Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi @Jeffrey C
Thank you for posting your question in the Microsoft Q&A forum.
Based on the information you shared, I understand that you purchased Office for Mac using an education discount and originally received a PIN via an email account that you no longer have access to. After replacing your Mac, you were able to reinstall the software but cannot activate it because you no longer have the PIN.
From what I could find, Microsoft normally does not send a product PIN or activation key to a different email address that is not associated with the original purchase or Microsoft account. For security and licensing reasons, product keys are typically tied to the original account or order information used at the time of purchase.
To better understand your situation and help you further, could you please provide a bit more information?
- Which exact product did you purchase (for example: Office for Mac 2021, Office 2019 for Mac, etc.)?
- When you sign in with the Microsoft account you used for the purchase, what message or screen do you see?
- Do you still have any proof of purchase or order confirmation?
Once we have a bit more detail about the product and what appears during activation, it will be easier to determine the best next steps.
Thank you, and I appreciate your patience.
