Microsoft Office Professional Plus 2021, 1 PC, Lifetime License

Office Professional Plus 2021: every app, including Publisher

Office Professional Plus 2021 includes the full range of Office apps for Windows, with one perpetual license for one computer. It is the last Professional Plus edition that still includes Publisher, which Microsoft retired from Office 2024.

What it includes

• Word, Excel, PowerPoint with real-time co-authoring, dynamic arrays and the XLOOKUP function in Excel.
• Outlook for email and calendar.
• Access for databases.
• Publisher for brochures, invitations, newsletters and print materials.
• OneNote for notes.

Before you buy: support

Microsoft ended security updates for Office 2021 in October 2026. The apps keep working normally, but they will not receive new fixes. We recommend Office 2021 mainly if you:

• need Publisher for existing files,
• want to match other office computers already running 2021,
• are looking for the most affordable full edition for use without heavy email.

For a new installation with long-term support, we recommend Office LTSC Professional Plus 2024.

System requirements

• Windows 10 or Windows 11
• 1.6 GHz dual-core processor, 4 GB RAM
• 4 GB free space and a 1280x768 display

Delivery and activation

1. After payment you receive the key and installation instructions by email.
2. Install Office from the official Microsoft installation package for this version.
3. Open any app and enter the key under File > Account > Change Product Key. Activation happens online.
