Then tell them their only option is to buy Exchange Server and Outlook 
for everyone - but explain that this 'feature' *still* will not work for 
recipients that are outside of your control (ie, it will only work for 
local recipients - and I *think* it is possible to set up Trusts with 
other external Exchange Servers, but not sure, and if it does, it 
requires the explicit cooperation of the other systems admin).

Bottom line: do NOT promise the impossible to a client just to win the 
business. It is a losing proposition, as you are beginning to see...
