OK, so I only started using mac mail app a couple of years ago and I only use it for business stuff, which is small, so I get almost no junk and a small flow of incoming emails. Anyway, I notice I have 400+ items in the trash can, so instinctively I R click & 'erase deleted items'. Nothing. No warning, no spinning wheel, it just asks me if I want to delete the trash Items, but when I click yes, it does nothing. I jumped on Google and found a few threads saying rebuild the mailbox. Did that. Nothing. Restarted, you guessed it - nothing. It just seems to ignore my request completely. Any help? Cheers.
