[ale] linux email solution that supports exchange calendar access

[Geoffrey]

I guess I need to clarify the problem.  Tenn location has an exchange 
server all their users access email, do calendaring via outlook to this 
exchange server.

What we want to do is implement a Linux mail server at the client site 
that supports calendaring whereby a Linux based client can view calendar 
data (free/busy) for users hosted on the exchange server.

Emails destined for the client site would be forwarded to the Linux mail 
server at the client site.

The problem is the politics involved dictate that the solution can not 
require all the Outlook users to change the configuration of their 
Outlook client in order to make this work.

I know I'm likely looking for the 'holy grail' here, but those are the 
issues we are dealing with.
