Important
When specifying the domain name, you can use an asterisk (*) to
specify a set of computers. For example, to specify all computers
in the microsoft.com domain, type the domain name as
*.microsoft.com. Note that the asterisk can appear only at the
start of the domain name, and can be specified only once in the
name.
When you specify a domain name, specify the computer name using
the fully qualified domain name (FQDN). For example, type
computer_name.microsoft.com, and not //computer_name.
If the DNS is not configured correctly, rules using URL sets
may not be applied as expected.
After you click Apply in the details pane, the policy is
updated. The new policy applies only to new connections.
