All:

Mountain Lion
Mac Pro Retina 13" maxed out configuration

I have recently transferred my Outlook from previous Mac Pro to this machine. Outlook opens ad runs well, but freezes every time on close. I have tried:

Rebuilding identities
Removing old identity backups
Reinstallation

Also, I recall a thread regarding conflicting preference files but cannot seem to locate it now.

TYIA for any insights into this issue.
