While Office 2010 apps will continue to function, support for Office 2010 will be ending on October 13, 2020. If you have not begun to upgrade your Office 2010 environment yet, it is recommended you start soon.
Like most Microsoft products Office 2010 has a support lifecycle during which bug and security fixes are provided. The lifecycle lasts for a certain number of years from the date of the product’s initial release, in this case, 10 years. This means Microsoft will no longer be providing technical support for issues, bug fixes for any issues that are discovered, or security fixes for any vulnerabilities that are discovered. If you are planning an upgrade, you have options between the latest versions of Office. This includes Microsoft 365 apps or Office 2019. A key difference to note between the two is that Microsoft 365 apps is updated regularly with new features, whereas Office 2019 only includes the same features from when it was released in October 2018.
