If you use Group Policy to redirect one of the Windows 7 Libraries to a network location, your clients may get a message “some features are unavailable due to unsupported libraries locations. Click here to find more…” Message appears when you open any folder in the affected library.

This would happen if following is true:

• A Library redirected to a network location
• Offline Files are not enabled for this Library on the client side.
• Windows Search is not running on the server side

If you can’t fix above issues you can get rid of this message by disabling Library features which depends file indexing. This is done via group policy:

User Configuration > Policies > Administrative Templates > Windows Components > Windows Explorer > Turn off Windows Libraries features that rely on indexed file data
Set this policy to Enabled.
