Configuring squid proxy

Configure Squid to allow a pass throu for the exchange server.

Maybe I don't understand exactly what you are tyring to accomplish in doing that, but here goes...I wouldn't configure a hole to your exchange server directly, but what you could do...is configure a proxy pass thru to your Exchange Servers Outlook Web Access service if you are running IIS. That way...you are only allowing access to Port 80 services. Oh...and all Admins in Adminland will agree that you should use the microsoft baseline security analyzer on the server, and run Windows Update frequently if you are going to do that.
