## Troubleshooting Common Activation Issues

If you encounter problems during activation, try these solutions:

– Ensure you’re connected to the internet for online activation
– Verify you’ve entered the product key correctly (no dashes needed)
– Check if your product key has already been used on too many devices
– Make sure your Office version matches the product key type (Home, Professional, etc.)
– Contact Microsoft Support if you suspect your key is invalid or compromised

## Managing Your Office Product Key

After successful activation, consider these best practices:

– Store your product key securely (password manager or physical safe)
– Link your Office installation to a Microsoft account for easier management
– Keep proof of purchase in case you need to reactivate later
– Be cautious of third-party key sellers offering suspiciously low prices

## Frequently Asked Questions

### Can I use the same product key on multiple computers?

This depends on your license type. Retail versions typically allow installation on one desktop and one portable device. Volume licenses may permit more installations. Always check your specific license terms.

### What if I lost my product key?

If you purchased digitally, check your email or Microsoft account. For retail purchases without records, you may need to contact Microsoft Support with proof of purchase.

### Do product keys expire?

Generally, no. However, Microsoft may retire support for older Office versions, making activation more difficult over time.

### Can I transfer my product key to a new computer?

Yes, but you’ll need to deactivate Office on the old computer first in most cases. The process varies by license type.
