Microsoft closes the book on Publisher and unplugs Project Online
Office 2021 joins the October retirement list as customers weigh pricier alternatives
Microsoft is set to discontinue Project Online and retire Publisher from Microsoft 365 subscriptions over the coming weeks. Project Online, a cloud-based project management service, will end on September 30, followed by the end of support for perpetual versions of Publisher and Office 2021 on October 13. Project Online Essentials, a more affordable licensing option, will also reach end of life on October 1, 2026.
Microsoft recommends migrating users to Planner Plan 1 or Planner and Project Plan 3, but third-party alternatives like ProjectLibre are also available. Organizations must transfer affected users to supported alternatives before October 1 to maintain uninterrupted access, as Microsoft will not offer an Extended Security Updates program for Office 2021 after its support ends.
