Exchange 2007 mailbox size

What the crap did Microsoft do with the mailbox usage report from 2003?  Used to I could easily export a list of all users that showed their size and how many items, now I've been put on a 2007 box and have only found crappy shell commands to get odd data...depending on the script, sometimes it gives me info for 88 uers, then 93, but my exchange manager says I have 190 users.

Is there any easy way to get an accurate count of each user's size and numbers without the stupid shell...or is there a command line that might actually give me an accurate count?

Hey :)

Normally you want this:
Get-Mailbox | Get-MailboxStatistics | Select-Object DisplayName, TotalItemSize, TotalItemCount

Open in new window

We can convert values into more friendly values, and more is available than I select here. If you want it to a file:
Get-Mailbox | Get-MailboxStatistics | Select-Object DisplayName, TotalItemSize, TotalItemCount | Export-Csv "File.csv" -NoType

Open in new window

Each of the above should be run in the Exchange Management Shell. If you have any trouble executing them please don't hesitate to come back.

As for without the stupid shell... well, no, not unless someone (other than MS) writes a more extensive GUI. MS are pushing lots of the more advanced configuration options in the shell, I'm afraid it's something you would simply have to put up with.

that worked chris.

why would it pull 93 user names when I have 190 in the mailbox store?
