Yes, but you need target them with "Thin Client" Agent, and ofcaurse if you know their IP Range.
Hi Dmitriy, you mean we need to install the "old" thin client agent instead of the agentless approach in Mobility Manager? In that case, we will not be able to manage iPhone, Blackberry etc? I though the thin agent is on WinCE and WM only?
I'm not sure he is understanding the original question. You CANNOT manage a mobile device if they only connect to Exchange via browser. "Agentless" management of devices is only possible via the devices Active Sync client.
