About Office 2021 Professional Plus
Office 2021 Professional Plus gives you the classic Office desktop apps for a single payment: Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher. There is no subscription, and it's the lowest-cost way to get full Office on a Windows PC.
It is the last one-time-purchase Office that still includes Publisher, which makes it a good fit if you rely on Publisher for flyers, newsletters or print layouts. Excel gained dynamic arrays and XLOOKUP in this release, and all apps support dark mode.
Please note: Microsoft ends security updates for Office 2021 on October 13, 2026. The apps keep working after that date, but they no longer receive security fixes. If you want Office for the long term, Office 2024 Professional Plus is supported until 2029.
