My No. 2 pick is the improved storage reliability. This lumps together several discrete enhancements, but the short story is that you can now run Exchange reliably without dealing with Windows clustering, RAID arrays, or fancy Enterprise-class disks. It'll be cheaper to store mailbox databases and faster to recover mailboxes in the event of failures.

My No. 3 pick is MailTips. Are you about to accidentally send a personal e-mail to the whole company? A a time-sensitive e-mail to someone who is on maternity leave for six months? A 30MB attachment to people who have 20MB attachment size limits on their mailboxes? MailTips tells you before you send the message.

[ See Microsoft Exchange Server 2010 highlights. ]

And my No. 4 pick is conversation view. Have the arrangements for a company party Friday night cluttered up your mailbox to the point where you can't find the approval e-mail for the urgent customer visit that you need to book today? Switch to conversation view, and collapse those 50 party discussions into one expandable node. This isn't a new idea; we were doing threaded conversations on bulletin board systems 25 years ago. But it is new to Outlook and OWA, and it's more than welcome.
