I just bought hp ml 330 g3 (xeon 2.4, 512 mb ram, 10k scsi) with sbs 2003 pre-installed. Everything is configured as it should (wizards…) and working but users complain about poor performance of exchange server. Some of them are working with Outlook 2003 and Outlook 2002. There is total of 8 users! No errors in event log. ????
