Microsoft Project Online will be discontinued in September 2026: how to protect your project data and prepare for the transition.
Many organisations rely on Microsoft Project Online to manage portfolios, resources and reporting across critical projects. With Microsoft confirming its retirement in September 2026, this dependency creates a concrete risk: loss of access to project data that supports governance, compliance and decision‑making.
This change affects IT leaders, PMOs and business stakeholders who depend on reliable project information. This article explains what the retirement means in practice, which data and processes are at risk, and how organisations can start preparing a structured transition to protect continuity and future project management needs.
A familiar moment
Projects are running. Plans are complex but under control. Reporting works as expected. Then someone asks the question: will Microsoft Project Online still be available next year? The answer is clear. No. Project Online will officially retire on September 30 2026.
That date may feel distant. For organizations relying on project data, governance and reporting, it is closer than it seems.
Why this matters now
Microsoft has clearly confirmed the retirement of Project Online. After the retirement date, access to the platform and its data will no longer be possible. This is not a minor product update. It is the end of a platform that has been central to project and portfolio management for years. Microsoft explains the decision by the limitations of the current architecture and a strategic shift toward Planner, Copilot and AI powered work management.
What Microsoft has officially announced
Based on Microsoft’s communication, the Project Online remains fully supported until September 30 2026 . End of sale for Project Online only licenses for new customers from October 2025.
From April 2026 existing customers can no longer create new Project Online tenants, after September 2026 projects and data will no longer be accessible. Project desktop, Project Server Subscription Edition and Planner are not impacted. Microsoft states explicitly, “After Project Online is retired, you will no longer be able to access your projects or any associated data within the service.”
The real impact is on data and processes
For many organizations, Project Online is more than a scheduling tool. It contains historical project data resource and capacity planning information portfolio and management reports integrations with Power BI and SharePoint Losing this data creates operational and strategic risk. A successful transition takes time. It requires clear choices about what to migrate, what to redesign and how teams will work going forward.
The transition paths Microsoft proposes
Microsoft outlines three main options.
Planner is becoming the central work and project management platform in Microsoft 365. Premium licenses include dependencies, baselines, Gantt views and portfolio management.
The new Project Manager agent with Copilot adds AI driven support for task creation, reporting and execution.
At Inetum, we see Planner today as the most future ready choice for the majority of organisations. Not only because Microsoft is clearly investing in it, but above all because Planner is integrated into the daily working environment of teams. In Microsoft Teams, in Microsoft 365, where collaboration actually happens today. This makes adoption more realistic and more sustainable than with standalone project tools.
Project Server Subscription Edition
A strong option for organizations with advanced PPM needs and a close functional match with Project Online.
Dynamics 365 Project Operations
Designed for organizations that need tight integration between projects, resources, time tracking and financials. There is no one size fits all answer. The right choice depends on your context and ambitions.
What you can do next
To avoid last minute pressure, these are the steps to start with now.
- Review how Project Online is used today
- Identify critical data and reporting needs
- Map users roles and dependencies
- Compare target platforms based on real use cases
- Plan migration and adoption realistically
