Microsoft will regularly launch Microsoft 365 application updates, including Word, Excel, PowerPoint, Outlook, Teams, OneNote, Visio, and more. These updates are governed by Microsoft's Modern Lifecycle Policy, which means that the product will continue to be supported as long as the customer remains up-to-date according to the product's service and system requirements, and has a license to use the software in question. Under this policy, Microsoft 365 Apps will end support for three legacy Windows operating systems in January 2023.
Microsoft has issued an announcement saying that from January 10, 2023, Microsoft 365 applications will completely stop supporting Windows 7, Windows 8.1 and Windows Server 2008 R2 systems.
Although Microsoft 365 Apps on the above operating systems are no longer supported, they will still receive upgrades under the Extended Security Update (ESU) program for customer-paid versions. The plan is to end support for the three operating systems mentioned above on January 10, 2023, so Microsoft 365 Apps will end support entirely on the same day. In addition to not being able to access security updates, new installations will also be blocked.
As expected, the only solution is to immediately update to a newer supported Windows operating systems, such as Windows 10 and Windows 11, and Microsoft encourages customers to review the support lineup to determine which operating system best suits their support and compatibility needs.
