I've just recently started having a problem with my email not showing as read after I view it. I use SPB Mobile Shell but that is just an interface to POutlook. When new mail comes in, SPB MS alerts me. When I click on the icon it takes me to POutlook. I then click on the email and read it. I notice that after clicking OK to exit back to the inbox, the little envelope icon shows it hasn't been read. If I close POutlook, MS still shows unread email. If I read the email a second time it will show as read.
