My toggle does not work. Will not revert when toggled.

I have tried to edit the Reg entry (manually) and I have tried to insert a Reg entry by CMD.

 reg add "HKCU\Software\Microsoft\Office\16.0\Outlook\Options\General" /v HideNewOutlookToggle /t REG_DWORD /d 00000001 /f

I have uninstalled it. Any ideas?

    Hi @Jarrod Davis ,

    Welcome to our forum!

    Have you ever used the Classic version of Outlook before?

    If not, for example, the New Outlook for Windows is pre-installed on a new device and doesn't come with classic Outlook, you can try to install Classic Outlook for Windows. More information: You can't open classic Outlook on a new Windows PC.

    If you have switched to New Outlook from Classic Outlook, it's suggested that you could try the below registry:

    1. From the Windows Start Menu, type “Registry Editor” in the search box and select the Registry Editor app.
    2. Navigate to the following path: Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences
    3. Scroll to the bottom of the list to and double click on UseNewOutlook.
    4. Enter 0 in the Value Data field.
    5. Attempt to launch classic Outlook for Windows from the Windows Start Menu. (Tip: Remember to choose the app icon that doesn't have a New tag.)

    (Note: Serious problems can occur if you modify the registry incorrectly. Before making changes, back up the registry to restore it in case something goes wrong.)

    Hope to help you!
