I love PowerShell, in Exchange you called it Exchange Management Shell (EMS), this year I working a lot of request which solvable with EMS that’s why I more in love with it! Red heart

So one of the request is how to find users which is not using default Quota that already assign to Database ? Individually you can check from EMC then go to Mailbox Features tab and you can check Storage Quota whether it have checkmark or not.

Or you can open EMS then execute the following command below :

Get-Mailbox –id krisnais | select DisplayName, *usedatabasequota*


Mine have FALSE flag meaning I’m not using default quota which already assign to Database, if you want to know the entire users, you can give a condition like this :

get-mailbox | where {$_.UseDatabaseQuotaDefaults -eq $False}
