  3. Select Hide When Minimized. A check mark before Hide When Minimized indicates that Outlook is set up to minimize to the system tray.

  4. In Outlook, select Minimize. Outlook disappears from the taskbar and reappears on the system tray.

Use the Registry to Minimize Outlook

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

  1. Open the Registry Editor. Go to the Windows taskbar and, in the Search box, enter regedit. Select regedit Run command from the search results.

  2. In the Registry Editor window, go to the HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences folder.
