Introduction

If you’re setting up or supporting Lync Server 2010, a good practice is to develop your understanding of how IM works in a Lync Server deployment. This means learning about:

  • What IM communication and collaboration looks like for Lync 2010 users
  • How Lync 2010 signs in, subscribes to users’ Contacts lists, receives server configurations and policy settings, and starts and elaborates on IM sessions by adding people, program sharing, or both

An understanding in these areas can support you when planning for client sign-on methods (manual or automatic configuration) and when troubleshooting.

Summary

This chapter describes how Lync Server supports a Lync 2010 IM session and includes detailed descriptions about the SIP traffic that results from users starting an IM conversation (between two users) and escalating the conversation into an IM conference (with more than two users). Adding in program sharing is also covered.
