine product keys remain available, and this one activates through Microsoft’s servers like any original copy. What changed on October 14, 2025 is support, not the license: Microsoft no longer ships security patches, bug fixes or technical help for Office 2016, while the apps themselves keep opening, saving and printing exactly as before. Files you create stay in the standard .docx, .xlsx and .pptx formats, so colleagues on Microsoft 365 or Office 2024 open them without conversion.

Because no new security fixes arrive, treat Office 2016 like any end-of-support software. Keep Windows itself updated, leave Protected View switched on for attachments, and do not enable macros in files you did not expect. On a PC that is mostly offline, or one used for a specific internal task, the risk is low. If the same PC handles daily email from outside your organization, consider a supported suite instead.

Professional Plus or Home and Student 2016?

Office 2016 comes in several editions, and Professional Plus is the one for people who need more than the basics. Office 2016 Home and Student covers Word, Excel, PowerPoint and OneNote for non-commercial use only, with no Outlook, Access or Publisher. Professional Plus adds those three apps and may be used for business. Need the same suite on several office computers? The Office 2016 Professional Plus 5 PC license covers five Windows PCs in one order.

Who Should Buy Office 2016 Professional Plus?

• Owners of older PCs running Windows 7 SP1 or 8.1, where Office 2019, 2021 and 2024 refuse to install.
• Teams with legacy Access databases and VBA macros that were built and tested in Office 2016 and should stay on the same version.
• Publisher users who still produce newsletters or menus in .pub format and don’t want to rebuild them in another program.
• Workshops, labs and kiosks where a PC stays offline and only needs reliable desktop apps.
• Budget buyers furnishing a spare or secondary computer who want a full Office license without a monthly fee.

Office 2016 Professional Plus System Requirements

Should you install 32-bit or 64-bit Office 2016? Choose 32-bit if you depend on older add-ins, ActiveX controls or VBA code written before 64-bit Office was common, because many of them only load in 32-bit Office. Pick 64-bit when you work with very large Excel workbooks or Power Pivot data models that need more memory than 32-bit Office can address. Only one bitness can be installed on a PC, so 32-bit and 64-bit Office cannot sit side by side.

Does Microsoft Office 2016 Expire?

No. A lifetime license means the product key activates Office 2016 Professional Plus once and keeps it licensed on that PC permanently. There is no yearly renewal, no account subscription and no reduced-functionality mode after a set number of days. You can reinstall on the same computer after a Windows reset, and our support helps if reactivation asks for a phone confirmation. What the license does not include is an upgrade path: Office 2016 will not turn into Office 2021 or 2024, and a later version needs its own key.

Office 2016 Pro Plus Key or a Microsoft 365 Subscription?

Microsoft 365 is billed every month or year and always gives you the newest apps, cloud storage and Teams. That is good value for people who use every part of it, but it adds up over several years, and the apps stop editing documents when payments end. An Office 2016 Professional Plus key is a single payment at the price shown at the top of this page, with no renewals to track. If you only need desktop documents, spreadsheets, a mail client and a database on one PC, the one-time license usually costs less over its lifetime.

Is It Safe to Buy an Office 2016 Product Key Online?

Yes, as long as the seller still answers after you have paid.

Our store belongs to Makers Unity LLC, a Microsoft partner, and every order includes a 180-day refund on keys that have not been redeemed, a free replacement if the key stops working through no fault of yours, and activation support when you reply to your delivery email.
