Solution 1Recommended

Cancel the Redundant OneDrive Storage Plan via Microsoft Account

Safely remove the older 100 GB or Basic plan since your Microsoft 365 subscription already covers your storage needs.

As long as both subscriptions are linked to the same Microsoft account, your files will remain safe in OneDrive under the new 1 TB storage allowance. Canceling the smaller plan will simply reduce your total combined storage by 100 GB.

Sign in to Microsoft Services

Navigate to account.microsoft.com/services in your web browser and log in using the Microsoft account associated with your active subscriptions.

Locate the 100 GB Plan

Scroll through your list of active services to find the older 100 GB OneDrive or Microsoft 365 Basic subscription.

Manage the Subscription

Click on 'Manage' next to the 100 GB plan, then select 'Cancel subscription' or 'Turn off recurring billing'.

Confirm Cancellation

Follow the on-screen prompts to finalize the cancellation. Afterward, check your OneDrive storage gauge to ensure you still have 1 TB available from your primary Microsoft 365 plan.

Frequently Asked Questions

Will I lose my files if I cancel the 100 GB OneDrive plan?

No. As long as your new Microsoft 365 subscription (which includes 1 TB of storage) is active on the same account, your files are protected under the larger storage limit.

Why does my OneDrive show combined storage capacity?

Microsoft stacks storage when you have multiple active plans on the same account. Upgrading to Microsoft 365 while keeping the 100 GB plan active will show as 1.1 TB until the smaller plan is officially canceled or expires.

Can I get a refund for the unused portion of my 100 GB plan?

Depending on your region and when you purchased or renewed the plan, Microsoft may offer a prorated refund upon cancellation. You will see any available refund options during the cancellation process on the Microsoft account services page.

What happens if I cancel the wrong Microsoft subscription?

If you accidentally cancel your 1 TB Microsoft 365 plan instead of the 100 GB plan, your files will become read-only once the billing cycle ends. You can easily fix this by logging back in and turning recurring billing back on before the cycle concludes.
