How to Fix SharePoint Library Name Change Not Updating

Maira Mehtab Sep 21, 2026 868 views

Question details

After renaming SharePoint libraries, the new name only appears in the side panel while the old name remains at the top, and some libraries appear to have missing data.

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Renaming existing document libraries within a SharePoint site.
Observed behavior: The library name update is inconsistent across the user interface, and there is an apparent loss of data or missing files within the affected libraries.

Before you start

Pause any ongoing reorganization, bulk renaming, or file migrations in your SharePoint environment to prevent further indexing conflicts or data visibility issues.

Solution 1Recommended

Open a Support Ticket via Microsoft 365 Admin Center

Use this solution if you have administrative privileges to get Microsoft Support to investigate the backend synchronization and apparent data loss.

Because the SharePoint library name is displaying inconsistently and data appears to be missing, this indicates a backend synchronization or caching failure within the tenant. Microsoft Support has the necessary backend access to resolve indexing anomalies.

Access the Admin Center

Navigate to Help & Support

Click on the 'Support' tab in the left-hand navigation menu, then select 'Help & support'.

Describe the Issue

Type a brief description of the issue (e.g., 'SharePoint library name not updating and missing data') and press Enter. Review the automated suggestions, then click 'Contact support' at the bottom if the issue remains unresolved.

Provide HAR Logs

When contacted by a Microsoft support agent, be prepared to collect and provide HAR (HTTP Archive) logs from your browser to help them investigate the network requests causing the inconsistent naming.

HAR Log Collection: You can generate a HAR log by pressing F12 to open your browser's Developer Tools, navigating to the Network tab, reproducing the issue by loading the SharePoint library, and clicking 'Export HAR'.

Solution 2

Escalate to Your IT Administrator

Use this approach if you are an end-user without Microsoft 365 administrative privileges.

Frequently Asked Questions

Why does my SharePoint library show two different names?

This usually happens due to caching delays or backend synchronization issues within Microsoft 365 servers. The side panel may update immediately, while the header metadata takes longer to process.

Can changing a SharePoint library name cause permanent data loss?

Renaming a library typically only changes its display name and URL, not the underlying data. Files appearing to be missing are usually due to indexing disruptions or view settings failing to load properly.

How long does it take for a SharePoint name change to fully propagate?

While display name changes usually apply immediately, server delays or search indexing can sometimes cause it to take up to 24 hours to reflect globally across the entire tenant.

What is a HAR log and why does Microsoft Support need it?

A HAR (HTTP Archive) log records the interaction between your web browser and a website. Microsoft Support uses it to trace network errors, slow loading times, and failed API calls when SharePoint fails to load data correctly.
