On my old PC Win11/O365 I had Outlook and had the option to try the new Outlook. I did and didn't like it so went back to Outlook classic. I now have a new PC and the O365 rendition now only has the new Outlook and NO option to use Outlook classic. Like many others I do not like the new Outlook and would prefer to use Outlook classic. As an O365 subscriber I believe I should have the choice to use classic Outlook. Is there any way I can download and use Outlook classic ??

    To get the classic Outlook back in your O365 subscription, you may need to check the installation settings and ensure that both classic and new Outlook can be run side-by-side. Starting with Version 2502, new deployments of Microsoft 365 desktop client apps on Windows devices include the new Outlook app by default, but organizations can configure settings to allow for classic Outlook as well.

    If you want to revert to classic Outlook, you can do so by following these steps:

    1. Check Installation Settings: Admins can change the default behavior to include or exclude classic Outlook using the Office Customization Tool or by configuring the XML directly with the Office Deployment Tool.
    2. Remove New Outlook: If new Outlook was already installed, it can be removed without affecting existing installations of classic Outlook. You can find the steps to control the installation and use of new Outlook in the Microsoft documentation.
    3. Policy Settings: Ensure that there are no policies blocking the option to switch back to classic Outlook. If the policy to block the "try the new Outlook" toggle is turned on in classic Outlook, it won't be affected by configuration changes.

    If you are unable to see the option for classic Outlook, it may be due to the specific version of Windows or Outlook you are using, as certain unsupported versions may restrict access to classic Outlook.

    For detailed instructions, you may need to consult your IT administrator or refer to the official Microsoft documentation on managing Outlook installations.
