Question details

The user wants to purchase and apply an additional 1 TB of OneDrive storage to a specific family member's account under a shared Microsoft 365 Family subscription.

Product: Microsoft 365 Family / OneDrive
Device & OS: not provided
Scenario: A user purchased extra OneDrive storage, but the entitlement was automatically applied to the primary purchaser's account rather than the intended family member's account.
Observed behavior: The additional OneDrive storage defaults to the purchaser's Microsoft account and cannot easily be reassigned to another individual sharing the Family plan.

Before you start

Ensure you know the exact Microsoft account email address of the family member who needs the additional storage, and verify they are correctly added to your Microsoft 365 Family sharing group.

Solution 1Recommended

Verify Separate Microsoft Accounts for Each Family Member

Ensure the family member is using their own independent Microsoft account rather than sharing the purchaser's account, which causes storage upgrades to apply to the wrong profile.

Microsoft 365 Family allocates a strict 1 TB of storage per user account. If family members share a single login, any additional storage purchases will only stack on that primary account.

Sign out of the primary account

On the family member's device, log out of OneDrive and any Office applications that are currently signed in with the primary purchaser's Microsoft credentials.

Sign in with a unique account

Open OneDrive and sign back in using the specific family member's unique email address and password.

Check current storage limits

Right-click the OneDrive icon in the system tray, select 'Settings', and check the 'Account' tab to confirm they have access to their base 1 TB Family allocation.

Solution 2

Purchase Additional Storage Directly from the Target Account

To guarantee extra storage applies to the correct person, the purchase must be made while logged into that specific family member's account.

Frequently Asked Questions

Can I manually transfer my purchased OneDrive storage to a family member?

No, Microsoft currently does not allow you to manually transfer or pool storage quotas between different Microsoft accounts. Additional storage purchases are strictly tied to the account that initiated the transaction.

Why does my wife's OneDrive show my files after I upgraded her storage?

This happens if she is signed into the OneDrive application on her device using your primary Microsoft account credentials instead of her own independent account. Ensure she logs out and signs back in with her own email.

How much additional OneDrive storage can a single Microsoft 365 Family member buy?

Subscribers can purchase additional OneDrive storage in increments up to an additional 1 TB. Combined with the base 1 TB provided by the Family plan, an individual account can have a total maximum storage of 2 TB.
