Symptoms
Consider the following scenario:
-
You enable Enhanced Protected Mode (EPM) in Windows Internet Explorer 11.
-
You go to a website, and the identity provider (idP) of the website is in a different sandbox than the website. For example, login.live.com is in a different sandbox than bing.com.
-
The website requires that EPM is enabled in Internet Explorer 11.
In this scenario, you may encounter cookie-related issues. For example, you cannot sign in to the website, or your personal information is not loaded correctly after you sign in.
Cause
This issue occurs because cookies are not shared when the idP and the website are in different sandboxes.
