Exchange 2003 RUS to Exchange 2010 EAP

Like many of you, I’ve run into the fun situation of moving the Exchange 2003 Recipient Update Services to Exchange 2010’s Email Address Policy.  Although the Exchange Team Blog has a great script (which I highly suggest that you use) for migration, I thought that it might be best to get a list of accounts that *might* be hit with this change.  Pretty much any time that we made a change with RUS, we got bit because of some custom email addresses.

Now at my organization and in my lab, we use First and Last Name with a period separator for the email addresses.  This might be pretty standard, but if yours if different, you may need to alter the script function slightly.  Regardless, here’s the script with some decent comment fields throughout.  Hit me up with any questions!
