So I know there's a known issue with BES folders and the current 4.0.219 release of the 7100g software.
However that issue is that BES folders dissapear and you get only Webclient folders instead...happened to me before, fine.
So anyway, I'm chugging along now I see both my BES folders and my Webclient folders perfectly fine. HOWEVER...my new problem is that when I click a message, go to File, click to a folder and then select it...the message doesn't seem to move!!
If I move the message to any folder in Outlook it wirelessly reconciles and the message dissapears from my BB inbox (I hide filed messages).
So for some reason, although the functionality is working the Blackberry is unable to actually file messages itself. I see the folders perfectly fine and I tried deleting the Webclient service book to no avail.
