I'm going to try and articulate this the best that I can. The way that I thought the feature would work is actually pretty simple - if you flagged an email on your device, webmail, or desktop client, then the mail would show up in the Flagged box on iOS regardless of what folder it is in (the same way that any mail client works, really). In Gmail, "flags" = "stars". In Exchange, "flags" = "for followup" iOS 5: Flagging mail in Exchange = marked for followup in exchange Flagging mail in IMAP (Gmail) = starred on gmail No aggregation of flagged messages in iOS. You could access the "starred" folder in gmail, however iOS 6: Flagging mail in Exchange = flagging in exchange, only shows in flagged box in iOS if the message is in Inbox Flagging mail in IMAP (Gmail) = starred on gmail, only shows in flagged box in iOS if the message is in Inbox So basically this feature is worthless if you move mail into folders that are not the inbox (this is extremely common among business users. Most of us do not let everything simply flow into our inbox and leave it there for eternity. We move it to folders to stay organized). Here's how it should work: Mail comes in I flag mail I may or may not move mail to non-inbox folder ("family" for example) Regardless, mail shows up in "Flagged" in iOS Is this really that hard, Apple?
