Dear Ben,
You need the product key but are unable to access the email associated with the purchasing account. For your account's security, we cannot send a product key to a different email address. However, your key is securely stored within your Microsoft account's order history, and you can access it directly.
Please follow these steps to retrieve your key:
Go to the official Microsoft Account website: account.microsoft.com.
Sign in using the @outlook.com email address and password you used to make the purchase.
Once signed in, navigate to the "Payment & billing" section in the top menu and select "Order history."
Locate your Windows 11 Pro purchase from 10/09/25 and click on it to view the details, which will include the product key.
If you are unable to sign in because you cannot access the @outlook.com mailbox, you must use the official "Account Recovery" process on the sign-in page to verify your identity and update your security contact information. This is the most secure method to regain access to your account and purchase details.
