So my Outlook currently has 4 unread messages. I click on the Messages panel, click on Outlook and my inbox opens, and correctly I have 4 unread messages. I do not open any of them, so they are still unread.
Going back to the home screen, the sliding panel now says zero.
i.e. this is really showing the number of unread messages since you last opened the mailbox, not the total number of unread messages.
is this just my build? I'm running one of the Ricky/Kavana builds, number 4 I think.
