Frequently Asked Questions (FAQ)

Is Office 2016 still supported in 2025?

Mainstream support ended in October 2020. Microsoft provided extended security updates through October 14, 2025. After this date, you'll still be able to use Office 2016, but no new security patches will be released. Consider upgrading to Office 2019, 2021, or 2024 for ongoing protection.

Can Office 2016 run on Windows 11?

Yes! Office 2016 is compatible with Windows 7, 8, 8.1, 10, and 11. It also runs on Windows Server 2012 R2 and later.

What makes Office 2016 different from newer versions?

Office 2016 introduced real-time co-authoring, Tell Me search, smart attachments in Outlook, and improved ink tools. However, it lacks features added in 2019+ (like Focus Mode, XLOOKUP, Morph transitions). It's a solid choice if you want a familiar, no-frills experience.

Does Office 2016 Pro Plus include Access and Publisher?

Yes! Access and Publisher are included in the Professional Plus edition. Home & Student and Home & Business editions do not include them.

Can I install Office 2016 on more than one PC?

No. A single Office 2016 Pro Plus license is valid for one PC only. For multi-PC setups, you'll need separate keys. Contact DotKeys for volume licensing.

Can I install Office 2016 alongside Office 2019/2021/2024?

Microsoft doesn't officially support running two versions of Office side-by-side. It can cause conflicts. We recommend uninstalling older versions first.
