I have a Curve 8900.
I am on BES.
I downloaded the BES Mailbox App so that it separates my work email from my personal email.
Everytime I send a message from my work, it will show up as a NEW message in my inbox (and have a check next to it).
Basically, in my BES mailbox, its showing all of the messages (including sent messages).
HOWEVER, I saved the settings in the e-mail that say HIDE sent messages. Yet it still shows............
