Fix Microsoft 365 Quarantine Page Loading Blank in Edge
Question details
The Microsoft 365 Quarantine page fails to display content in Microsoft Edge, showing mostly a blank page, but functions properly in Firefox.
- Product
- Microsoft 365, Microsoft Edge
- Device & OS
- not provided
- Scenario
- An administrator is trying to view quarantined emails and headings in the Microsoft Defender portal using Microsoft Edge.
- Observed behavior
- The Quarantine page appears completely blank except for the 'Review > Quarantine' navigation text, failing to load the necessary headings or messages.
Before making changes to your browser settings, verify that your administrator account possesses the correct permissions to view quarantine messages in the Microsoft 365 Defender portal.
Clear Browser Cache, Cookies, and Disable Extensions
Clearing corrupted temporary data and disabling potentially conflicting third-party extensions is the most effective way to resolve page rendering issues in Edge.
Browser cache issues or ad-blocking extensions can frequently interfere with complex web portals like the Microsoft 365 Defender admin center, preventing page elements from fully loading.
Open Microsoft Edge, click the three-dot menu in the top-right corner, and go to 'Settings'. Navigate to 'Privacy, search, and services', scroll down to 'Clear browsing data', click 'Choose what to clear', select 'Cookies and other site data' and 'Cached images and files', then click 'Clear now'.
Click the puzzle piece 'Extensions' icon in the Edge toolbar and select 'Manage extensions'. Toggle off all active extensions, refresh the Microsoft 365 Quarantine page, and see if the content loads.
Enable Internet Explorer Mode for the Admin Portal
If Edge's modern rendering engine struggles with specific enterprise portals, loading the site in Internet Explorer mode can serve as a temporary workaround.
Update or Reset Microsoft Edge
Running an outdated version of Edge or having misconfigured browser preferences can cause compatibility issues with Microsoft 365 services.
Experience Hassle-Free Document Management with WPS Office
While troubleshooting complex browser and admin center compatibility issues, ensure your local document workflow remains seamless. WPS Office is a fast, lightweight, and completely free alternative to Microsoft Office that meets all your daily productivity needs.

Frequently Asked Questions
Why does the Microsoft 365 Quarantine page load fine in Firefox but not in Microsoft Edge?
This discrepancy is typically caused by corrupted cached data, incompatible browser extensions, or specific tracking prevention settings that are active in Microsoft Edge but not in Firefox.
Will resetting Microsoft Edge delete my saved passwords?
No. Resetting Microsoft Edge to its default values clears temporary data, disables extensions, and resets startup pages, but it preserves your saved passwords, favorites, and browsing history.
What should I do if clearing cache and IE mode do not fix the issue?
If the issue persists exclusively in Edge while Firefox functions properly, you should contact Microsoft Support via the Microsoft 365 admin center, providing them with your browser version and tenant details.
How can I check if site permissions are blocking the Quarantine page?
In Edge, click the padlock icon next to the URL in the address bar when on the Quarantine page, select 'Permissions for this site', and ensure that necessary scripts and pop-ups are allowed.
