How to Turn Off Desktop Alerts in Outlook
A Desktop Alert is a notification that appears on your desktop when you receive a new e-mail message, meeting request, or task request. Desktop Alerts are turned on by default.
- Click the File tab.
- Click Options.
- Click Mail.
- Scroll down a little ways and under Message arrival, clear the Display a Desktop Alert check box. To suppress other notifications such as playing sounds, changing the mouse pointer, or displaying an envelope icon in the taskbar, clear the respective check boxes for those functions.
To turn Desktop Alerts back on, simply repeat the steps above, but this time in step 4, check the functions you want to enable.
