Scenario: Deleting old emails and attachments in Hotmail/Outlook via web browsers (like Chrome or Edge) to free up OneDrive storage space.

Solution 1Recommended

Clear Browser Cache and Retry the Operation

Use this solution to resolve temporary browser conflicts or corrupted cache data that might be causing the OneDrive service to stop responding.

Web browsers like Google Chrome and Microsoft Edge store temporary data that can sometimes conflict with live cloud services. Clearing this data forces the browser to fetch a fresh version of the page.

Open Browser Settings

In Google Chrome or Microsoft Edge, click the three-dot menu icon in the top-right corner and select Settings.

Clear Browsing Data

Navigate to Privacy and security (Chrome) or Privacy, search, and services (Edge). Click on Clear browsing data.

Select Cache and Cookies

Check the boxes for Cookies and other site data and Cached images and files. Choose All time for the time range, then click Clear data.

Restart and Retry

Close the browser completely, reopen it, and log back into your Hotmail or OneDrive account to attempt the deletion process again.

Clear Browser Cache and Retry the Operation

Alternative Browser: If the error persists in Chrome, try logging into your account using Microsoft Edge, or use an Incognito/InPrivate window to bypass cached data completely.

Solution 2

Verify Account Storage Status

Check if your Microsoft account has been temporarily frozen or restricted due to exceeding storage limits.

Solution 3

Report Reference Codes to Microsoft Support

If troubleshooting fails, provide the exact error values to Microsoft for a backend fix.

Frequently Asked Questions

Why does OneDrive show reference codes when I delete files?

These codes typically appear when the server encounters an unexpected sync conflict, a browser cache error, or a temporary block placed on your account when bulk-deleting items to free up storage space.

Will clearing my browser cache delete my OneDrive files?

No, clearing your browser cache only removes temporary internet files and cookies stored locally on your computer. Your actual emails, attachments, and OneDrive files remain safely stored on Microsoft's cloud servers.

What should I do if the reference code error persists across different web browsers?

If switching from Chrome to Edge doesn't resolve the issue, check your Microsoft account storage quota directly. If the account is locked or the error continues, you will need to contact Microsoft Support and provide them with the exact reference code for further assistance.
