HEY MOD -- leave my posts alone.... This isn't a "tech issue", don't bury this in that waste of space tech issues thread. Creating one single thread to handle all the issues is counter productive and hurts this forum.
I originally posted that Corporate Directory is gone (before it was moved), but this is only partially true. It is actually merged into the main Contacts program.
Simply go into Contacts and start searching, you'll then see your "Account Name" show up at the bottom, click that and it will show you the user with their email. Click that then you can see their full details!
I think this is actually an improvement!
