| | Re: "Show Filed" messages problem
With "show filed messages" set to off, you will see the messages in the message list, but since the messages you refer to are governed by rules to move them as they come in, they will appear with a folder icon beside them on the left. If you delete them from the message list, you are deleting them from the folder, so you just need to remember that! If those folders are not synced, the messages won't appear on the device, as you probably now know!
