Before you start

Gather your purchase receipt, order confirmation number, and a valid, working email address before contacting customer support. Do not share your personal information or purchase details on public forums.

Solution 1Recommended

Contact the Third-Party Retailer (Best Buy) Customer Service

Because the purchase was made through a third-party retailer, they hold the retail purchase records and are the only ones who can update your email address and resend the key.

Microsoft Community moderators do not have access to retail purchase records or third-party transaction systems. You must reach out directly to the retailer's support team to get the product key reissued.

1
Navigate to the Contact Us page

Go to the official Best Buy Contact Us page (or the respective support page of your retailer).

2
Select Digital Purchases Support

Choose the support category for 'Digital Purchases', 'Software Downloads', or 'Order Support'.

3
Provide Order Details

Supply your order number, date of purchase, and explain that the email address on file was incomplete or incorrect.

4
Request Key Resend

Ask the customer service representative to update your contact information and resend the Microsoft 365 product key to your correct email address.

Frequently Asked Questions

Can Microsoft Community moderators resend my product key?

No. Microsoft Community moderators do not have access to retail purchase records, billing systems, or personal account details, and therefore cannot resend product keys.

What if I bought Microsoft 365 directly from the Microsoft Store?

If you purchased directly from Microsoft, your product key is automatically linked to your account as a digital license. You do not need a product key; simply sign in to the Microsoft account Services & subscriptions page to download and activate Office.

Is it safe to post my order number or email on the Microsoft Community forum?

No, you should never post personal information, order numbers, product keys, or email addresses on public forums to protect your privacy and prevent software theft.
