Activates on 1, 3, or 5 Windows PCs depending on the option you select. No subscription, no expiry, no recurring fees.
Installed Word and Excel on all three of my PCs without a hitch. Each device activated in under five minutes using the same key. This is exactly what I needed for our small business.
Excel 2024 has new data-analysis functions that our old Office 2016 was missing. The upgrade was long overdue and the lifetime license means I never have to think about renewals again.
Switched from a Microsoft 365 subscription to this lifetime license and saved a lot over three years. PowerPoint loads faster and the AI design suggestions are genuinely useful.
The key arrived in my inbox within minutes. Activation was straightforward — log in to setup.office.com, paste the key, download the installer. Word and Outlook were running within 20 minutes.
Office 2024 Home and Business for Mac works perfectly on my MacBook Pro. Word formatting matches what my Windows colleagues send me, and Outlook syncs with our Exchange server without any issues.
