We just started testing GW Messenger here and sent it out to a few users so far to test. Is there a way to limit who users can gain access to if we did a full push out of GWM? What I'm hoping is a way to limit users so that they can only contact other users from a Group or OU that they are a part of. Our primary concern is we want to prevent a bunch of tech support requests for ourselves with users trying to bypass our tech support system and contacting us directly.
