Fix OneDrive Showing Different Storage Limits on Web and Desktop
Question details
The user needs to resolve a storage capacity discrepancy where the OneDrive desktop app shows a lower limit than the web version, causing syncing issues and halting email delivery.

- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Monitoring cloud storage usage and syncing local desktop files to the cloud.
- Observed behavior
- The OneDrive desktop client reports being over quota (e.g., 8.5 GB of 5 GB used), while the web version correctly shows a higher limit (e.g., 10.4 GB of 15 GB) due to a loyalty bonus. This mismatch halts file synchronization and blocks new Outlook email delivery.
Log in to OneDrive.com to verify your actual storage quota and manually back up any important local files to a separate folder or external drive before altering your desktop client settings.
Unlink and Relink Your OneDrive Account
Refreshing the connection between your computer and OneDrive forces the desktop client to fetch the most up-to-date storage quota from the web servers.
Often, a simple account synchronization bug causes the desktop app to forget extra storage entitlements, such as a Loyalty Bonus. Re-authenticating your account clears this glitch without deleting your local files.
Click the OneDrive cloud icon in your taskbar or menu bar, click the gear icon for Help & Settings, and select 'Settings'.
Navigate to the 'Account' tab and click the 'Unlink this PC' link.
After the client unlinks, the OneDrive setup screen will appear. Enter your Microsoft account credentials to sign back in and re-establish the connection.

Reset the OneDrive Desktop Client
Resetting the OneDrive app clears its cache and resolves persistent background bugs that prevent it from recognizing loyalty bonuses.
Temporarily Upgrade Storage to Unfreeze Account
If the discrepancy is caused by a Microsoft server-side bug affecting email delivery, a temporary upgrade can restore functionality while you contact support.

Frequently Asked Questions
Why did my OneDrive Loyalty Bonus disappear on the desktop client?
This is generally caused by a synchronization bug in the OneDrive desktop client. While your Microsoft account server retains the bonus (visible on the web), the local app fails to fetch the correct data and defaults to the base storage limit.
Will uninstalling OneDrive fix the storage limit mismatch?
Uninstalling OneDrive is highly discouraged as a first step. Completely removing the application can delete local files that were blocked from syncing due to the storage error. Always try unlinking the account or resetting the client first.
How can I check my true OneDrive storage limit?
Log in to your account at OneDrive.com and check the storage metrics page. The web dashboard always displays your actual, server-side storage quota, including any active bonuses or promotional space.
Can OneDrive storage limits block my Outlook emails?
Yes. Microsoft shares your cloud storage quota across both OneDrive files and Outlook email attachments. If OneDrive believes you are over your storage limit, it will freeze both file syncing and your ability to send or receive emails.
