Body (from Message Center)

Updated March 16, 2026: We have temporarily disabled the automatic installation of the Microsoft 365 Copilot app to eligible devices with the Microsoft 365 desktop apps. We will provide another update once we re-enable these installations.

Introduction

Starting in December 2025, Microsoft will begin automatically installing the Microsoft 365 Copilot app on Windows devices that have Microsoft 365 desktop client apps. This app provides a centralized entry point for accessing Copilot experiences and AI-powered capabilities across Microsoft 365. This change simplifies access to Copilot and ensures users can easily discover and engage with productivity-enhancing features.

When this will happen

Rollout begins in early December 2025 (previously early October) and completes mid-December 2025 (previously mid-November)
