During update to Mavericks, Outlook failed to close and locked up.  The Mavericks update was successful, but I have been unable to recover the Main Identity.  I am using a Mac Air which only has 128 GB disk.  I have read that at least 300 GB should be used to recover the identity.  Is there a way to use an external disk to perform recovery?  I read where one individual used a Mac Pro to perform the recovery, but I believe that  means you must have Outlook installed there.  And how would you access the Main Identity from the second computer or with an external drive?
