How to Fix Microsoft Saying OneDrive is Over 5 GB Despite a 1 TB Plan
Question details
The user is receiving a notification that their OneDrive storage has exceeded 5 GB, even though they have an active 1 TB subscription plan.

- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Checking cloud storage limits or receiving emails about exceeded storage quotas.
- Observed behavior
- The system or email claims the 5 GB storage limit is exceeded, yet file uploads and emails continue to work normally, indicating a reporting error or a phishing attempt.
Do not click on any links in a storage warning email until you have verified it is actually from Microsoft, as this is a common phishing tactic used to steal credentials.
Verify the Authenticity of the Storage Warning Email
Confirm whether the email is a genuine Microsoft alert or a phishing attempt to steal your credentials.
If you received an email stating your storage is full, but your uploads still work perfectly, you may be the target of a phishing scam. Always verify the sender before taking action.
Check the actual email address of the sender, not just the display name. Genuine Microsoft account emails typically come from addresses ending in @accountprotection.microsoft.com.
Hover your mouse over any 'Upgrade' or 'Check Storage' buttons without clicking. Verify if the URL points to a legitimate Microsoft domain.
Instead of using email links, open your web browser, navigate directly to onedrive.com, and log in to check your actual storage status securely.

Check Your Subscription and Storage Dashboard
Ensure your 1 TB subscription is active and applied to the correct Microsoft account.
Contact Microsoft Support for Account Sync Issues
If your dashboard shows 1 TB but you still receive 5 GB limit errors, a backend sync issue requires intervention from Microsoft Support.

Frequently Asked Questions
Why did my OneDrive storage suddenly drop to 5 GB?
If your Microsoft 365 subscription expires or your recurring payment fails, your OneDrive storage allowance automatically reverts to the free tier limit of 5 GB. Check your billing status in your Microsoft account to resolve this.
Are storage warning emails from Microsoft always real?
No. Scammers frequently send fake 'storage full' emails to trick users into entering their login credentials on fake websites. Always navigate to onedrive.live.com directly instead of clicking links in these emails.
Do Outlook email attachments count towards my OneDrive storage limit?
Yes. Microsoft recently changed its storage policy so that Outlook.com email attachments now count against your total Microsoft cloud storage, which includes your OneDrive quota.
