  • Blog Post: Upcoming Group Chat client/server support matrix

    As customers were beginning to upgrade OCS 2007 R2 deployments with Lync, the question of support for Group Chat showed that what was originally thought to be a simple answer required a more complex matrix to illustrate.

  • Blog Post: Lync 2013 Persistent Chat - Group Chat done right

    I have worked with Group Chat for some time and it was always a love/hate affair. What the product offered was well understood and when used right helped reduce the need for email.
