"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Sort-Object TotalItemSize -Descending | Select-Object DisplayName,TotalItemSize -First 30

This will give you the top 30

How can I output to csv file
timgreen7077Exchange EngineerCommented:
you didn't copy it correctly, because it would have also gave you the size. all you have to do is copy and paste. No need to change anything.

I copied correctly and how to put output c drive
timgreen7077Exchange EngineerCommented:
you can also manually type what I sent you.
timgreen7077Exchange EngineerCommented:
if output didn't show size then something was wrong. I tested this before I sent it to you.
timgreen7077Exchange EngineerCommented:
drive doesn't matter. if you don't get this working correctly l, out to csv won't work correctly either.
timgreen7077Exchange EngineerCommented:
output to csv

Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Sort-Object TotalItemSize -Descending | Select-Object DisplayName,TotalItemSize -First 30 | Export-CSV c:\temp\top30mailboxes.csv
