Does anyone know if there is a way to see the mailbox size from the EMC? In 2003 I think I changed the columns to show the mailbox size, but when I go in to add columns in 2007 mailbox size is not listed. We use to go in once a month and see who was coming close to the storage limits and send them an email reminding them to clean up to free space.

Not from the UI, you will have to open an Exchange Powershell window and run the Get-MailboxStatistics command. Get-MailboxStatistics -Server <ServerName> This you can pipe into a file, sort or filter. Get-MailboxStatistics |where {$_.TotalItemSize -gt 100MB} | sort $_.TotalItemSize |FT DisplayName,ItemCount,TotalItemSize see more examples at http://technet.microsoft.com/en-us/library/bb124612.aspx Shane

Here's my contribution. I wrote this script to include some additional user information in the Mailbox Size report.Get-User -ResultSize Unlimited | Where {$_.RecipientType -eq "UserMailbox"} | Select DisplayName, Company, City | foreach { $MailboxInfo = Get-Mailbox -identity $_.displayName$MailboxStat = Get-MailboxStatistics -identity $_.displayName Add-Member -InputObject $_ noteProperty UseDefault $MailboxInfo.UseDatabaseQuotaDefaultsAdd-Member -InputObject $_ noteProperty WarningQuota $MailboxInfo.IssueWarningQuotaAdd-Member -InputObject $_ noteProperty SendQuota $MailboxInfo.ProhibitSendQuotaAdd-Member -InputObject $_ noteProperty SendRecieveQutoa $MailboxInfo.ProhibitSendReceiveQuotaAdd-Member -InputObject $_ noteProperty QuotaStatus $MailboxStat.StorageLimitStatus Add-Member -InputObject $_ noteProperty TotalItems $MailboxStat.ItemCountAdd-Member -InputObject $_ noteProperty TotalSizeMB $MailboxStat.TotalItemSize.Value.ToMB()Add-Member -InputObject $_ noteProperty DeleteItems $MailboxStat.DeletedItemCountAdd-Member -InputObject $_ noteProperty DeletedSizeMB $MailboxStat.TotalDeletedItemSize.Value.ToMB() -PassThru } | Export-Csv -Path D:\MailboxSize.csv
