ℹ️ What is an Online Activation Key?

An Online Activation Key activates Office 2021 Pro Plus on a single Windows PC via Microsoft’s servers. If you reset or reinstall Windows on that same machine, you can activate again on that device.

• One device only: license is for a single Windows computer
• Reinstall support: reuse on the same PC after reset/clean install
• Not account-bound: different from a Bind Key (doesn’t link to your Microsoft account)

📦 Applications Included

• Word 2021 — create professional documents with advanced formatting, templates, Track Changes, PDF export, and real-time collaboration for students, businesses, and professionals.
• Excel 2021 — perform financial analysis, budgeting, and data modeling with powerful functions, dynamic arrays, PivotTables, and rich charts.
• PowerPoint 2021 — craft modern, interactive presentations with Morph, Zoom, Presenter View, and high-quality video export.
• Outlook 2021 — manage email, calendars, tasks, and contacts efficiently across devices with Focused Inbox and improved search.
• Access 2021 — create and manage relational databases with tables, forms, queries, and reports (Windows only).
• Publisher 2021 — design brochures, flyers, newsletters, and marketing materials using professional templates (Windows only).
• OneNote 2021 — organize class notes, ideas, and projects with sections, tags, ink annotations, and cross-device sync.
• Skype for Business / Teams classic — communication and video-conferencing support for organizations.
