How to Fix Custom Microsoft Sign-In Page Changes Not Showing in Edge

Product: Microsoft Edge / Microsoft Account
Device & OS: not provided
Scenario: An administrator or user is verifying organization branding updates on a custom Microsoft sign-in page.
Observed behavior: The newly configured logo and background colors fail to appear when accessing the sign-in page through the Microsoft Edge browser.

Before you start

Ensure you have the required Global Administrator or Company Administrator privileges in Microsoft Entra ID (formerly Azure AD) and have waited at least 15 minutes for your recent branding changes to propagate globally.

Solution 1Recommended

Clear Edge Cache and Test in InPrivate Mode

Clearing the browser cache resolves issues where Microsoft Edge loads an outdated, cached version of your sign-in page instead of the new branding.

Browsers frequently cache static assets like logos and CSS backgrounds to speed up page loading. When a company administrator updates the sign-in page branding, local caches can prevent the new changes from displaying immediately.

Open Edge Settings

Launch Microsoft Edge and click the three-dot menu (Settings and more) in the top-right corner, then select 'Settings'.

Clear Browsing Data

Navigate to 'Privacy, search, and services' on the left sidebar. Under 'Clear browsing data', click the 'Choose what to clear' button.

Select Cache and Cookies

Check the boxes for 'Cookies and other site data' and 'Cached images and files', then click 'Clear now'.

Test with InPrivate Mode

Press Ctrl+Shift+N to open a new InPrivate window. Navigate to your custom Microsoft sign-in page URL to verify if the new background colors and logos now appear.

Clear Edge Cache and Test in InPrivate Mode

Testing Alternatives: If InPrivate mode works, your issue was definitely local cache. You can also verify the page changes on a completely different device or via another browser to confirm the deployment was successful.

Solution 2

Verify Branding Requirements and Admin Permissions

Ensure that the uploaded image assets meet Microsoft's strict file size and dimension limits, which are required for custom sign-in pages to update successfully.

Frequently Asked Questions

How long does it take for Microsoft custom sign-in page changes to appear?

Changes typically take effect within 15 minutes to an hour. However, local browser caching or global propagation delays can make it appear as though the changes failed. Always test using an incognito or InPrivate browser window.

What are the exact image size limits for the Microsoft sign-in page banner logo?

The banner logo must be exactly 280 x 60 pixels, strictly under 10 KB in file size, and saved in a transparent PNG or JPG format. Uploading an improperly sized image will prevent the branding changes from applying.

Why can't I see the 'Company branding' option in Microsoft Entra ID?

Customizing the sign-in page requires specific licensing (Microsoft Entra ID P1 or P2, or an eligible Office 365 subscription). You must also be signed in with a Global Administrator or appropriate admin role to view and edit these settings.

Will these branding changes affect all users in my organization?

Yes, once the company branding is successfully configured and propagated, it will apply universally to all users authenticating against your tenant's custom sign-in URL.
