Answer 1

Hello, thank you for reaching out to Microsoft Q&A.

You can download the Outlook (Classic) version from the official Microsoft website here.

Answer 2

If you cannot find the toggle switch to return to classic Outlook, there are several potential reasons and solutions:

1. Windows Version: Ensure that you are using Windows 10, Build 1809 (17763) or later, as earlier versions may not support the toggle.
2. Outlook Channel: The toggle is available only in certain channels, including the Current Channel, Monthly Enterprise Channel, and Semi-Annual Enterprise Channel (preview).
3. Outlook Version: The toggle is not supported in nonsubscription versions of Outlook, such as Outlook 2021 or Outlook 2019.
4. Account Type: If your classic Outlook profile contains unsupported account types (like POP or on-premises Exchange accounts), the toggle may not be visible.
5. Registry Key: Check the registry setting for HideNewOutlookToggle located at HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\General. If this key is set to 1, the toggle will be hidden. Change it to 0 and restart classic Outlook to see if the toggle appears.
6. Cloud Policy: Verify if there is a policy in the Microsoft 365 Apps admin center that disables the toggle.

If these steps do not resolve the issue, you may want to reach out to Microsoft Support for additional help, providing them with the .etl files from %Temp%\Outlook Logging for further investigation.
