My Onedrive Storage wasnt allocated after i have purchased Microsoft Office 365

Purchased OneDrive storage can take up to 24 hours to appear, so verify the subscription and OneDrive are using the same Microsoft account, then check the online storage quota.

Check the subscription and storage

1. Sign in to Services & subscriptions at https://account.microsoft.com/services using the Microsoft account used for the purchase.
2. Confirm that:
   • The Microsoft 365 subscription appears.
   • Its status is Active.
   • The signed-in email address matches the account used in OneDrive.
3. Open Manage your OneDrive storage with that same account.
4. Refresh the page and check whether the purchased allowance is displayed.

Microsoft states that a newly purchased subscription or storage allowance can take up to 24 hours to become visible.^1^

If OneDrive is signed in with another account on Windows:

1. Select the OneDrive cloud icon in the taskbar.
2. Select Help & Settings → Settings → Account.
3. Check the displayed email address.
4. If it is not the purchasing account, choose Unlink this PC, then sign in with the correct account. Unlinking does not delete files stored online, but allow synchronization to finish first.

If it still has not updated

• Less than 24 hours since purchase: wait until the activation window has passed and refresh the online Manage Storage page.
• More than 24 hours: check whether the subscription is visible under Services & subscriptions and whether the correct account is selected.
• More than 48 hours with an active subscription: contact Microsoft Support so the OneDrive entitlement can be checked and provisioned. Microsoft’s storage guidance specifically recommends contacting support when the quota has not updated after 48 hours.^2^

When contacting support, select Microsoft 365 → Manage my subscription and provide the purchase/order number. Do not post the order number or account details in this public forum.

If this is Microsoft 365 Family

The subscription owner must share the subscription with the intended family member; merely belonging to a Microsoft family group does not establish that the member is using the purchased subscription. Also verify that the affected OneDrive account is the account that accepted the sharing invitation. Microsoft 365 Basic and Personal storage cannot be shared.^2^
