If your organization is using Office 365 ProPlus on devices running Windows 7, we strongly recommend your organization move those devices to Windows 10.Įven 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. Using Office 365 ProPlus on older, unsupported operating systems may cause performance and reliability issues over time. This includes using Office 365 ProPlus on a Windows operating system that is currently in support. 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. As announced previously, Windows 7 will be out of support after January 14, 2020.
