I get this all the time. It means just what it says -- while mutt was open and doing whatever it thinks it was doing, somebody else came along and adjusted the underlying file(s). So it's possible that, for example, you ran a second copy of mutt and marked an item for deletion, that the current window isn't aware of. The item **should** have a D flag, but the current instance of mutt wouldn't know that. It just knows that something happened.
It's usually a spurious error that indicates you got a new email while mutt was already open. But it's an indication that mutt is aware that something happened, and that it knows it may no longer be an authoritative indication of what your mailbox looks like. --hymie!
