The 403 error shown is a “forbidden/access denied” response from the website’s content delivery network (CloudFront), not from Windows or Microsoft Edge itself. It means the site or app is blocking the request or is misconfigured.

For Microsoft Edge on Windows 11, the only client-side actions that can be tried are:

1. Open the site in an InPrivate window in Edge and try again.
2. If it works in InPrivate, clear the normal browsing cache and cookies for that site, then retry.
3. If the error persists even in InPrivate, the issue is on the website/app side (CloudFront configuration, firewall, or permissions). In that case, contact the site or app owner and provide the full error text and Request ID so they can fix their CloudFront configuration.

If the error occurs when accessing Microsoft 365 resources (SharePoint/OneDrive), also try:

1. Sign in to Microsoft 365 in an InPrivate window in Edge.
2. If access works there, clear the Edge cache and cookies.
3. If it still fails, contact the SharePoint/OneDrive administrator to verify permissions and service health.
