My account shows the free Microsoft 365 plan with 120 GB of cloud storage

Open OneDrive’s Manage storage page while signed in to the affected personal Microsoft account; it shows the plans and bonuses that make up the displayed 120 GB allocation.^1^

Check the storage breakdown

1. Sign in at OneDrive Manage storage.
2. Confirm that the email address shown belongs to the account reporting 120 GB.
3. Review the entries under the storage total. Look for labels such as:
   • Free storage
   • Subscription storage
   • Samsung bonus
   • Promotional or loyalty bonus
4. Open Plans and upgrades to check whether any paid storage plan or subscription is attached to the same account.
5. Also review Microsoft Services & subscriptions for an active or recurring subscription.

The standard free allowance is 5 GB. The separate 15 GB Outlook.com mailbox allowance is not additional OneDrive capacity, so it does not explain a OneDrive total of 120 GB.^2^

What may provide the extra 115 GB

Microsoft does not document 120 GB as a standard current free plan, and the total alone is insufficient to identify its components. It is likely an aggregate of separate legacy or promotional allocations, but the Manage storage breakdown is authoritative for this particular account.

One documented possibility is a 100 GB Samsung bonus or another promotion. Microsoft states that such promotional storage can expire and cannot necessarily be renewed.^3^ However, a Samsung bonus would account for only part of the extra 115 GB; do not assume that is the source unless it is named in the account’s storage breakdown.

If the breakdown specifically says Samsung bonus, Microsoft documents that:

• The offer is limited-term.
• A notification appears before it expires.
• The storage remains associated with the Microsoft account for the offer’s remaining term, even if the original device is sold, lost, or replaced.
• Each Microsoft account can redeem the bonus only once.^4^

If no expiry date is displayed

Take a screenshot of the Manage storage breakdown and contact OneDrive support using Contact Microsoft Support on the OneDrive support page. Ask support to identify:

• Each quota component and its amount
• The promotion or entitlement that created it
• Its activation and expiration dates
• The quota that will remain after expiration

Avoid relying on the 120 GB indefinitely until its source is confirmed. If a promotion or subscription expires and usage exceeds the resulting quota, OneDrive can stop uploads, edits, and synchronization; continued over-quota status can eventually freeze the account.^3^
