Exchange 2010 DB is growing rapidly. Is there a tool to determine what mailbox is causing this growth?

We have 2200 mailboxes on this database and it has continue to increase in size versus the other databases. How do I pinpoint to which mailbox this is coming from?

"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.

you can find out using powershell command

Select top 100 mailboxes by totalitemsize and export to CSV file

[PS] C:\>Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Sort-Object TotalItemSize -Descending | Select-Object DisplayName,TotalItemSize -First 100 | Export-CSV top100mailboxes.csv

Will this show incoming and sent emails? We had an issue before where a user's PC was infected and was sending out continuous spams. I remember contacting MS and they had a tool that shows real time high utilization of the mailbox.
