The first e-mail account I added to Outlook would have a small semi-transparent box pop-up whenever I got a new e-mail. This would have the sender and the first sentence of the bod and fades away in a few seconds. This would happen even if I had Outlook minimized. For some reason my other e-mail accounts don't do this, how do I set it up? The first account uses Exchange Server so I don't know if that's why.
I'm surprised Outlook only does this for the default mailbox.
