If you use an Internet proxy server that requires authentication, you may encounter problems when you use apps that connect to the Internet.
Proxy servers that require authentication either require a username and password to access the Internet or authenticate users by using their current domain credentials.
Depending on your proxy configuration, you may encounter one of the following problems when you use Windows Store apps:
Microsoft is aware of these issues, and we are investigating possible solutions. More information will be provided here when it is available.
You can reduce the effect of these issues by enabling unauthenticated access through your proxy server, preferably only for connections to URL addresses that are used by each app that is having a problem. Some proxy servers may suggest that you create an allow list (what they may call a "whitelist") of URL addresses.
To resolve these issues as they relate to using Windows Store apps or to using Microsoft apps that are included with Windows 8 or Windows Update, you can include the following addresses in an allow list on your proxy server and enable HTTP and HTTPS access to them:
To resolve these issues with other apps, you may have to contact the application vendor for information about which URL addresses to include in your allow list.
