Time is running out: End of support for Office 2016 and Office 2019

Posted on September 1, 2025 by Louise Howland
On 14th October 2025, just a matter of weeks away, Microsoft will officially end support for Office 2016 and Office 2019. After that date, these versions of Office will no longer receive security updates, bug fixes or technical assistance.
Although the software will still run, continuing to use it past the deadline is a risky strategy. Unsupported systems quickly become an easy target for cybercriminals, and every day without patches increases your exposure to data breaches, compliance failures and downtime.
The business risks of waiting
With the deadline only weeks away, organisations that fail to prepare now face real and immediate risks:
- Security threats – vulnerabilities will remain unpatched and actively exploited by attackers.
- Compliance issues – running unsupported software may breach regulatory obligations and cyber insurance requirements.
- Integration breakdowns – Microsoft 365 services such as Teams, OneDrive and SharePoint will become increasingly incompatible.
- Falling behind – users will miss out on collaboration tools and AI-driven features that are shaping the modern workplace.
And it’s not just Office reaching the end of the road. Windows 10 also reaches end of life on the same date. If your organisation is still running Windows 10 devices, that’s an additional risk to address. (You can read more about that in our Windows 10 end of life blog for detailed guidance.)
Why acting now is essential
Time is running out, and if you have not already moved all your users to more modern versions of Office then you need to act now. With only weeks left, there is very little time to prepare, and delaying further will increase both risk and disruption. Acting now is vital not only to safeguard your organisation against cyber threats, but also to ensure business continuity, protect compliance status, and give staff the chance to adapt to new tools before the deadline passes. Leaving it any later risks rushed deployments, costly errors, and unnecessary exposure to threats that could have been avoided.
