Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Neel Kamineni,
From what you shared, the product key appears to have been redeemed using an email address you do not recognize. A key can be redeemed only once and then becomes linked to the Microsoft account used during redemption.
I recommend trying the steps below:
First, sign in to Services & subscriptions with every Microsoft account you may have used, including an older Outlook, Hotmail, Gmail, or Yahoo address. If Office appears, install it from there and activate it by signing in with that account.
If Office is not listed under any of your accounts, please contact the retailer if the key was bought from a third party and request that they check the sale or provide a replacement.
Otherwise, contact Microsoft Support and have your product key card or purchase receipt ready so they can verify the purchase and check the key’s redemption status. Since this is a user-to-user forum, we cannot access account records or identify which account redeemed the key, we can only share suggestions based on our findings and personal experiences.
Here's how to reach out to the Support Team (live chat):
- Go to: https://support.microsoft.com/home/contact

- Hit "Get Help"
- Scroll down and select Sign in to contact support for further assistance (please sign in using a personal Microsoft account). Then follow the on-screen prompts to reach Support Team.
Tip: Support chat availability may vary by country/region, product, and support hours. If you can't get in touch with a chat agent right away, trying again later or at a different time may help.
Hopefully your issue will be sorted out soon. Thank you so much for your patience!
Best regards.
