I switched from the 9630 to a 8530 and am connected to BESX 5.0. On the 9630 there was an icon on the blackberry that said desktop and it was only BES email.
I also had a setting the the mail options that said inbox setting and would let me choose what mail i wanted to see in the messages folder.
On my 8530 i do not have either of these options. Is it a phone OS difference or a BESX issue? I am getting my mail from my Exchange server so not sure where to look.
