Joe Tinney answered this pretty well, I'll just add that starting with Outlook 2003, by default, the OST (Offline Store) is used to keep a cached copy of the server mailbox even when nominally online. Outlook uses that cache for most operations, and only sync's it to the server every few minutes or so. > But each client with a spare partition for a Mail > client's database file... that sounds ridiculous. It is severely annoying, to be sure. We only do it for those with the giant mondo mailboxes, basically anything over 2 GB in size. What we really need is an archiving solution, but haven't been able to get money for one yet. Exchange 2010 is supposed to have a basic solution in that area, and I'm hoping that will be good for us. Again, we're talking a single file, several GB in size, that gets highly fragmented. I don't really put too much blame on Outlook here. While I suspect Outlook could probably be more efficient, there's only so much you can do under those conditions. Clients that never leave the LAN have cached mode disabled. They always talk to the server then. Exchange performs very well, even with a 70 GB plus server database in a single file that's probably more fragmented than I want to think about. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
