Use the Settings > Hybrid Configuration > Unfiltered Destinations page to review, add, or edit information about target sites to which you want to grant clients unrestricted access. Clients can access these sites directly, without sending the request to either the hybrid service or an on-premises explicit proxy in a filtered location, if used. Typical unfiltered destinations include organizational webmail sites, internal IP addresses, and Microsoft update sites.
Destinations listed here are added to the Proxy Auto-Configuration (PAC) file that defines how users' browsers connect to the hybrid service (see Configure user access to the hybrid service). By default, the PAC file excludes all non-routable and multicast IP address ranges from policy enforcement. Therefore, if you are using private IP address ranges defined in RFC 1918 or RFC 3330, you need not enter them here.
