ℹ️ Good to know before you buy
Microsoft's support for Project 2021 ended on October 13, 2026. Project 2021 keeps working and can still be activated, but no longer receives security updates. On a budget? See Project 2019 Professional. Project is a separate app: it's not included in any Office suite.
