[Introduction]
Project Online will be retired on September 30, 2026. As part of this retirement process, starting April 1, 2026, we're making changes to Project Web App (PWA) site creation and access. These changes support a smooth and predictable retirement experience, reduce unused resource consumption, and help organizations transition to modern project management solutions in Microsoft 365.
[When this will happen]
These changes will take effect starting April 1, 2026, and will remain in effect as part of the Project Online retirement process.
