I'm having a similar issue. Running with pop, but set so my Eco pulls email every 10 minutes and leaves them on the server while the desktop deletes them when retrieving. The rub is that once the email is retrieved to the phone, if the desktop retrieves and then deletes from the pop server, I can no longer forward or reply to the email on the cell, even though it is sitting right there. A bubble comes up that says the email is not available or something along those lines. If the email has been downloaded to the phone, I want to be able to manipulate it at my leisure.
