I have a folder on 3 different email servers that contains notifications of forum replies. I want to use a Smart Mailbox to view them all in one place. However, when I go to set this up the Smart Mailbox won't save a folder within my GMail account, only that ONE GMail account. I have 2 other GMail accounts that work just fine.
See, it is selected, and now I save it.
Once saved, I go back in, and now no mailbox is selected.
I really don't know what else to try, this isn't a deal breaker but ALL of my other accounts work. I've tried deleting my Google accounts from the computer (and iCloud) then loading them back but that doesn't work.
