Support for Office 365 ProPlus on Windows 8.1 and Windows Server 2016
Office 365 ProPlus delivers cloud-connected and always up-to-date versions of the Office desktop apps. To support customers already on Office 365 ProPlus through their operating system transitions, we are updating the Windows system requirements for Office 365 ProPlus and revising some announcements that were made in February. We are pleased to announce the following updates to our Office 365 ProPlus system requirements:
- Office 365 ProPlus will continue to be supported on Windows 8.1 through January 2023, which is the end of support date for Windows 8.1.
- Office 365 ProPlus will also continue to be supported on Windows Server 2016 until October 2025.
Office 2016 connectivity support for Office 365 services
In addition, we are modifying the Office 365 services system requirements related to service connectivity. In February, we announced that starting October 13, 2020, customers will need Office 365 ProPlus or Office 2019 clients in mainstream support to connect to Office 365 services.
To give you more time to transition fully to the cloud, we are now modifying that policy and will continue to support Office 2016 connections with the Office 365 services through October 2023.
Servicing and support flexibility

In April 2017, we aligned the Windows 10 and Office 365 ProPlus update cadence to a predictable semi-annual schedule, targeting September and March. While many customers—
Based on that feedback, we’re announcing four changes:
- All currently supported feature updates of Windows 10 Enterprise and Education editions (versions 1607, 1703, 1709, and 1803) will be supported for 30 months from their original release date. This will give customers on those versions more time for change management as they move to a faster update cycle.
- All future feature updates of Windows 10 Enterprise and Education editions with a targeted release month of September (starting with 1809) will be supported for 30 months from their release date. This will give customers with longer deployment cycles the time they need to plan, test, and deploy.
- All future feature updates of Windows 10 Enterprise and Education editions with a targeted release month of March (starting with 1903) will continue to be supported for 18 months from their release date. This maintains the semi-annual update cadence as our north star and retains the option for customers that want to update twice a year.
- All feature releases of Windows 10 Home, Windows 10 Pro, and Office 365 ProPlus will continue to be supported for 18 months (this applies to feature updates targeting both March and September).
In summary, our new modern desktop support policies—
