How to minimize Outlook to System Tray in Windows 10/8.1

If you use Microsoft Outlook on Windows 10/8.1, as your default email client, then you may have noticed that, when you minimize Outlook, it minimizes to the taskbar and continues to occupy space. This can create a problem if you have too many programs open in the taskbar. If you have it open all the time, then rather than having it sit in the taskbar, you may wish to minimize Outlook to the system tray, or notification area. If this is the case, you can do it as follows.

Minimize Outlook to System Tray

Using UI

Minimize Outlook to System Tray

To minimize outlook to system tray, right-click on the system tray icon of Outlook. Next, select  Hide When Minimized from the menu offered.

Using Registry

If you wish to make the change by editing the Windows Registry. After you have created a system restore point, open regedit to open the Registry Editor,  and navigate to the following key:
