Microsoft Office

This category covers genuine Microsoft Office license keys — Office 2021, Office 2019, and Microsoft 365, in both Home & Business and Professional Plus editions — delivered by email within minutes of purchase. Each key activates the real Microsoft Office desktop apps (Word, Excel, PowerPoint, Outlook and more) directly through the Office activation wizard, using Microsoft's own licensing servers. Office 2021 and 2019 are one-time purchases with no subscription; Microsoft 365 keys activate a subscription plan. As a Certified Microsoft Partner and Authorized Microsoft Reseller, MCAKey sources every key through legitimate Microsoft channels. We sell single-PC licenses for individual buyers and multi-seat licenses for businesses and PC repair shops activating several machines from one order. If you're unsure which Office edition matches the apps or seat count you need, check the product description on each listing before buying — it lists the exact apps and PC count included.
