Office 2010 recently reached EOL and users should be on Office 2013 or higher to replace existing suite.  The Office 365 family is also a popular option for business users so they continuously stay on latest product capabilites.

Microsoft on Monday noted the end of support for Office 2010 and Office 2016 for Mac, which are “perpetual-license” versions of Microsoft’s productivity suite software.  The end-of-support phase means that no more software updates arrive from Microsoft for those products, including security patches. Perpetual-license Office products follow Microsoft’s traditional 10-year support model, called the “Fixed Lifecycle Policy.”  Microsoft 365 applications follow the Modern Lifecycle Policy,” where support is contingent upon the software staying up to date and there are no long-term product lifecycle servicing promises extended to organizations.
