Missing emails
I sat down to begin work this morning and all my emails from may and june are gone. In fact, when I look at all the emails they appear to be junky ones that were never opened but not deleted. Is there a way to retrieve these missing emails? I've checked spotlight and nothing is set in privacy there. I've checked all the other folders in the mail window and trash and junk. no luck. I have gone to the mailbox menu and chosen synchronize and chosen rebuild. I am now getting new ones but still missing all of the last two months. help!?
