Free (or cheap) IM Program for Business
I am looking for an IM program that would be appropriate for a business environment. What I would like is to be able to manage the server, and have all of the communications stay within the local domain, no outside access.
Let me know if you are aware of a program that would work well for this. If anyone has had any experience with Office Communicator or Groove I'd be interested in learning a bit more about how those worked out for you as well.
