    Hello Roy, good day and thanks for your question. I understand that you are looking into a lost product key for a Microsoft product or service that you have.

    Did you obtained this from your school?

    If this is for Microsoft 365 that you have purchased, there is no product key involved not unless this is an Office product or suite.

    If this is came from a school, you should be able to check or obtain the license from them if the Microsoft 365 or Office suite is not tied to the account that was created for you.

    A “Microsoft Office 365 Lifetime Subscription for Home & Student” is not a genuine Microsoft 365 offer. Microsoft 365 is a subscription service (monthly or yearly), not a one-time “lifetime” license. Offers advertised as “lifetime Office 365” are typically fraudulent or unauthorized, and their product keys are often blocked.

    For a lost or damaged genuine product key, the supported options are:

    1. If the key was genuine and you have proof of purchase
      • Microsoft support may be able to replace the product key or provide other options if there is valid proof of purchase.
      • Use the official support channel: Microsoft support.
    2. If the key does not work or has been blocked
      • If the Office product key does not work or has stopped working, contact the seller and request a refund.
      • Keys sold separately from software are often stolen or fraudulently obtained and then blocked. Microsoft recommends requesting a refund from the seller in this case.
    3. If the key was lost and cannot be recovered
      • If the product key has been lost, stolen, or misplaced and cannot be recovered, the supported path is to purchase a new, genuine license (for example, a current Microsoft 365 subscription or a one-time-purchase Office edition) from Microsoft or an authorized reseller.

    Because “Office 365 Lifetime Home & Student” is not a legitimate Microsoft product, the practical next steps are:

    • Stop using that key/source and request a refund from the seller.
    • Purchase a genuine Microsoft 365 subscription or Office one-time license directly from Microsoft or a trusted retailer, following Microsoft’s tips for safer shopping and avoiding standalone product keys sold online.
