I will open Outlook 2003 and it will download all my mail. As soon as I click on an email message I will hear that "pop" sound and see the icon appear in the tray. I can't right click on it and when I single or double click it dissapears.
I would like to know what it is and why it's started happening, not to mention how to stop it.
I have attached an image showing what it looks like.
