- Scenario
- Reviewing cloud storage limits and allocations after purchasing a Microsoft 365 Basic subscription.
- Observed behavior
- The account interface displays 125 GB of available storage instead of the standard 100 GB, likely combining the new subscription quota with older, account-specific storage bonuses.
Before reaching out to support, log into your OneDrive account via a web browser and check the 'Manage Storage' page to see a detailed breakdown of your current subscription quotas and promotional bonuses.
Contact Microsoft Support to Verify Account Allocation
Because legacy storage bonuses and loyalty promotions are highly account-specific, you need to contact Microsoft Support directly to verify exactly what makes up your 125 GB limit.
Microsoft 365 Basic officially includes 100 GB of cloud storage. If your account shows 125 GB, it is usually because an older 25 GB legacy bonus (often granted to early adopters) has been stacked on top of your new subscription.
Since this is an account-level calculation, community forums cannot view your data. A Microsoft support representative can review your account history and clarify your exact storage benefits.
Go to the official Microsoft account management page in your web browser and sign in with the credentials associated with your Microsoft 365 Basic subscription.
Click on the 'Help' or 'Support' section located in the top navigation bar or at the bottom of the account dashboard.
Open a support ticket or start a live chat. Ask the representative to review your account's previous storage benefits and confirm what limit will apply if you ever decide to cancel your current subscription.

Frequently Asked Questions
Why do I have 125 GB instead of the standard 100 GB in Microsoft 365 Basic?
Microsoft 365 Basic officially provides 100 GB of OneDrive storage. The extra 25 GB you see is typically a legacy bonus, such as an early-adopter or loyalty promotion, that was granted to your specific Microsoft account in the past and stacks with your new subscription.
What happens to my extra OneDrive storage if I cancel my subscription?
If you cancel Microsoft 365 Basic, your storage will revert to the free tier limit (usually 5 GB) plus any permanent legacy bonuses associated with your account. If your account holds a permanent 25 GB bonus, your post-cancellation limit will likely become 30 GB total.
Where can I see exactly where my bonus storage came from?
You can view this by logging into OneDrive on the web, clicking the Settings gear icon, selecting 'Options', and then navigating to 'Manage Storage'. This page will list your base storage and any active bonuses by name.
