Configure XMPP gateway access policies and certificates

XMPP federation defines an external deployment based on the eXtensible Messaging and Presence Protocol (XMPP). An XMPP configuration allows users access to XMPP domain users by:

  • IM and Presence - person to person only

  • Creation of XMPP federated contacts in the Skype for Business client

When you configure policies for support of XMPP federated partners, the policies apply to users of XMPP federated domains, but not to users of session initiation protocol (SIP) instant messaging (IM) service providers, or SIP federated domains. You configure an XMPP federated partner for each XMPP federated domain that you want to allow your users to add contacts and communicate with. Once the policies are in place, you need to configure the XMPP Gateway certificates.

Note

XMPP functionality is deprecated in Skype for Business Server 2019, but can be continued in a legacy server in coexistence with Skype for Business Server 2019. Make sure you have already deployed the legacy server (Skype for Business Server 2015 / Lync Server 2013) XMPP Gateway, and configured the access policies to enable users for legacy XMPP Gateway. For details, see Migrating XMPP Federation.
