Buy a Microsoft 365 subscription while signed in with the same personal Microsoft account used by OneDrive on your Samsung computer.
Purchase more OneDrive storage
- Open the Microsoft cloud storage page.
- Select Sign in.
- Sign in with the Microsoft account connected to OneDrive on the computer.
- To identify it, select the OneDrive cloud icon on the Windows taskbar, then Help & Settings → Settings → Account.
- In the Microsoft storage section, review your current usage and select Buy now.
- Choose a subscription and complete the purchase. Microsoft documents this account-dashboard purchase process here: ^1^
Typical personal options include:
- Free: 5 GB
- Microsoft 365 Basic: 100 GB for one person
- Microsoft 365 Personal: 1 TB for one person
- Microsoft 365 Family: For new subscriptions started on or after October 8, 2026, 2 TB shared among up to six people
Current tiers and any future changes are listed in Microsoft’s storage-quota table.^2^ Microsoft 365 Basic is usually the simplest choice when only 100 GB is needed; it does not include the full desktop Office applications.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Frequently asked questions about Microsoft 365 Basic | Microsoft Support")
The new quota can take up to 24 hours to appear. If it has not updated after 48 hours, contact Microsoft Support using the link in the storage-quota page.^2^
This purchase increases OneDrive cloud storage, not the physical storage drive inside the Samsung computer.
