    In new Outlook, select the toggle in the upper-right corner and choose Switch back to classic Outlook to make classic Outlook open by default again.^1^

    Switch back

    1. Open new Outlook.
    2. Select the New Outlook toggle in the upper-right corner.
    3. Choose Switch back to classic Outlook.
    4. Complete or skip the feedback prompt. Classic Outlook should open.

    Choose Use classic Outlook this time only if you want a one-time launch; future launches will continue redirecting to new Outlook.^1^

    If the toggle is missing

    1. Open Start and search for Outlook.
    2. Launch Outlook (classic), not the Outlook icon marked New.
    3. If Outlook (classic) is not listed, install it using Microsoft’s classic Outlook installer. Many newer Windows devices include new Outlook but not classic Outlook.^2^
    4. After installation, search for Outlook (classic) again and open it.

    If classic Outlook is installed but still redirects to new Outlook, Microsoft documents this recovery:

    1. Close Outlook.
    2. Search Windows for Registry Editor and open it.
    3. Go to: Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences
    4. Double-click UseNewOutlook and set Value data to 0.
    5. From Start, launch Outlook (classic).^1^

    Editing the registry incorrectly can affect Office behavior; change only this documented value.

    For a work or school account, a missing toggle can also mean that your organization disabled it. In that case, contact your Microsoft 365 administrator.^3^

    Hello @Alberto Cohen

    If you're using New Outlook for Windows and want to return to Classic Outlook, you can usually do it directly from the app:

    • Open New Outlook.
    • In the top-right corner, locate the New Outlook toggle.
    • Turn the toggle Off.
    • Select Switch back to classic Outlook when prompted.
    • Outlook will close and reopen in the classic version.

    If you don't see the toggle

    • Make sure Classic Outlook is installed on your PC. In the Start menu, look for "Outlook (classic)".
    • If you're using a work or school account, your organization's IT administrator may have disabled the toggle. In that case, contact your IT support team.
