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.

OCS 2007 R2 Group Chat–SIOPS?
Has the term SIOPs (Standard Input Output Panels) been mentioned in regards to Group Chat and you wondered what they were only to find that an Internet search turns up links saying it isn’t supported?

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. The downside was the solution was difficult to install and manage (this is being polite <grin>). The release of Lync...

Group Chat File upload issue
In testing Group Chat with an XP workstation for a customer, I found I could not upload a file successfully. The truth is that I haven’t been able to do this for a while but ignored it.
