Does anyone know of a way to retrieve the ACLs set on 2007 mailbox folders
using Powershell?

Say for example, user Joe has granted reviewer rights on his Inbox to Carla
- I'd like to use Powershell to find and display that information.

I've tried using the get-mailboxpermission and get-adpermission cmdlets but
haven't found a way of retrieving them.

Any help gratefully received...
All the best,
Darren
