This is so useful I had to post it on both sites. I can’t wait to get my exchange 2003 server up and running.
Fellow MVP (and soon-to-be-published author of Essential Exchange Server 2003) Michael Smith has a cool script that will automatically send warning mail to users whose passwords are about to expire. Run it daily, and your mail-only users will never again be able to complain that their passwords expired without prior notice.
