Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello, thank you for reaching out to Microsoft Q&A.
According to the Microsoft Office software licensing terms, you cannot transfer a digital license like Office from one Microsoft account to another. In some limited cases, Microsoft Support may be able to help you transfer the license.
However, in your situation it appears you no longer have access to the Microsoft account where you activated Office by mistake, and you do not have the password or recovery email to regain access. Because of this, your best option is to contact Microsoft Support directly and ask them to cancel the purchase and issue a refund, explaining that the product is new and did not meet your expectations. Once they approve and process the refund, you can repurchase Office and activate it under the correct account.
