Step-By-Step: Installation of Skype for Business Server 2015 Enterprise Persistent Chat


The role of Persistent Chat Server allows users to participate in multi-stakeholder thematic conversations persistent over time.

Teams can efficiently share information, ideas and decisions with each other. Discussions are persistent, allowing users in different geographical areas to participate even when they are not simultaneously online.

This role allows you to search content, to create notifications and filters to follow conversations on specific topics.

Since Lync Server 2013, the feature is available directly in the Lync client.

Persistent Chat server is an optional role in Skype for Business 2015. Servers are managed in a dedicated farm and depends on the front end to the routing of the messages.

This role is primarily composed of conversation and compliance services. The Conversation is responsible for persistent chat server database service. The compliance service enables archiving of the content of conversations and events.

Web services, dependent on IIS, they are handled by the front-end server. Web services are used for the publication and recovery files as well as the management of the conference rooms.

Persistent Chat Server uses two databases:

  • The database 'mgc' for the hosting of data such as history and the content of conversations, configuration and provisioning of user data
  • The database "mgccomp" for compliance data archiving

These databases can be located in the same SQL Server instance or different SQL Server servers.

Persistent cat is the only role Skype for Business server whose farm can be stretched between two sites.

Various architectures options available:

  • Environment Standard edition including the role of persistent chat collocated with the front end server
  • Environment Standard edition including the role of persistent chat deployed on a dedicated server
  • Environment in Enterprise edition including the role of persistent chat deployed on a dedicated server
  • Environment in Enterprise edition including the role of persistent chat deployed on several separate servers

The following table summarized the capabilities supported by the role:
