High priority mail sounds 3 annoying loud beeps

When I receive a message which is marked with high priority, Outlook plays 3 loud beeps. As I often wear a headset, it really hurts my ears.

How can I disable this annoying sound?

The 3 loud beeps are probably caused by the Cisco Unity ViewMail add-in. You can disable this option (without affecting any other functionality of the Cisco utility) via;

  • Outlook 2007 and previous
    Tools-> ViewMail Options…-> tab Notification
  • Outlook 2010
    tab Add-ins-> ViewMail Options-> tab Notification

Cisco Unity ViewMail Notifications
Here you can also disable the “You have voice mail” notification.

Rules

If you actually like this kind of notification but you don’t have the Cisco Unity ViewMail add-in, then you could still create a rule to play a specific sound when a message with high priority comes in. You can basically select any wav-file for this.

Note: If you get a beep sound for each message that comes in, then take a look here.
