Microsoft Project Online is retiring: What you need to know

After more than a decade of supporting project managers and teams around the world, Project Online will officially retire on September 30, 2026. We know this is a significant change, and we want to acknowledge the impact it may have on your organization, your workflows, and your planning processes.

This update is exclusive to Project Online and does not affect Project desktop, Project Server, or Planner (which brings together Project for the web, Planner in Microsoft 365, and To Do).

Why this change is happening

Project Online has served organizations well, but its legacy architecture limits innovation and integration that enhance today’s collaborative work environments, as we announced in 2018. With certain SharePoint Online workflow design tools deprecating in 2026, Microsoft is prioritizing innovation within Planner, Microsoft 365 Copilot, and the Project Manager agent, which represents a new generation of work management tools designed to be more intuitive, scalable, and powered by AI. These tools are built to support both simple task tracking and complex project planning, while integrating deeply across Microsoft 365.

What this means for you

  • No immediate disruption: Your current Project Online environment will continue to function as expected until the retirement date.
  • Key dates:
    • October 1, 2025: End of sale for new customers for Project Online-only SKUs.
    • September 30, 2026: Official retirement date – Project Online will no longer be available.
  • Project desktop remains available and is not impacted by this change.
  • Planner remains available and brings together Project for the web (premium plans), Planner in Microsoft 365 (basic plans), and To Do.

Transition options

There are several transition options available, depending on your organization’s needs:

  • Planner: A unified solution for modern work and project management. Premium features in Planner (included in Planner and Project Plan 3 and Planner and Project Plan 5) deliver portfolios, baselines, dependencies, Gantt charts, and workflow automation via Power App/Accelerator and Power Automate. Premium license holders (including Project Online customers) already have access to Planner and Project desktop. Now in public preview, Planner introduces Project Manager agent for Microsoft 365 Copilot users—an AI assistant that automates task creation, status reporting, and execution, adapting to your project’s context and generating professional reports across Planner views.
  • Project Server Subscription Edition: Designed for organizations needing advanced project and portfolio management (PPM) or a close match to the feature set of Project Online. Project Server Subscription Edition provides comprehensive planning, scheduling, and resource management tools, built on the latest SharePoint Server technology.
  • Dynamics 365 Project Operations: Tailored for customers who require robust timesheet management and resource scheduling, Dynamics 365 Project Operations offers integrated tools for project delivery and financials.

How to prepare

  • This retirement will happen automatically on the specified dates with no admin action required.
  • You may want to notify your users and update any internal documentation to reflect the above changes.
  • Evaluate the alternatives proposed above and plan the transition immediately.
  • Back up your data, if needed, before the retirement date.

Looking ahead

We fully understand the challenge associated with this or any product retirement. We remain excited about the future of our Work Management solutions with enhancements coming to Planner, including advancements in AI-powered project management. With Planner and our AI-powered roadmap, we’re building a future where project management is intuitive, collaborative, and deeply integrated into the flow of work across Microsoft 365. Planner and the Project Manager agent are just the beginning of a more intelligent, integrated, and collaborative project management experience.
