Create a topic feed
-
In the Chat rooms view of the Lync main window, click the Add button.

You may want to create topic feeds for people whose communications are important to you (for example, create one that uses your boss’s name as a keyword) or for topics you’re working on. Or, decide on a word or acronym that you’ll use in messages that you want your colleagues to see, and ask them to set up a topic feed for that term.
