Request a refund from Groupon because the supplied key is for the volume-licensed Office LTSC Professional Plus 2024 edition and cannot activate a consumer/retail Office installation.
What the message means
Office LTSC Professional Plus 2024 is deployed and activated within organizations using volume licensing. Its volume keys cannot be used with retail editions such as Office Home, Home & Business, or Professional.^1^
This is not normally resolved by repeatedly entering the key or changing Microsoft accounts. Microsoft advises contacting the seller and requesting a refund when an Office key does not work; separately sold keys may be unauthorized or blocked.^2^
Recommended consumer resolution
- Save evidence
- Groupon order confirmation and listing.
- The product name advertised.
- The complete error message.
- Do not publish or send screenshots showing the full product key except through the seller’s secured support process.
- Contact Groupon or the marketplace seller
- State that the supplied key is identified by Microsoft Office as an Office LTSC Professional Plus 2024 volume-license key.
- Request a refund because it cannot activate the consumer Office installation that was sold to you.
- If necessary, use the purchase platform’s dispute process.
- Replace it with a consumer license
- Purchase Office 2024 or Microsoft 365 through Microsoft or an authorized retailer.
- For a new consumer purchase with a key, redeem it at
https://www.office.com/setup or https://microsoft365.com/setup, sign in with the Microsoft account that should own the license, and follow the installation prompts.^2^
- Remove the mismatched Office installation before installing the replacement
- In Windows, open Settings → Apps → Installed apps.
- Find the existing Microsoft Office installation, select its menu, and choose Uninstall.
- Restart Windows, then install Office from the Microsoft account associated with the legitimate replacement purchase.
Only if this purchase belongs to an organization
If your employer or organization has a valid Microsoft volume-licensing agreement and issued this key, contact its licensing administrator instead of Groupon. The administrator must deploy the matching volume edition—product ID ProPlus2024Volume—with the Office Deployment Tool and activate it using the organization’s MAK or KMS method.^3^
For MAK activation, Microsoft documents placing the MAK in the Office Deployment Tool configuration used to deploy Office LTSC 2024.^4^ This organizational path applies only when the key is covered by the organization’s volume-license agreement; installing the volume edition does not legitimize a separately resold consumer key.
