What's the difference between Office 365 and Office 2021?

The main difference between Microsoft 365 (formerly Office 365) and Office 2021 lies in their purchasing models and features:

Microsoft 365:

1. Subscription-Based: You pay a monthly or yearly fee.
2. Always Up-to-Date: Includes the latest versions of Office apps like Word, Excel, PowerPoint, and Outlook, along with regular updates and new features.
3. Multiple Devices: You can install Office on up to 5 devices per user.
4. Cloud Services: Includes 1TB of OneDrive storage, Microsoft Teams, and other cloud-based features for collaboration and productivity.
5. Additional Features: Access to premium features like Microsoft Editor and advanced security options.

Office 2021:

1. One-Time Purchase: You pay a single, upfront cost.
2. Static Version: Includes classic 2021 versions of Office apps like Word, Excel, and PowerPoint. No feature updates after purchase.
3. Single Device: Licensed for use on one PC or Mac.
4. No Cloud Services: Does not include additional cloud storage or collaboration tools.**

In summary, Microsoft 365 is ideal if you want the latest features, regular updates, and cloud services, while Office 2021 is suitable if you prefer a one-time purchase without ongoing costs.
