Ever since doing OS X 10.8 updates, a pair of machines with Outlook refuse to look back further than 2 weeks during e-mail searches. Spotlight settings all look OK. I even forced an index deletion/re-creation with "sudo mdutil -E". Index does go away, but comes back the same way, only being able to search the last 2 weeks worth of items (and there are items going back years it should be finding). Mailbox size is right around 1.9 GiB. Ideas?
