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.

If you've read my site for any time, you know that I am a big-time scripter. I look for scripted solutions to most common problems that I have to deal with first. Touch 1,200 accounts by hand? Write a script? Hmmm.. If I cannot find a viable (scripted) solution within 15 minutes of googling, then I might ping a friend or co-worker and see if they've done something similar, but likely go for the manual method.
