Managing instant messaging
The BlackBerry Collaboration Service is designed to provide a connection between your organization's instant messaging
server and the collaboration client on BlackBerry devices. In some instant messaging environments, you can use TLS or
HTTPS to encrypt the connection between specific instant messaging components.
The BlackBerry Collaboration Service supports up to 2000 connections for instant messaging sessions on the following
instant messaging servers:
• Microsoft Office Live Communications Server 2005
• Microsoft Office Communications Server 2007
• Microsoft Office Communications Server 2007 R2
• Microsoft Lync Server 2010
• IBM Lotus Sametime
The number of connections that the BlackBerry Collaboration Service supports for instant messaging sessions on the
Novell GroupWise instant messaging server is limited to the number of Windows sockets that are available.
