I have an Exchange Server 5.5 Sp3,70 users, 768mb RAM, RAID 5 76gig. It has been stable for the past 3 months. Just the other day all my Outlook clients could not send mail and hung on opening their mailboxes. No immediate error msg or event erroron the clients or server. All Oulook 2000 clients hung indefinetely. After a failed attempt to restart my Exchange Serices I rebooted the server. After reboot all is well again.
Anyone else experience this that can offer advise?
