Per BlackBerry Support: "The BlackBerry Enterprise Server is receiving an OTAFM batch from the BlackBerry smartphone which contains multiple commands. The BlackBerry Enterprise Server should be ignoring all the commands in this batch, but it does not and the BlackBerry Enterprise Server processes the MODIFY_FOLDER command which turns off redirection for the Inbox."

BlackBerry development has been made aware of the problem but has not announced a date for a hotfix to resolve the issue at this time.

Resolution:
re-enable folder redirection for affected BlackBerry smartphone users.
