What does Microsoft Office 2016 End of Life Mean
Mainstream Support
The mainstream support phase generally refers to the first 5 years of a product’s life cycle. During this period, the product receives feature updates, security patches, and service packs. Users can also request non-security updates, incident support, or product feature changes.
For Microsoft Office 2016, the mainstream support phase was from 22nd September 2015 to 13th October 2020, with Extended End Date being 14th October 2025.
Extended Support
The Extended Support phase is the final five years of a product's lifecycle. During this period, a product only receives security updates, and users can no longer request new design changes or non-security updates.
End of Support
As stated, after a product reaches the end-of-life phase, Microsoft will stop providing most forms of updates and support for it, making it a security risk.
For customers who are still in the upgrade process or those who need to keep using legacy products, Microsoft offers one final option: the Extended Security Update (ESU) program.
Why Can’t I Just Keep Using Microsoft Office 2016?
As stated, once Microsoft Office 2016 reaches the EOL phase, they will no longer receive critical security updates. This puts them at increased risk of cyberattacks and non-compliance. The option to receive a few more years of security updates comes with a premium, a paid subscription to Microsoft.
To add to this, the newer versions of Microsoft Office simply offer way more features and better performance and modern security.
