en Passant not letting life just pass on by

We are working on a security review of our Exchange environment. Part of that is to review who has permissions to access what mailboxes.

That's why I put together this little script. Using the Exchange 2007 Management shell, it reads our Exchange 2003 and 2007 environments, processing all the mailboxes. It outputs a single CSV file containing each instance where someone else (not SELF and not a SID) has permissions to a mailbox.

The heart of the script is this line of code. It is the one-liner that reads the mailbox information and filters on the rights I wanted. Without the -and and -notlike operators, I would need to filter through all of the various account permissions.

Note: It will prompt for the OU of the folder you want. If you don't specify anything and simply hit ENTER, it will use the root of your currently logged on domain.
