Office 2016 and 2019 after the end of support: what changed
Support for both ended on 14 October 2025.
What it means
The apps keep working, but there are no more security updates.
The practical risk
Malicious documents remain the main danger. Be careful with attachments.
When old Office is still fine
A PC used offline, or for simple tasks.
What to move to
Office 2024 if you want to pay once, Microsoft 365 if you want the cloud. Compare them in Office 2021 vs 2024 vs Microsoft 365.
How to upgrade cleanly
Remove the old Office, restart, install the new version, and activate.
Will my files open in Office 2024?
Yes. Old documents open normally.
