# Lync Connector

The Lync Connector captures instant messages from a Skype for Business server, Lync server, Lync Group Chat server, or Office Communications Server (OCS). The connector captures messages by extracting data directly from the server’s archiving database.

When you run the connector’s `synchronize` action, the connector retrieves messages for a given time slot (specified by the `IntervalSeconds` configuration parameter). The connector only retrieves messages from conversations that are complete. A conversation is considered complete when there is no activity for a configurable period of time (specified by the `ChatExpirySeconds` configuration parameter).

After retrieving conversations from the repository, the connector can transform them into documents using an XSL stylesheet. The connector then sends the documents to CFS, which indexes them into an IDOL server.

After the documents are indexed, IDOL server automatically processes them, performing a number of intelligent operations in real time, such as:
