Office 2021 Key – Professional Plus

Office 2021 Professional Plus overview

Office 2021 Professional Plus includes Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher. It is the last generation with Publisher, the layout app many clubs and small businesses use for posters, flyers and newsletters.

Microsoft support for Office 2021 ends on 13 October 2026. After that the apps keep working and the Office 2021 key can still be activated, but no more security updates are released. For a connected workstation that opens email attachments every day, Office 2024 Professional Plus is the safer choice.

This version still makes sense if you need Publisher, want to match the version used across your office, or use the PC offline.
