cyrus as a mail storage for exchange?

[malte.mueller at ewetel.net]

Hi,
i have the sad task to setup MS Exchange. Up to now Exchange was used  
in a separated network for several things but not e-mail. In my  
environment i will not give everyone access to exchange nor do i want  
to deal with two different mailstores. So, pardon this dumb question,  
but is it possible to use Exchange/Outlook and have all mails stored  
cyrus? Other things beside mail can be stored in Exchange's database.

Thanks in advance for any hint
Malte
