By default outlook displays a notification when you receive an email. As teachers we often don't want this since it will show students the title of our emails as we are connected to a projector. Here's how to turn that off. 

Step-by-step guide

  1. Open the Outlook Program
  2. Click File, then Options
  3. Scroll down to "Message arrival" pane and uncheck "Display a Desktop Alert"
     
    1. I also like to turn off "Play a sound" and "change the mouse pointer"
    2. I prefer to leave the 'Show an envelope icon in the taskbar" because that way, i can see some reminder to check my email"
  4. Click "OK" to save your changes. 
  5. Now, you should no longer receive the desktop alert that shows your email.
