End of Support

Office 2021 support ends on 13 October: what are your options?

On Tuesday 13 October 2026, Office 2021 gets its last update. That goes for the version you bought in a shop and for Office LTSC 2021, the version organisations buy through volume licensing [1] [2]. Microsoft leaves no opening: “there will be no extension and no extended security updates” [1].

What end of support means

Word and Excel will start on 14 October exactly as they did the day before. “All of your Office 2021 apps may continue to function. However, you could expose yourself to serious and potentially harmful security risks.” [1]
