What is the limit to individual mailboxes, or is there one, I have set the database to max at 75 gig (currenty priv.edb at 29gig). I have one user using 14gig (36,000 email plus), next smallest is 5gig. 12 users in all (lawyers mostly) Exchange perfomance is really getting bad. Is the user using 14gig causing perfomance issue? Dell PE server with 4gig mem, P4 3.0 dual , gigabit network, plenty of raid disk space, 120 gig plus availabe. Should I defrag? Should I set limits, if so to what size? I have been trying to get them to archive. Any suggestions?
