Question 1

What happens when Office reaches end of life?

Accepted Answer

When Office reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 7 Office versions are already EOL. The latest supported version is Office 2024, maintained until October 9, 2029. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Office 2024 still supported?

Accepted Answer

Yes. Office 2024 is actively supported until October 9, 2029. It receives security patches and bug fixes. Check the version table above for the full list of supported Office releases and their exact end-of-life dates.

Question 3

Is it safe to use Office after end of life?

Accepted Answer

No. Running Office after EOL is not safe for production systems. Once a version reaches end of life, newly discovered CVEs are published publicly but never patched — leaving your systems permanently exposed. The only safe path is upgrading to an actively supported Office release.

Question 4

How to upgrade from Office 2019 to Office 2024.x?

Accepted Answer

To upgrade Office from 2019 to 2024: (1) review the official migration guide for breaking changes, (2) test your application against the new version in a staging environment, (3) update dependencies that have version constraints, (4) run your full test suite, (5) deploy with a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before EOL.

Question 5

When is the next Office LTS version?

Accepted Answer

Office 2024-ltsc is the current Long Term Support release, maintained until October 9, 2029. LTS versions are recommended for production deployments that prioritize long-term stability over new features. Plan your upgrades to coincide with LTS releases whenever possible.

Question 6

How long does Office support each version?

Accepted Answer

On average, Office supports each release for approximately 92 months (~7.7 years). LTS releases like Office 2024-ltsc have extended support windows — maintained until October 9, 2029. The exact EOL date for each version is listed in the table above.
