It was quite difficult in Exchange 2007 to determine the size of a mailbox database using PowerShell. At that time, the Get-MailboxDatabase cmdlet did not return the size of the database, and instead, you had to use the cmdlet to determine the path to the EDB file and calculate the file size using the Get-Item cmdlet or WMI. With Exchange 2010, this was changed and determining the size information turned out to be very simple, and the information can easily be retrieved using the Get-MailboxDatabase cmdlet. In this recipe, we will take a look at how to report on the mailbox database size using the Exchange Management Shell for Exchange 2013.
