What Is Office 2021?

Office 2021 is Microsoft’s one-time purchase productivity suite that includes apps like Word, Excel, PowerPoint, and Outlook. Unlike Microsoft 365, it doesn’t require a subscription and doesn’t offer continuous updates or cloud integration features like OneDrive sync or real-time collaboration.

  • Local file saving and management

Is Office 2021 Secure Without Cloud Sync?

Office 2021 is secure as a standalone product when used on a protected device. However, skipping Microsoft 365’s cloud sync introduces trade-offs you should be aware of:
