Hi folks, I wonder if anybody has a clue as to my performance problem. Remember I did a fresh install on a 'new' machine (PIII 700, 650MB, W2KSP4)? I had the users migrated by simply copying stuff to pst file and then back to the new system (new domain, new accounts) since I gave up messing exmig.exe finally :) Admittedly, my personal mailbox is quite big, we're talking about 370MB in 25K objects, but this wouldn't normally justify for a 5 sec lag would it? The server machine is running at 800MB and has a cpu load of around 8 to 10% if nothing else happens. I searched the KB but it didn't provide any useful hints. Network is fine, all done and set, no problem here... Client is XP/OfficeXP with lastest service packs applied on a 1.4GHz/512MB machine. Any help is greatly appreciated. Thanks Mark
