Answer 2

The error TakenAlreadyRedeemedByOtherMSA indicates that the Office/Microsoft 365 product key has already been redeemed and associated with a different Microsoft account. A product key can only be redeemed once and cannot be moved between Microsoft accounts.

To proceed:

1. If access to the Microsoft account that originally redeemed the key is available, sign in to the Microsoft account, Services & subscriptions page with that account to install or manage Office without re‑entering the key.
2. If the key was shared with someone else, they will see the same “already used” behavior; instead of sharing the key, the subscription owner must share the Microsoft 365 Family benefits using the documented sharing process so others can install from their own accounts.
3. If the key was purchased from a retailer or third party and is believed not to have been redeemed personally, contact the seller and request a refund or replacement, as the key may have been previously used or fraudulently sold.

The key itself cannot be redeemed again on a different Microsoft account.
