We have a few thousand users and no limits right now. Iam looking for a script that will add limits to their mailbox to issue 300MB warnings to anyone below 250MB, and 550MB warning to the 500MB users, etc. Anyone have any ideas on how to script this through AD? We are thinking about doing it in tiers and I could probably get the "below 300MB", etc usernames into a file, but not sure how to script to apply the limits we want to those users. Thanks, Dan
