If your Windows 10 taskbar is getting crowded, but you prefer to keep Microsoft Outlook open all the time, you can remove it from the taskbar and hide it by minimizing it to its system tray icon.

These instructions apply to Outlook 2019, Outlook 2016, Outlook 2013, and Outlook 2010.

Outlook: Always There, Yet Out of Sight

If you have Outlook open all day, it is more of an inventory in Windows than an application. It should not occupy a place in the taskbar when you are not currently working in it and it is minimized. Instead, Outlook's place is in the system tray, where it is readily accessible but not in the way.

Minimize Outlook to the System Tray

To minimize Outlook to its icon in the Windows system tray:

  1. Right-click Outlook icon in the system tray with the right mouse button.

  2. Make sure Hide When Minimized is checked in the menu that appears. If Hide When Minimized is not checked, select it from the menu.

When you do this, Outlook disappears from the taskbar and reappears on the system tray.

Using Registry to Minimize Outlook

If you prefer to make the change using the Windows Registry, first create a system restore point and then

  1. Open the Registry Editor by typing regedit in the search box on the taskbar. Select regedit Run command from the search results.

  2. In the Registry Editor window, go to the following location: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Preferences

  3. Click on MinToTray to open the Edit DWORD dialog.

  4. In the Value Data field, place a 1 to minimize Outlook to the system tray. (Typing a 0 minimizes Outlook to the Taskbar.)

What to Do If Outlook Still Shows in the Task Bar

If you can still see the Outlook icon in the Windows taskbar, it may be pinned to it.

To remove a closed or minimized Outlook from the taskbar:

  1. Right-click Outlook in the taskbar.

  2. Select Unpin from taskbar if you see that option in the menu.

Restore Outlook After It Has Been Minimized to the System Tray

To open Outlook again after it has been hidden on the system tray and disappeared from the taskbar, just double-click the Outlook system tray icon.

You can also click on the Outlook system tray icon with the right mouse button and select Open Outlook from the menu that appears.

Make Sure the Outlook System Tray Icon Is Visible

To unhide and make visible the Outlook icon in the main system tray:

  1. Click the Show hidden icons arrowhead in the system tray.

  2. Grab the Microsoft Outlook icon from the expanded tray with the mouse.

  3. Holding the mouse button down, drag it to the main system tray area.

  4. Drop the icon by releasing the mouse button.

To hide the Outlook icon, drag it to the Show hidden icons arrowhead.

These steps also work with earlier versions of Outlook.
