If you find the new Outlook interface unappealing and you’re looking to revert back to the classic version, you’re in the right place. This guide will walk you through the necessary steps to control the installation and use of the new Outlook on Windows 10 and 11. You will learn how to configure your system to prevent the automatic switch to new Outlook, block its preinstallation, manage user settings regarding automatic migration, and ultimately install the classic Outlook application.

Step 1: Prevent Users from Switching to New Outlook

The first step is to prevent users within your organization from transitioning to the new Outlook interface. To do this, you will need to modify the registry settings on your Windows machine. Before proceeding, make sure to create a backup of your registry in case you need to revert any changes.

Follow these steps to modify the registry:

  1. Press Win + R to open the Run dialog, then type regedit and hit Enter.
  2. Navigate to the following path: HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Options.
  3. Right-click on the Options key, then select New > DWORD (32-bit) Value.
  4. Name this new DWORD as DisableNewOutlook and set its value to 1 to disable the new Outlook.

This change will ensure that users will not be able to access the new Outlook experience.

Step 2: Block New Outlook Preinstallation on Windows

If you want to prevent new installations of Outlook from occurring altogether, you can disable new Outlook preinstallation on Windows. Again, this requires accessing the registry:

  1. Open the Registry Editor as described above.
  2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Options.
  3. If the Options key does not exist, right-click on the Outlook key and create a new key named Options.
  4. Inside this key, create a new DWORD called DisableOutlookPreinstall and set its value to 1.

With this setting in place, new versions of Outlook will be blocked from being preinstalled on your system.

Step 3: Opt-out of New Outlook Migration

To opt-out of the new Outlook migration, you can set the migration flag in your registry. This avoids any uninvited migration prompts:

  1. In Registry Editor, navigate to: HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook.
  2. Create or modify a DWORD value named MigrationOptOut and set it to 1.

This step ensures you won’t be prompted to migrate to the new interface unexpectedly.

Step 4: Prevent Users from Acquiring New Outlook from Microsoft Store

To completely avoid users from downloading the new Outlook version via the Microsoft Store, you can modify group policies or set registry keys accordingly:

  1. Open the Local Group Policy Editor by typing gpedit.msc in the Run dialog.
  2. Navigate to User Configuration > Administrative Templates > Windows Components > Store.
  3. Enable the setting titled Turn off the Store application.

This will restrict access to the Microsoft Store, preventing any inadvertent installations.

Step 5: Manage User Settings for Automatic Migration

It’s important to manage user settings to avoid automatic migrations to the new Outlook:

  1. In the Registry Editor, navigate once more to HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Options.
  2. Create a DWORD named AutomaticOutlookMigration and set it to 0.

This setting ensures that Outlook will not migrate automatically, maintaining your preferred version.

Step 6: Download and Install Classic Outlook

To restore Classic Outlook after performing the above configurations, you can download it through the following link:

Download Classic Outlook. Follow the installation instructions to complete the setup. Be sure to check your account settings after installation to ensure everything transitions smoothly.

Extra Tips & Common Issues

During this process, keep in mind that some settings might require administrative privileges, especially if you’re part of a corporate network. Additionally, ensure you have the latest updates installed for Windows and Outlook to avoid any compatibility issues. If you encounter any problems, double-check the registry values you’ve set to ensure they’re correct.
