Enable or disable remote user access in Skype for Business Server
Remote users are users in your organization who have a persistent Active Directory identity within the organization. Remote users often sign in to Skype for Business Server from outside your network by using a virtual private network (VPN) when they are not connected to your organization’s network. Remote users include employees working at home or on the road and other remote workers, such as trusted vendors, who have been granted enterprise credentials. If you enable remote user access for remote users, supported remote users connect over the Internet and do not have to connect using a VPN in order to collaborate with internal users using Skype for Business Server.
To support remote user access, you must enable remote user access. When you enable remote user access, you enable it for your entire organization. If you later want to temporarily or permanently prevent remote user access, you can disable it for your organization. Use the procedure in this section to enable or disable remote user access for your organization.
Enabling remote user access only specifies that your servers running the Access Edge service support communications with remote users, but remote users cannot participate in instant messaging (IM) or conferences in your organization until you also configure at least one policy to manage the use of remote user access. Skype for Business Server policy settings that are applied at one policy level can override settings that are applied at another policy level. Skype for Business Server policy precedence is: User policy (most influence) overrides a Site policy, and then a Site policy overrides a Global policy (least influence). This means that the closer the policy setting is to the object that the policy is affecting, the more influence it has on the object. For details about configuring policies for the use of remote user access, see Configure policies to control remote user access in Skype for Business Server.
To enable or disable remote user access for your organization
From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or is assigned to the CsAdministrator role, log on to any computer in your internal deployment.

To enable remote users to sign in to your servers running Skype for Business Server, you must also configure at least one external access policy to support remote user access. For details, see Configure policies to control remote user access in Skype for Business Server.
