1) Are there more than 1 ways to assign permissions to an exchange 2010 mailbox? I know it can be done via AD permissions, but I seem to recall the mailbox user themselves can delegate permissions in Outlook.
2) are there techniques (shell commands?) to show via all possible techniques (i.e AD, Outlook) which users have which permissions over a specific mailbox?
3) is there a command that can be run perhaps via exchange management shell to show if mailbox auditing is enabled on a specific mailbox?
