Yeah, I didn’t get into that in depth so I don’t have *all the details or rationale; I’m using it as the sort of thing you see down here in the trenches with smaller organizations than what you’re used to dealing with.
You see “corner cases” like that *all* the time in the field.
FYI, the break point for “we need to have a full time domain/Exchange admin on staff” seems to be around 40-50 users. At that point, just calling in consultants on occasion won’t do it as you’re looking at almost daily issues (between the server and the users).
Clarification: That’s the break point *if* they’re using domains/Exchange.
Lots of them try to avoid that expense as long as possible.
I’ve seen Exchange work well in and organization, and I’ve seen it be an absolute mess. It’s perfectly capable software in the right hands, and a disaster looking for someone to happen to in the wrong hands. IMPNSHO.
