Yes, you can still find one-time purchase licenses for Microsoft Office 2016 through reputable third-party retailers, even though Microsoft no longer sells it directly. However, it is critical to understand that its official support, including vital security updates, ended on October 14, 2025, posing significant risks for users.
Key Takeaways
- One-Time Purchase Available: Office 2016 can still be acquired as a perpetual, one-time purchase license from third-party software vendors, not directly from Microsoft.
- End of Support is Critical: According to Microsoft's official lifecycle policy, extended support for Office 2016 concluded on October 14, 2025.
- No More Security Updates: After the end-of-support date, Office 2016 no longer receives security patches, leaving your system vulnerable to malware and other cyber threats.
- Secure Alternatives Exist: Modern, fully supported one-time purchase options like Office 2021 and Office 2024 offer better security, new features, and long-term peace of mind.
- Functionality Remains, Risks Increase: The core applications of Office 2016 will continue to function, but using them without security updates is not recommended, especially in a connected environment.
Is Office 2016 a One-Time Purchase?
Office 2016 is a perpetual license, which means you buy it once and own it forever for use on a single computer without any recurring fees. This model is distinct from Microsoft 365, which requires an ongoing monthly or annual subscription. For users who prefer to avoid subscriptions and own their software outright, a perpetual license like Microsoft Office 2016 Professional Plus has long been an attractive option.
The one-time purchase includes the classic desktop applications such as Word, Excel, PowerPoint, and Outlook. Once installed and activated with a genuine product key, the software is yours to use indefinitely on the device it was installed on. This straightforward ownership model is a key reason why many users still seek out these licenses today.
What 'End of Support' Means for Office 2016 Users
The most important factor when considering an Office 2016 license is its support status, as Microsoft ended all extended support for it on October 14, 2025. This date marks the end of the software's lifecycle, which means Microsoft no longer provides security updates, non-security updates, bug fixes, or any form of technical assistance. While the applications will still launch and operate, they become a frozen snapshot in time.
Using software without security updates is a significant risk. Cybercriminals actively search for and exploit vulnerabilities in unsupported software. Without patches from Microsoft, any new flaws discovered in Office 2016 will remain unpatched forever, creating a permanent entry point for malware, ransomware, or data theft. This is especially dangerous for applications like Outlook, a common target for malicious email attachments. For a deeper dive into this topic, see our guide on the Office 2016 end of life.
Where Can You Safely Buy an Office 2016 License?
You can safely purchase a genuine Office 2016 license from established third-party software retailers who specialize in providing legitimate software keys. Since Microsoft has shifted its sales focus to Microsoft 365 and newer perpetual versions, the third-party market is the only remaining channel for acquiring older versions like Office 2016. However, caution is paramount.
To avoid counterfeit software, you should only buy from vendors who guarantee genuine licenses and provide clear instructions for download and activation through official Microsoft channels. A legitimate purchase ensures you receive a valid product key that can be authenticated with Microsoft's servers. This not only guarantees the software will work correctly but also protects you from the malware often bundled with pirated software. It's always wise to ensure your software is genuine to protect your data and device.
