Fix Classic Exchange Admin Center Keeps Opening the New Version
Product
Microsoft Exchange Online
Device & OS
not provided
Scenario
An administrator is trying to access specific settings available in the Classic Exchange Admin Center but is forced into the modern interface.
Observed behavior
Clicking the link for the Classic Exchange Admin Center automatically redirects specific administrator accounts to the new version, preventing access to the old dashboard.
Before you start

Ensure you have an active internet connection and your Microsoft 365 Global Administrator or Exchange Administrator credentials ready to test account permissions.

Solution 1

Test with Private Browsing Mode

Use an Incognito or InPrivate window to rule out browser caching issues that might be forcing the redirect to the new interface.

Sometimes, browser caches or saved cookies default your login session to the newer modern Exchange Admin Center. Testing in a clean browsing session helps determine if the issue is local to your browser.

1
Open a private browsing window

Launch your web browser and open an Incognito window (Chrome) or InPrivate window (Edge).

2
Navigate to the Exchange Admin Center

Go to the Microsoft 365 admin portal and sign in with your administrator credentials.

3
Access the classic interface

Click on 'Exchange' under the Admin centers menu, then look for the option to switch to the classic Exchange Admin Center and observe if the redirect still occurs.

Frequently Asked Questions

Why is Microsoft forcing the new Exchange Admin Center?

Microsoft is gradually deprecating the Classic Exchange Admin Center in favor of the modern version to provide enhanced security features, better performance, and a more streamlined administrative experience. Redirects are implemented to encourage adoption of the new interface.

Will the Classic Exchange Admin Center be permanently retired?

Yes, Microsoft has announced the deprecation of the Classic Exchange Admin Center. Features are continuously being migrated to the modern admin center, and eventually, classic access will be entirely removed for all tenants.

Does clearing browser cache fix the redirect issue?

If the redirect is caused by a local session token or cached preference, clearing the cache or using private browsing can temporarily restore access. However, if Microsoft has enforced the new experience on your account from the backend, clearing the cache will not bypass the redirect.

Are specific permissions required to view the classic interface?

Yes. Only users with the Exchange administrator or Global administrator role can fully access the Exchange Admin Center. If your permissions are improperly synced or missing, the system may block access or force a redirect.
