I have a 9650 with BIS on Sprint. I get my e-mail through OWA. When I open or mark as read an e-mail on my phone, my Outlook inbox on my desktop is updated accordingly. However, when I open an e-mail on my desktop, my inbox on my phone is not updated to show that the e-mail has been opened. I have to go in an mark as read all of the items, which is a royal pain.
