all of a sudden outlook search can't find some of my contacts, some it finds, the contacts are in the addressbook and i can get to them by sending an email and opening the contact card that way, but search won't work. i haven't upgraded outlook or using it with the cloud, it just stopped all of a sudden. when i search via spotlight the contact comes up with " outlook cannot open the file because it is not associated with the default identity" what can i do?

i am using osx 10.7.5
