Mobile devices that connect to Groupwise 2012 Webaccess fail to load the mailbox. Viewing the webadmin webpage show only devices using css or simple interfaces correctly connect with the mailboxes.
iPad and Kindle Fire are configured in webacc.cfg to use the mobile interface.

The fix: tomcat6 and webacc.cfg strings were scattered throughout the webacc.cfg file. I removed them from anywhere statements were not commented out.
The iPads are connecting to the mailboxes.
