Outlook Icon on Taskbar or Notification area (System Tray)

Outlook 2016
Like most Windows applications, when the Outlook application is open and running, it displays a corresponding icon on the Taskbar, where you can pin it to launch the application more quickly in the future. Even if you use custom parameters to start the Outlook application, you can still pin the corresponding icon to the Taskbar:

In addition, the running Outlook application displays the icon in the Notification area (sometimes called the system tray or systray):

  1. If you don't see the Outlook icon in the notification area after you start Outlook, the icon may be hidden. Click the Expand button (up arrow) on the left side of the Notification area to expand it and also to show all hidden icons:

  2. Instead of the Outlook icon, you may see a closed envelope icon, indicating that you have received new messages:

The default settings minimize Outlook to the Taskbar, but you can make settings to minimize it to the System Tray (Notification area).

To enable this feature, follow these steps:

   1.   Right-click on the Outlook icon in the System Tray:

   2.   Select Hide When Minimized from the menu.

Now, when you minimize Outlook, it minimizes to the Notification area instead of the Taskbar. This feature frees up space on the Taskbar for other applications.
