Along these same lines, the open source edition of Zimbra (http://www.zimbra.com/ - runs on CentOS/RHEL/Ubuntu) is fairly easy to setup from install script and has support for LDAP authentication. The trick would be to MX to it and then, as Tim suggests, since Zimbra uses Postfix, you could rig in some sort of dual delivery with the transport and/or virtual tables (I would think). Zimbra has a robust web client that is ajax-based and very outlook like, so, would be a suitable sub for the duration. You can even upload a PST export of an Outlook's Contacts, Calendar, and Tasks into the Zimbra server (well, email folders too for that matter), so, in theory, each users Outlook environment would be more or less statically cloned into Zimbra (as of the PST snapshot). VMWare owns Zimbra now and has been ramping up its development and seems to remain committed to the open source edition.
