• Note - Windows 7 End of Support and Office 365 ProPlus
  • 
    

    As announced previously, Windows 7 will be out of support after January 14, 2020. Because Office 365 is governed by the Modern Lifecycle Policy, customers are required to stay current as per the servicing and system requirements for the product or service. This includes using Office 365 ProPlus on a Windows operating system that is currently in support.

    Using Office 365 ProPlus on older, unsupported operating systems may cause performance and reliability issues over time. If your organization is using Office 365 ProPlus on devices running Windows 7, we strongly recommend your organization move those devices to Windows 10.

    [How does this impact me?]

    Even though Windows 7 will no longer be supported after January 2020, we understand Office 365 customers may need more time in their migration to a supported operating system. Through January 2023, Microsoft will provide security updates for Office 365 ProPlus on Windows 7. But, during that time, as long as the device is still running Windows 7, Office 365 ProPlus won’t receive any new features updates.

    [What should I do to prepare for this change?]

    We recommend that organizations migrate to Windows 10 or a supported operating system before the end of support date on January 14, 2020 in order to continue receiving new feature updates to Office 365 ProPlus. Make sure to discuss this process with your local IT staff before making changes to your system.

    We’ll be providing more information by January about how to get security updates for Office 365 ProPlus on devices running Windows 7 after support for Windows 7 ends.

    Note: This information also applies to Office 365 Business which is included in business plans such as M365 Business and Office 365 Business Premium, and to desktop versions of Project and Visio.
