Email Experiences - Disabling the New Outlook for Windows

This article outlines how to disable the new Outlook for Windows. This will allow the Terminus Outlook Agent to continue to manage signatures in Outlook as expected.

Toggling out of the new Outlook as an End-User:

In the new Outlook for Windows, you'll see a toggle on the top right of your screen.
While the toggle is enabled, if you try to launch classic Outlook for Windows or Windows Mail you'll be automatically redirected to the new Outlook for Windows.

If you toggled into the new Outlook for Windows preview from classic Outlook for Windows, every time you try to launch classic Outlook for Windows you'll be redirected to the new Outlook for Windows preview. You can go back to classic Outlook for Windows by selecting the toggle in the new Outlook for Windows app.

Modifying the Registry Key as an End-User:

1. Make sure you try to launch classic Outlook for Windows from the Windows Start Menu, not the new Outlook for Windows. The new Outlook for Windows has a “New” tag on its app icon. For classic Outlook, select the icon without a “New” tag.
2. From the Windows Start Menu, type “Registry Editor” in the search box and select the Registry Editor app.
3. Navigate to the following path: Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences
4. Scroll to the bottom of the list to and double click on UseNewOutlook.
5. Enter 0 in the Value Data field.
6. Attempt to launch classic Outlook for Windows from the Windows Start Menu.

If you're an admin and want to turn this feature off in the Outlook desktop app for your organization, please review this Microsoft resource.
