- Scenario
- Activating and installing a newly purchased digital Microsoft 365 Personal subscription.
- Observed behavior
- The user is unable to install or activate the software because the product key email or digital download information is missing, despite having proof of purchase.
Before contacting support, check your email's spam, junk, or promotions folders for any messages from Best Buy regarding your digital download. Additionally, gather your order confirmation number, receipt, and the email address used for the purchase.
Check Best Buy Digital Library and Contact Support
Since the purchase was made through Best Buy, they are the primary distributor responsible for providing the digital product key.
Retailers manage their own digital inventory and distribution. In most cases, missing keys from third-party purchases must be retrieved directly from the retailer's digital library or customer support system.
Log in to your BestBuy.com account, navigate to your Digital Library or Digital Purchases section, and look for your Microsoft 365 order to see if the product key is displayed.
If the key is not in your Digital Library, contact Best Buy customer service. Provide your order number and explain that the digital delivery email containing the 25-character product key was never received.

Contact Microsoft Support with Proof of Purchase
Use this solution if Best Buy is unable to assist you or if too much time has passed since the original purchase date.
Install Microsoft 365 Once the Key is Retrieved
Follow these steps to activate your subscription and download the software once you have successfully obtained your 25-character product key.

Frequently Asked Questions
Can I activate Microsoft 365 without a product key?
If you purchased a digital copy from a third-party retailer like Best Buy, you must have the 25-character product key to link the subscription to your Microsoft account. If you purchase the subscription directly from the Microsoft Store, it is automatically linked to your account and no key is required.
Where do I find my digital purchases on the Best Buy website?
Log in to your Best Buy account, click on your account profile at the top right, and navigate to the 'Digital Library' or 'Purchases' section. Digital software downloads and their associated activation keys are typically stored there.
What should I do if my Best Buy product key email was deleted?
First, check your email provider's trash or deleted items folder. If the email has been permanently deleted, log into your Best Buy Digital Library to view the key online, or contact Best Buy customer support to request that the confirmation email be resent.
