Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello,
Since the product key was never redeemed, the Microsoft 365 subscription has not yet been connected to a Microsoft account. Therefore, you will not be able to recover it throughMicrosoft.
Your first step should be to contact JB Hi-Fi or return to the store where you purchased it. Provide the receipt number and any other transaction details. JB Hi-Fi should be responsible for assistance for lost digital receipts and previous in-store purchases, especially if they are legitimate authorized resellers; they do get product support from Microsoft via internal partner access. I did see on their website that they have digital receipts, so that means they should have a receipt copy.
