You can get a nice report by using a powershell script I always use, which is Get-MailboxReport from Paul Cunningham:

I would recommend this. You can format the Excel spreadsheet out so it is presentable, and then figure out who has what in each folder listed within the mailbox. I use this report all the time for Exchange sizing.

Get-Mailbox -Database DatabaseName -resultsize unlimited | % {Get-MailboxStatistics $_ | select DisplayName,ItemCount | Sort-Object ItemCount}
Do the 600 users are on same DB or located on different DB. If they are on same DB then you can use cmdlet posted by Justin but if they are on different DB the best way to use preparing the CSV file.

Say, your CSV has Username as header..


Import-Csv C:\Filename.csv | foreach { Get-MailboxStatistics $_.Username } | Format-Table Displayname,ItemCount
