Hi, So here's a unique problem that maybe one of you hotshots can help solve. I have a boss who gets alot of email, his current mail folder on his computer(s) is getting to be over 40 gigs, and this is after archiving. I've tried entourage (4gb limit) powermail, thunderbird, and of course mail. In fact I'm using mail right now and here's where the slow down appears. Mail tends to multi-task, ie syncing and caching and the what not. So when the big boss tries to check mail or even view a new message, it can be a minute or more just to view the new message, meanwhile apple's mail is spining it's rainbow colored wheel on caching or syncing a unrelated folder. Is there a work around for this? I'm running the latest incarnation of exchange and he's connected using imap. He has a fast connection of course and is using the latest version of Mail on Leopard with a fast machine. Any help would be appreciated, any useless criticism of course is rubbish.
