Question details

The user is unable to create new files in Microsoft 365 applications and cannot access OneNote notebooks, even though their OneDrive account shows minimal storage usage.

Product: Microsoft 365
Device & OS: not provided
Scenario: Creating new documents and accessing synced OneNote notebooks.
Observed behavior: Microsoft 365 apps block file creation and restrict access to OneNote notebooks, presenting symptoms of a full storage quota despite adequate space remaining.

Before you start

Ensure you are logged into the correct Microsoft account associated with your active Microsoft 365 subscription, and verify your internet connection is stable.

Solution 1Recommended

Verify Subscription and Storage Quota via OneDrive Web

Check your actual storage quota on the web version of OneDrive and verify your subscription status to rule out desktop syncing or display errors.

Log into OneDrive Web

Go to the official OneDrive website in your browser and sign in using the Microsoft account credentials linked to your Microsoft 365 apps.

Check Storage Metrics

Click on the gear icon in the top right corner to open 'Settings', then select 'Options' and navigate to 'Manage storage' to view your accurate, server-side storage quota.

Verify Microsoft 365 Subscription

Navigate to your Microsoft Account dashboard, click on the 'Services & subscriptions' tab, and confirm that your Microsoft 365 plan is currently active and not expired.

Solution 2

Contact Microsoft Support for Account-Level Review

If your storage appears low on the web but file creation is still blocked, Microsoft Support needs to perform a backend quota sync or reset.

Frequently Asked Questions

Why does Microsoft 365 say my storage is full when it isn't?

This is often caused by a syncing error between your desktop apps and Microsoft's servers, or an expired subscription that temporarily reduces your allowed OneDrive quota to the 5GB free tier.

Can I still access my OneNote files if my OneDrive storage is frozen?

If your account is frozen due to a storage quota issue, you will be able to view your OneNote notebooks in read-only mode on the web, but you cannot edit them or create new ones until the issue is resolved.

How long does it take for Microsoft storage to update after deleting files?

It can take up to 24 to 48 hours for Microsoft's servers to completely process deleted files and reflect the updated storage quota across all Microsoft 365 apps.

Does email storage count towards my OneDrive limit?

Yes, Microsoft recently updated their storage policy so that Outlook.com email attachments and inline images now count against your overall Microsoft cloud storage (OneDrive) limit.
