Frequently Asked Questions

Why didn't I get a product key with my Microsoft 365 purchase?

Microsoft 365 subscriptions are now issued as digital licenses tied directly to your Microsoft account. This streamlines the installation process and eliminates the need for a physical 25-character product key.

Can I activate Microsoft 365 without logging into a Microsoft account?

No. Because the subscription is tied to a specific account, you must log in with the associated email and password to verify your digital license and activate the software.

What should I do if my subscription isn't showing up in my Microsoft account?

First, verify that you are logged into the correct Microsoft account used for the purchase. If you bought it from a third-party retailer, check your email or receipt for a redemption link, or contact the seller's support for assistance.
