Outlook 2010 "Rooms" button not working properly

Application versions:
Exchange is 2010 SP2 (14.2.390.3)
Outlook is 2010 (14.0.7128.5000)

Experts,

Recently I set up room calendars for our small organization.  I wanted to include equipment calendars as well as room calendars when using scheduling.  I tried to change the Address List "All Rooms" and ended up deleting and recreating it.  Ultimately, I changed my equipment calendars to room calendars and got what I needed.  

However, I've caused my own issue.  Now when users are scheduling a meeting and hit the Rooms button at the end of the location field, they initially get an error.  I'm unable to recreate the error because now the default is the GAL.  

So my question is, how can I re-enable the Rooms button to show rooms in the address book, rather than the GAL?
Bonus question, Can I customize the view of the Rooms view in the address book to show location, equipment and capacity?
I've configured the custom equipment fields but I see the standard headers in the Address book.
