Is it possible to limit the creation of new mailboxes to a particular storage group or mailbox store?Thank YOU

Hi, Actually there isn't any way to limit the number of mailbox creation on the database/storage group. You may need to count itregularly and need to take decision. If you are using Exchange 2007 then you can use below command to get the number of mailboxes for all mailbox databases of your Exchange environment.Get-MailboxDatabase | Select Identity, @{Name="Number Of Mailboxes";expression={(Get-Mailbox -Database $_.Identity | Measure-Object).Count}}You canalso create a powershell script to export the result and get it on email. You can even schedule it to run on regular basis to monitor it. You can check below article for scheduling script.How to Schedule PowerShell Script for an Exchange Taskhttp://exchangeshare.wordpress.com/2008/12/08/how-to-schedule-powershell-script-for-an-exchange-task/Amit Tank || MVP - Exchange || MCITP - Exchange 2007 || http://ExchangeShare.WordPress.com
