This topic discusses the ability of Microsoft Lync Server 2010 communications software clients to coexist and interact with clients from earlier versions of Office Communications Server.
There are two types of client compatibility:
- Multiple points of presence (MPOP) The ability of a single user to sign in to a server with multiple clients and multiple client versions.
- Interoperability The ability to interact with another user who is signed in using a different client type, or an earlier version of the same client.
Planning for Compatibility
Lync Server 2010 fully supports interoperability among Lync Server 2010 clients.
Most instant messaging (IM), presence, and voice features are also supported when interacting with Microsoft Office Communications Server 2007 R2 and Microsoft Office Communications Server 2007 clients. For details, see the "Lync Server 2010 Interoperability with Previous Client Versions" section later in this topic.
