Microsoft today announced the end of support for Office 2010 and Office 2016 for Mac. From today, Microsoft will not be releasing bug fixes, or security updates for these products. Also, Microsoft won’t offer technical support for these products. If you haven’t already started the Office 2010 migration process, you need to start now. Also, to use services like Exchange Online and SharePoint Online, you need Microsoft 365 Apps, Office 2019, or Office 2016.
Office 2016 include applications such as Word, Excel, PowerPoint, and Outlook. They’re available as a one-time purchase for use on a single PC. Microsoft 365 plans include premium versions of these applications plus other services that are enabled over the Internet, including online storage with OneDrive and Skype minutes for home use. Support for Office for Mac 2011 ended October 10, 2017. Rest assured that all your Office 2011 apps will continue to function—they won't disappear from your Mac, nor will you lose any data.
