Microsoft Office support end dates checklist

Checklist when your version of Microsoft Office will stop getting security bug and software bug fixes, what Microsoft calls the end of support.

This is important because software updates are necessary for Office apps. Mainly because outdated versions are more vulnerable to hackers, particularly in the case of opening malicious emails, documents, or images. And, of course, these will compromise your system if you do not have the latest updates.

If you’ve noticed after reading this article that you’re no longer receiving security updates, it’s time to switch to a modern version. Like Office 2021 or Microsoft 365.

Support End Dates

Microsoft is still issuing security updates for these Office versions as of April 2024.

Microsoft 365

Microsoft 365 is always kept updated with the latest security updates, bug fixes and features as long as you have a current Microsoft 365 subscription and have not paused updating.

Office 2024

Office 2024 hasn’t been released yet, but we already know that it will be supported for only five years from release date. That’s the same shortened support life as Office 2021 and Office 2019 have.

Office 2021

Office 2021 gets support for Windows and Mac versions until 13 October 2026 or about 2 years, 3 months from today

That’s half Microsoft’s supposedly ‘fixed’ lifecycle policy of 10 years.

Office 2019 for Windows

Office 2019 for Windows gets security updates until 14 October 2025. or about 1 year, 3 months from today .

For mainstream support, the end date is October 10 2023, whilst extended support is 14 October 2025 but with an important exclusion…

Office 2016

For mainstream support, has already expired on October 13, 2020 or about 3 years, 8 months ago .

Office 2016 gets extended support for Windows security updates until 14 October 2025 or about 1 year, 3 months from today but with an important exclusion …

Publisher ending

Microsoft Publisher is being discontinued (Microsoft calls it ‘end of life) on 13 October 2026 or about 2 years, 3 months from today .

From that date no version of Publisher will be supported. No security or other bug fixes for any Publisher.

No Longer Supported

There are several Office apps that are no longer supported BUT any updates and security fixes are still available. Hackers take advantage of security holes in older software that’s rarely updated so it’s worth checking for anything that Microsoft has made available.

Office 2013

Office 2013 extended support ended on 11 April 2023 or about 1 year, 2 months ago . Mainstream support ended in 2018.

Office 2019 for Mac

Office 2019 for Mac had security updates until 10 October 2023 or about 8 months ago . No extended support is available.

Office 2016 for Mac

No extended support was offered, and mainstream support ended in 2020.

Office 2011 for Mac

No longer receives security updates, support ended in 2017.

Office 2010

Mainstream support ended in 2015 whilst extended support ended in 2020.

Office 2007, 2003, XP, 2000, 97 and 95

Plus all older versions no longer receive security updates.

Mainstream vs Extended Support

So, what’s the main difference between Mainstream and Extended Support?

Each Office perpetual licence (i.e not subscription) version gets Mainstream support for several years when its first released.  That means Office program might get new or updated features as well a bug fixes and patches for security problems.

After the Mainstream support has ended, Microsoft provides what they call Extended Support. Feature changes are dropped, but they will continue to issue security updates until the extended support period is over.
