Script Download: 

This script creates mailbox usage report in Microsoft Exchange 2010. It will use IssueWarningQuota and TotalItemSize to calculate the usage rate.

In a real world, IT Administrators may want to know the usage rate of specific mailboxes. They can use Exchange Management Shell to get total item size and issue warning quota for mailboxes very easily. But issue warning quota could be set for all of the mailboxes in a database or on a per-mailbox basis. IT administrators need a script to help them to decide which quota is applied. Then, they want to use correct issue warning quota to calculate the mailbox usage.
