Is it possible to run a command to produce a list of mailboxes a user has full access to?

I found something to try running in PS AD module however the output was useless.

Get-ADUser mspencer -Properties * | Select msExchDelegateListBL | Export-Clixml 'c:\users\adm-dosmith\desktop\test23.csv'

Does anyone have anything?

Get-Mailbox | Get-MailboxPermission -User mspencer

This goes through every mailbox and returns any permissions the user mspencer has.

You'll need to use the Exchange Management Shell to run it as it uses the Exchange cmdlets.
