I am using a BES server configuration to connect to my company email. When I first turn on the blackberry (Curve 8310), I can easily delete emails by using the DEL key. After a while, suddenly when I press the DEL key on the BB, it simply changes the message to "Read" status (doesn't open it, just unbolds it) but doesn't delete! From that point on, I can no longer delete messages from the blackberry unless I turn it off, then back on - at which point deleting will work for a short time. Any ideas?
