What's wrong when viewing Exchange 2007 quota settings for all users?

Recently I was asked by management to provide them with the list of users who do not have default mailbox quotas restrictions on an Exchange 2007 CCR server. I told myself, well that's pretty straight forward. I can use Get-Mailbox cmdlet in Exchange Management Shell (EMS) and send the output to a text file, nicely format it in excel and I am done. So, I went ahead and ran the following command with the output show below.

>Get-Mailbox -ResultSize "Unlimited" | more

I noticed in the output that last column (ProhibitSendQuota) contained a lot of "unlimited" values. That meant that I had 99% percent users that had unlimited quotas on their mailbox for sending email. But that could not be. Because during the CCR setup, every database had quotas defined and all mailboxes (new and migrated) by default were set to use database defaults. Yes, there were some exceptions but these mailboxes were given unlimited on a purpose. Anyways, I wanted to confirm this so I looked at two mailboxes above in Exchange Management Console (EMC) and noticed that both are set to use database default quota settings as expected.

So, why does the command Get-Mailbox show these values incorrectly (marked in Red). Well that's a question to be answered by Microsoft Exchange Team. To me, this is a minor bug in the Exchange 2007 that should be fixed.

When using Get-Mailbox to get mailbox settings I would expect to see correct values as defined at the mailbox database level and shown below.

So, to answer my original question and provide management with the mailbox quota report, I run the following cmdlet.Get-Mailbox --ResultSize Unlimited | Where {$_.UseDatabaseQuotaDefaults -eq $false} | Select Name, IssueWarningQuota, ProhibitSendQuota, ProhibitSendReceiveQuota, ExchangeVersion | FT

This will give you list of all users who are not using the default database settings for mailbox quotas on Exchange 2007.
