Internet Explorer Envelope Icon

[Mampara]

When I received an e-mail I was alerted by an envelope icon, but this has disappeared for some reason.
Can anyone please advise how I can restore it?

What email client do you use? Outlook?

If so, go to Tools - Options - Prefernces - E Mail Options and make sure that there is a tick in "Display a notification when new mail arrives"
