Turn on or off new message alert pop-up window

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

Outlook Desktop Alert

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.


Tip    If you want to keep a Desktop Alert visible so that you can take more time to read it, rest the pointer on the alert before it fades from view.

To turn on or off Desktop Alerts, do the following:

  1. Click the File tab.
  2. Click Options.
  3. Click Mail.
  4. 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.

You can also turn off Desktop Alert when one appears on your screen. Click the down arrow on the alert, and then click Disable New Mail Desktop Alert.

  1. To change the transparency of Desktop Alerts or how long they are visible, click 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 are 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.
