## Troubleshooting Common Activation Issues

– Ensure you’re connected to the internet for online activation
– Verify you’ve entered the key correctly (no spaces, correct characters)
– Check if your product key has already been used on another device
– Confirm your Office version matches the key type (Home, Professional, etc.)
– Contact Microsoft Support if issues persist
## Managing Your Office Subscription
For Office 365/Microsoft 365 subscribers:
– Your subscription is tied to your Microsoft account
– No traditional product key is needed after initial setup
– Manage your subscription through account.microsoft.com
– Ensure automatic renewal is set up to avoid service interruptions
## Important Security Considerations
Always purchase Microsoft Office keys from authorized retailers to avoid:
– Counterfeit or invalid keys
– Security risks from pirated software
– Lack of updates and support
– Potential legal consequences
Remember that sharing product keys violates Microsoft’s terms of service and may result in deactivation of your software. Each key is typically valid for one installation unless you have a volume license agreement.
