PSA: Microsoft 365 Apps will soon no longer be supported on these older operating systems

Microsoft regularly releases updates to Microsoft 365 Apps, including Word, Excel, PowerPoint, Outlook, Teams, OneNote, Visio, and more. These updates are governed by Microsoft’s Modern Lifecycle Policy, which means that a product will remain supported as long as a customer remains current in accordance with the product’s maintenance and system requirements and has a license to use such software. Under this policy, Microsoft 365 Apps is set to drop support on three older operating systems in June 2023.

Microsoft has released a notice that Microsoft 365 Apps will no longer be supported on Windows 7, Windows 8.1, and Windows Server 2008 R2 starting January 10, 2023.

Although Microsoft 365 Apps on the aforementioned operating systems were already unsupported, they still received security updates under the Extended Security Updates (ESU) program that some customers paid for. This program ends for the three operating systems mentioned above on January 10, 2023, therefore support for Microsoft 365 Apps on these will also be fully removed on the same date. In addition to losing access to security updates, new installations will also be blocked.

As expected, the only workaround is to immediately update to a newer, supported operating system. Microsoft encouraged customers to review this support matrix to determine which operating system would best meet their support and compatibility needs.
