Same Problem
Hi, I have exactly the same issue, and I am glad to see your post. I posted something on this a while back, but did not articulate the problem as clearly as you did. I have gone back and forth with support on this. They gave me the standard "clear your cache" procedures, but I suspect it is more of an IMAP glitch, since in my case, the emails that are "left over" in the inbox on MM do show up in my synced folders as well on MM, so the syncing is working just fine. I too, have the same experience where, once you fix one, all the rest get fixed as well. I expressed all this to the MM support, so (I hope) they are clearly aware of the situation. Once in a while, if I am logged out of MM, and perform some action on emails either in Mail.app or the iphone, when I log back in, I will occasionally see the inbox as it should be, i.e., empty, so apparently the issue doesn't happen 100% of the time, but it happens more often than it should. If others are experiencing this, please speak up.
