Office 365 (Outlook 2016 | Outlook 2013) - Turn new message alert pop-up on or off

A Desktop Alert is a notification that appears on your desktop when you receive a new email message, a meeting request, or a task request. By default, Desktop Alerts are turned on.

The information displayed in a Desktop Alert varies depending on the item that you receive in your Inbox.

  • Email message
    Displays the name of the sender, the subject, and the first two lines of the message. A Desktop Alert doesn't display the contents of an encrypted or digitally signed message. To view the message, you must open it. 

  • Meeting request
    Displays the sender, subject, date, time, and location of the meeting. 

  • Task request
    Displays the sender, subject, and start date of the assigned task.

  1. On the File tab, choose Options > Mail.

  2. Under Message arrival, select or clear the Display a Desktop Alert check box. 

    Note: 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. 

  3. To change the transparency of Desktop Alerts or how long they're visible, choose Desktop Alert Settings.

When Desktop Alerts don't appear

Desktop Alert notifications don't appear during the initial synchronization of an email account or when you request a manual Send/Receive. 

Also, if you're using message rules and a new message is moved out of the default account inbox, you might not receive a Desktop Alert notification, or the Desktop Alert notification might not appear for the full duration of time that you configured in the settings for the Desktop Alerts feature.
