A checklist of when your version of Microsoft Office will stop getting security bug and software bug fixes, what Microsoft calls the end of support.
- Support End Dates
- No Longer Supported
- Mainstream vs Extended 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 Mainly because outdated versions are more vulnerable to hackers, particularly in the case of opening malicious emails, documents, or images.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.

Mainstream vs Extended Support
So, what’s the main difference between the 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.
