Fix SharePoint New Experience Not Working in Microsoft Edge
Question details
The user needs to fix an issue where SharePoint fails to load the New Experience in Microsoft Edge, instead reverting to Classic mode or Quick Edit, despite functioning correctly in Firefox.

- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Accessing and viewing SharePoint document libraries using the Microsoft Edge browser.
- Observed behavior
- SharePoint displays the modern New Experience in Firefox but opens in Quick Edit or remains stuck in Classic mode when accessed via Microsoft Edge.
Verify whether your organization uses SharePoint Online (Microsoft 365) or an on-premises SharePoint Server environment, as the troubleshooting steps differ significantly between the two.
Clear Microsoft Edge Browsing Data for SharePoint Online
Use this solution to verify if corrupted browser cache or cookies in Edge are forcing SharePoint to load the classic experience.
If you are using SharePoint Online, browser caching issues can sometimes prevent the modern UI from loading correctly in Microsoft Edge. Testing in InPrivate mode helps isolate whether the issue is caused by stored browser data.
Open Microsoft Edge, click the three-dot menu (...) in the upper-right corner, and select 'New InPrivate window'. Navigate to your SharePoint library and sign in to see if the New Experience loads.
If the New Experience works in InPrivate mode, return to your normal Edge window. Press Ctrl+Shift+Delete on your keyboard to open the 'Clear browsing data' menu.
Select 'Cookies and other site data' and 'Cached images and files'. Set the time range to 'All time', then click the 'Clear now' button.
Close completely out of Microsoft Edge, reopen the browser, and navigate back to your SharePoint document library to confirm the modern experience is now active.
Seek Support for SharePoint Server (On-Premises)
If you are on an on-premises SharePoint environment, the issue may stem from server-side configurations requiring administrator intervention.

Frequently Asked Questions
Why does SharePoint automatically switch to Classic mode?
SharePoint may revert to Classic mode if your browser has cached outdated site data, if specific classic features are enabled in the library settings, or if the current browser version lacks support for the modern experience framework.
How do I force a SharePoint library to use the New Experience?
As a site owner, navigate to your library, click the Settings gear icon, and select 'Library settings'. Click 'More library settings', choose 'Advanced settings', scroll down to 'List experience', and select 'New experience' to force the modern view.
Does clearing my Edge browser cache delete my SharePoint files?
No, clearing your browser cache only removes temporary internet files, cookies, and stored site data from your local computer. It does not delete or alter any documents stored securely on your SharePoint site.
What is the difference between SharePoint Online and SharePoint Server?
SharePoint Online is a cloud-based service hosted by Microsoft as part of the Microsoft 365 suite, providing automatic updates. SharePoint Server is hosted locally on your organization's own on-premises servers and is managed entirely by your internal IT team.
