Processos no Microsoft 365 para configurar aplicativos do Office, resgatar chaves de produto e ativar licenças.
Hi there, Stephane! This is Marc. Thanks for reaching out to the community.
The error message TokenAlreadyRedeemedByOtherMSA means that the product key you're trying to use has already been redeemed and permanently linked to a different Microsoft account. Here are some approaches you can try.
- Double-check any other Microsoft accounts you may have used (including old ones) to redeem the key. You can sign in to https://account.microsoft.com/services on each account to see if the license shows up.
- If you purchased the key from a third party, contact the seller and request clarification or a refund especially if it was not a Microsoft-authorized reseller.
- If you believe you’re entering the correct account but still receive this error, you can contact Microsoft Support to check the activation history of the product key:
https://support.microsoft.com/contactus
Make sure to include your proof of purchase and the full error code when contacting support.
Let me know how it goes.
Best regards,
