I've tried the "reconcile now" option and that doesn't seem to make a difference.
As I read the User's Guide, Hide Filed Messages should work for more than just messages filed on the BB:
"If email messages are sent to your BB device from specific desktop email program folders, and in the general messages options, you set the Hide Filed Messages option to Yes, new messages that are sent to your device should be filed automatically, and might not appear in your messages list".
I like their choice of the words should be
, and might not
. I'm guessing this may be a timing issue. Of course one workaround would be to change my outlook rule to make a copy of the message in the subfolder, then delete the original message. This wouldn't work for me, because it would clog up my deleted items folder with duplicate emails. Right now I'm living on the fringe of my allocated space on our server, and can't take the hit of lost space.
