I've been introduced to the wonders of persistent group chat, and love the idea.
We're on O365, and I was disappointed to learn that Lync Online does NOT feature chat rooms! Also, no expectation of it being released online any time soon. The on-prem Lync Server does have it, however.
Given that we're O365 customers, are we able to also run Lync on-prem? Is the complexity worth it just for the groups? Would there be additional cost? Should I instead do complexity another way, and roll out hipchat alongside Lync, as SAM has done?
If MS would at least say it's coming out in the next version, then I'd try waiting, but this feature seems really nice. I can't believe I didn't hear of it till now.
