No product key

Question

I purchase Microsoft office but never received the product key

Answer 1

If you purchased a Microsoft Office licence or Microsoft 365 subscription directly from Microsoft, that is a digital licence associated to your account online, log into your Microsoft account online and you can install Office from there and even in the future, if you get a new PC you will not need a product key, you can install Office on a new device from there also.

Answer 2

If no product key was received from the iStore purchase, the next steps depend on how Office was supplied:

1. If Office was preinstalled on the device or tied to a Microsoft account:
   • Go to the Microsoft account dashboard for Services & subscriptions: https://account.microsoft.com/services
   • Sign in with the same Microsoft account used (or provided) when setting up Office.
   • If the Office product appears there, select it and use the Install option; no product key is needed because activation is tied to the account.
2. If a one-time purchase or card with a key should have been provided but was not:
   • Check the purchase receipt and any email from the iStore (including junk/spam folders) for a product key or instructions.
   • If the purchase was digital, the key is typically in the email receipt or in the store account’s order details.
3. If the key truly was never provided:
   • Contact the seller (iStore) directly and request the missing product key or a refund. Official guidance is that if a product key does not work or is missing, the seller must resolve it or refund the purchase.

If the seller cannot resolve the issue and the key turns out to be invalid or blocked, a new, genuine Office or Microsoft 365 license will be required.
