Microsoft Lifecycle FAQ—Office

The Office 365 suite of services, along with Office 365 ProPlus, is governed by the Modern Lifecycle Policy. Other Office products are governed by the Fixed Lifecycle Policy. Search for a specific Office product to see its corresponding Lifecycle Policy and end-of-support dates.

For Office on-premises products released after February 1, 2018, Microsoft will provide 5 years of mainstream support with 2 years of extended support as an exception to the 10-year Fixed-Lifecycle Policy term. This 7-year term will align with the support period for Office 2016.

The Office Live Meeting service was decommissioned on December 31, 2017. Please see the Skype for Business blog for step-by-step guidance on planning and executing your transition. In addition, the Microsoft FastTrack for Office 365 provides useful resources and help for customers adopting Office 365.
