What happens to my data from MS Project Online on 30 September 2026?
Project Web App stops loading, the OData reporting API stops responding, and your projects, timesheets and resource data go with it. Anything you have not exported before that date should be treated as gone.
Microsoft lists the retirement on its lifecycle page as 30 September 2026, 08:00 PT, under the Modern Lifecycle Policy. This is not a feature freeze, it is the end of the service, so there is no version to stay on and no extended support to buy.

Microsoft Project Online is being retired on September 30, 2026, with Microsoft shifting its strategy toward Microsoft 365-based planning tools.

Has MS Project been discontinued?
No, Microsoft Project as a whole has not been discontinued. Only the cloud-based Project Online is retiring on September 30, 2026, while the desktop version (Project Professional/Standard) and Project Server Subscription Edition continue with support.
Project Online stops new sales October 1, 2025, and fully retires in 2026 due to its outdated architecture, with Microsoft shifting focus to AI-enhanced tools like Planner Premium and Project for the web. Desktop apps remain fully supported indefinitely, and on-premises Project Server lasts until at least 2031.
