One point not being made here is that nearly every wireless carrier requires you to add an Enterprise Data Plan to your service in order to use an Exchange connector. AT&T requires this with the iPhone. Verizon, T-Mobile, etc. all require it for the Blackberry. I haven't heard of a single device/provider that doesn't require an elevated service level to allow for enterprise mail access. So there's a security by obscurity to start with: the average user doesn't know to ask for the Enterprise plan, let alone what Enterprise even means in context. So the scenario here requires that a) the salesman talked them into it, b) they bought into that service for the extra $15 on top of the data plan, or c) they consulted with the company's IT department or policies and knew they had to get that service. If they didn't, they simply cannot connect to the Exchange account. There's very little "oops, I didn't know what I was doing" here. I hope that most companies have a clear policy against checking your work e-mail from personal devices, and on your own time. There are legal implications for overtime pay. We may look the other way in startups, but this can't always be done. Most law firms require this, unilaterally. It's part of the deal-- we'll pay your enterprise data plan in exchange for knowing that we may wipe the device, control which apps you can install [this is another can of worms], so on and so forth, per the requirements of malpractice insurance and data security. In a perfect world this wouldn't be required, but I think we all know this can't possibly be the case in many industries.
