Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Check the exact edition shown in an Office app: retail Office 2024 must be redeemed to a Microsoft account, while Office LTSC Professional Plus 2024 uses organizational volume activation and is not recovered through a personal account.
1. Identify the installed license
Open Word → File → Account and read the full name under Product Information.
If it says Office Home 2024 or Office Home & Business 2024
Redeem the key separately even though activation inside the app succeeded:
- Go to https://www.office.com/setup.
- Sign in with the Microsoft account where the product should be stored.
- Enter the 25-character key without hyphens, if prompted.
- Complete every redemption prompt.
- Return to https://account.microsoft.com/services, scroll to Products you've purchased, and look for Office 2024.
Microsoft documents that this redemption associates Office 2024 with the signed-in account so future installations use that account rather than the key.^1^
If setup reports “This product key has already been used,” do not keep entering it. That means it has already been redeemed. Sign into each Microsoft account that might have been used and check Services & subscriptions; installation and reinstallation must then be performed from the account holding the license.^1^
Also preserve the purchase receipt and seller’s key record until the product appears in the account.
If it says Office LTSC Professional Plus 2024 or Office LTSC Standard 2024
Do not expect it to appear as a retail product under a personal Microsoft account. These editions are organizational volume-licensed products activated through KMS or MAK, rather than the normal retail account-redemption process.^2^
In that case:
- Obtain the installer, key record, and future reinstallation instructions from the organization or authorized volume-license seller.
- If it was advertised as a normal personal retail license, contact the seller and request the correct retail edition or a refund. Microsoft warns that separately sold keys can be unauthorized and may later be blocked.^1^
- Do not rely solely on the current “activated” status as proof that it is attached to the personal Microsoft account.
If it is retail but still missing
If the redemption completes under the intended account but Office 2024 still does not appear under Products you've purchased, contact Microsoft Support and provide the purchase receipt, seller information, exact edition from File → Account, and the account used for redemption. Do not post the product key publicly.
