We are currently in the process of stripping down mailbox permissions for our users. I used the following procedure to export the info into a ".csv" file for easy viewing.
- Log onto the domain administrator account on your Exchange server.
- Open the "Exchange Management Shell"
- Navigate to the desktop with the "cd" command.
- Type in the following command, replacing user.name and filename with the user you would like to audit.
"Get-Mailbox | Get-MailboxPermission -User USER.NAME | Export_Csv -NoTypeInformation FILENAME.csv"
