October 13 officially marked the last day of support for Office 2010 and Office 2016 for MacOS users.

Following the latest updates made ahead of that date, Microsoft has suspended all further security updates, bug fixes, and technical support. Office 2010 and 2016 for Mac can still be used, but will no longer be officially supported.

On the same day, support for Office 2010 was also discontinued for Windows OS users. However, their support for Office 2016 will last until October 14, 2025.

It is important to note that Microsoft will not block users who use older versions of Office from connecting to Microsoft 365 / Office 365 services, but warned that those who do will not receive all the latest updates and feature updates.
