Is this actually common?    /shudders...
If that causes you to shudder I won't tell you the extend of the Exchange Servers I have found on the internet to date.

The problem is more that there is no 'easy' VPN solution, and without it you have the situation of companies making Exchange accessable in a semi-unfirewalled state (semi in that some ports are firewalled however the Microsoft ports are not).
