Microsoft has officially announced Office 2016 and Office 2019 end of support, as of October 14, 2025. After this date, there will be no extensions and no extended security updates.
While your Office 2016 and Office 2019 apps will continue to work, using them after the end of support could expose your organisation or home devices to serious security risks.
What does “End of Support” mean?
Once Office 2016 and Office 2019 reach end of support:
- You will no longer receive technical support, bug fixes, or security updates from Microsoft.
- No more security patches means your devices could be vulnerable to new viruses, malware, or spyware.
- You won’t receive updates through Microsoft Update.
- Phone or chat technical support for these versions will stop.
- Most online help content for these versions will be retired and no longer updated.
Why does end of support matter?
What are the risks after support ends?
Security risk is the heightened possibility that unpatched software could be exploited by malware, ransomware, or other cyber threats because known vulnerabilities are no longer fixed.
Compatibility risk is the chance that other applications, add-ins, or connected services may stop working properly with outdated Office versions over time.
How does this affect users?
Can Office still be used after support ends?
Yes, Office applications will continue to function on your devices after October 14 2025, but they operate without ongoing updates or support from Microsoft.
Example: Using Outlook after support ends
A company that uses Outlook from Office 2019 can still open and edit emails after the end-of-support date. However, newly discovered security flaws won’t be patched and compatibility with modern mail server features may degrade over time.
What are your options?
If you’re using Office 2016 or Office 2019 at home or in your business, you should start planning an upgrade before October 2025.
