Configure policies to control federated user access in Skype for Business Server

When you configure policies to support communications with federated partners, the policies apply to users of federated domains. You can configure one or more external user access policies to control whether users of federated domains can collaborate with your Skype for Business Server users. To control federated user access, you can configure policies at the global, site, and user level. 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.

Note

You can configure policies to control federated user access, even if you have not enabled federation for your organization. However, the policies that you configure are in effect only when you have federation enabled for your organization. For details about enabling federation, see Enable or disable remote user access. Additionally, if you specify a user policy to control federated user access, the policy applies only to users that are enabled for Skype for Business Server and configured to use the policy.

To configure a policy to support access by users of federated domains

  1. 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.

  2. Open a browser window, and then enter the Admin URL to open the Skype for Business Server Control Panel.

  3. In the left navigation bar, click External User Access, and then click External Access Policy.

  4. On the External Access Policy page, do one of the following:

    • To configure the global policy to support federated user access, click the global policy, click Edit, and then click Show details.

    • To create a new site policy, click New, and then click Site policy. In Select a Site, click the appropriate site from the list and then click OK.

    • To create a new user policy, click New, and then click User policy. In New External Access Policy, create a unique name in the Name field that indicates what the user policy covers (for example, EnableFederatedUsers for a user policy that enables communications for federated domain users).

    • To change an existing policy, click the appropriate policy listed in the table, click Edit, and then click Show details.

  5. (Optional) If you want to add or edit a description, specify the information for the policy in Description.

  6. Do one of the following:

    • To enable federated user access for the policy, select the Enable communications with federated users check box.

    • To disable federated user access for the policy, clear the Enable communications with federated users check box.

  7. Click Commit.

To enable federated user access, you must also enable support for federation in your organization. For details, see Enable or disable federation and public IM connectivity.

If this is a user policy, you must also apply the policy to users that you want to be able to collaborate with federated users. For details, see Assign an external user access policy.
