During the setup of the mailbox role, the Exchange 2013 installation wizard returned the following error and halted...

We do have two global address lists.  One is named Default Global Address List and the other is Company Name Addresses.

I am not able to browse/edit our public folders using the Public Folder Management Console for some reason.  It indicates it is not connected to a server, and I cannot manually connect to either of our two Exch 2010 HT/CAS/MB servers.
