Fix Office LTSC 2024 Product Key Already Used Error
Question details
The user is unable to activate Office LTSC Professional Plus 2024 because the system displays an error stating the product key has already been used.
- Product
- Microsoft Office LTSC 2024
- Device & OS
- not provided
- Scenario
- Attempting to activate a fresh installation of Office LTSC Professional Plus 2024 using a volume license product key.
- Observed behavior
- The activation wizard fails and returns a warning message indicating that the provided product key has already been used or reached its maximum activation limit.
Ensure you are using the correct Multiple Activation Key (MAK) or Key Management Service (KMS) key provided for your volume license agreement, and verify that the key matches your specific Office LTSC 2024 installation method.
Verify Volume License Limits and Contact Reseller
Use this solution to check if your Multiple Activation Key (MAK) has exceeded its maximum allowed activations and to request a limit increase.
Office LTSC 2024 volume licenses typically use MAK or KMS keys. A MAK key has a predetermined limit on how many times it can be used for activation. If you receive an 'already used' error, the key has likely reached this limit.
Navigate to the Microsoft 365 Admin Center or the Volume Licensing Service Center (VLSC) and sign in with your enterprise administrator credentials.
Go to the 'Billing' or 'Your Products' section, select 'Volume Licensing', and view your Office LTSC Professional Plus 2024 product key details to see the current activation count.
If the activation limit has been reached, click the 'Support' button in the admin center or contact your software reseller directly to request an increase in your MAK activation limit.
Seek Assistance in the Microsoft Q&A Community
If you are an IT administrator and cannot resolve the volume activation failure, escalate the issue to enterprise support engineers.

Frequently Asked Questions
Why does my Office LTSC 2024 MAK key say it is already used?
Multiple Activation Keys (MAK) have a strict predetermined limit on the number of allowed activations based on your enterprise agreement. If this limit is exceeded due to hardware changes or reimaging PCs, you will receive an 'already used' error and must contact Microsoft support to request an activation limit increase.
What is the difference between KMS and MAK activation for Office LTSC?
KMS (Key Management Service) activates Office locally on your network via a host server and requires client computers to reconnect every 180 days. MAK (Multiple Activation Key) activates Office directly with Microsoft's servers over the internet once, but has a hard limit on the total number of activations.
Where can I find my Office LTSC 2024 volume license key?
Volume license keys for Office LTSC 2024 are managed through the Microsoft 365 Admin Center or the Volume Licensing Service Center (VLSC). You need specialized administrative access to log in and view the product keys assigned to your organization.
Does WPS Office require a product key to open Office LTSC files?
No, WPS Office is a free-to-download software suite. It opens Microsoft Word, Excel, and PowerPoint files instantly without requiring a product key, volume license agreement, or complex activation procedures.
