Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
If the product key redemption failed because billing card details could not be registered, this matches the Microsoft 365 setup error "Sorry, we can't set up your account right now" (ConversionBlockedSubscriptionViolations).
To resolve it:
- Go to the Microsoft account, Payment & billing page.
- Find the Pay settings section.
- Select Change how you pay or Fix how you pay.
- Correct the billing issue on the account.
- After the billing issue is fixed, try redeeming the product key again.
If the key is for Microsoft 365 and an app is prompting for a product key after purchase, Microsoft 365 normally uses the Microsoft account used to buy it, not the product key, for install and activation.
