## Frequently Asked Questions

### Can I reuse my Office product key?

Retail keys can typically be transferred to new devices, while OEM keys are tied to the original hardware. Always check Microsoft’s licensing terms for your specific product.

### What if I lost my product key?

If you purchased digitally, check your Microsoft account or email receipt. For retail purchases without a record, you may need to purchase a new license.

### How long does activation last?

Once activated, Office remains functional indefinitely for perpetual licenses. Office 365 subscriptions require periodic verification of your active subscription status.
