The user needs to purchase Microsoft 365 Basic or additional OneDrive storage for a child's Microsoft account but is blocked by system policies.

How to Buy Microsoft 365 Basic or OneDrive Storage for a Child Account

Product: Microsoft 365 / OneDrive
Device & OS: not provided
Scenario: Attempting to upgrade cloud storage or subscribe to Microsoft 365 Basic directly on a child's account.
Observed behavior: The purchase is blocked because Microsoft Family Safety age restrictions identify the user as too young, even when payment details and spending permissions are properly configured.

Before you start

Ensure you have the login credentials for both the child's Microsoft account and the parent or organizer account, as adult authorization may be required to finalize the transaction.

Solution 1Recommended

Complete the Purchase Through a Web Browser

Bypass potential app-level billing restrictions by processing the storage upgrade directly through the Microsoft online store.

In some cases, the OneDrive app may enforce strict mobile store policies that conflict with child accounts. Using a direct web browser link can help circumvent this issue, though core Microsoft age policies will still apply.

Log into the online portal

Open a web browser and navigate to the official Microsoft OneDrive cloud storage upgrade page (https://www.microsoft.com/en-us/microsoft-365/onedrive/online-cloud-storage). Sign in using the child's account credentials.

Select the storage plan

Under the Microsoft 365 Basic section, choose your preferred billing cycle (monthly or yearly purchase option).

Process the payment

Proceed to checkout. If prompted for adult approval due to age restrictions, sign in with the parent/organizer account to authorize the transaction.

Complete the Purchase Through a Web Browser

Persistent Age Restrictions: If the web browser purchase is still completely blocked by age restrictions, an adult account must be used to buy the subscription, or you must contact Microsoft Support for account-specific guidance.

Solution 2

Purchase via an Adult Account using Microsoft 365 Family

Use a parent account to purchase a family subscription, which can then be shared with the child account without triggering age restrictions.

Frequently Asked Questions

Can I add funds to a child's account to bypass the subscription block?

No. Even if a child's account has sufficient Microsoft account balance from gift cards or has spending permissions enabled by a parent, Microsoft Family Safety policies strictly restrict minors from entering into recurring subscription agreements directly.

How do I share OneDrive storage with my child?

You cannot share the 100 GB storage from a Microsoft 365 Basic plan. To share storage with a child, an adult must purchase a Microsoft 365 Family subscription and share the benefits via the Microsoft Family dashboard, which grants the child their own private 1 TB of storage.

Why does the OneDrive app prevent the purchase when the website might not?

In-app purchases on mobile devices are governed by both Microsoft's account policies and the mobile platform's app store policies (such as Apple's App Store or Google Play). These app stores often have stricter enforcement on minor accounts, which is why purchasing through a web browser is recommended as a troubleshooting step.
