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 Mainly because outdated versions are more vulnerable to hackers, particularly in the case of opening malicious emails, documents, or images.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, 5 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, 5 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…

Publisher ending
Microsoft Publisher is being discontinued (Microsoft calls it ‘end of life) on 13 October 2026 or about 2 years, 5 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 2019 for Mac

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.
