This guide will walk you through every method, from simple toggles to registry edits, so you can switch back in minutes.

Microsoft rolled out the new Outlook for Windows as a replacement for the classic Mail and Calendar apps. While it offers modern features, some users find it slower or less intuitive. The good news is that you can disable it and return to the old version without losing your data.

How Do I Turn Off New Outlook

This section covers the most common ways to turn off the new Outlook. Depending on your setup—whether you use the standalone app or the one bundled with Microsoft 365—the steps may vary slightly. Follow the method that fits your situation.

Method 1: Using The Toggle Switch In The New Outlook App

The easiest way to revert is through the built-in toggle. This option appears in the new Outlook itself, letting you switch back instantly.

  1. Open the new Outlook app on your Windows computer.
  2. Click on the File menu in the top-left corner.
  3. Select Options from the left sidebar.
  4. Look for a section labeled General or Mail.
  5. Find the toggle that says Try the new Outlook or Use the new Outlook.
  6. Turn the toggle off. The app will prompt you to restart.
  7. Click Restart Now to apply the change.

After restarting, the classic Outlook interface should load. If the toggle is missing, your version may not support it—try the next method.

Method 2: Disabling New Outlook From The Classic Outlook App

If you still have the classic Outlook installed, you can disable the new version from there. This works for Microsoft 365 subscribers.

  1. Open the classic Outlook app (the one with the ribbon interface).
  2. Go to File > Options.
  3. In the General tab, look for Enable the new Outlook.
  4. Uncheck the box next to it.
  5. Click OK and restart Outlook.

This method ensures the new Outlook won’t launch again. If you don’t see this option, your classic app might be outdated—update it first.

Method 3: Using Windows Settings To Remove New Outlook

Windows 11 and 10 let you manage default apps and remove the new Outlook entirely. This is a more permanent solution.

  1. Press Windows + I to open Settings.
  2. Go to Apps > Installed apps.
  3. Search for Outlook (new) in the list.
  4. Click the three dots next to it and select Uninstall.
  5. Confirm the uninstallation.

Note: Uninstalling the new Outlook does not affect your classic Outlook or email accounts. You can always reinstall it later from the Microsoft Store.

Method 4: Reverting Via The Microsoft 365 Admin Center

For business users or administrators, you can turn off the new Outlook for an entire organization. This requires admin credentials.

  1. Log in to the Microsoft 365 Admin Center.
  2. Go to Settings > Org settings.
  3. Select Outlook from the list.
  4. Under New Outlook, toggle the option to Off.
  5. Save the changes. Users will see the classic version on their next restart.

This method is ideal for IT admins who want to standardize the experience across their team.

Common Issues After Turning Off New Outlook

Sometimes the switch doesn’t go smoothly. Here are problems you might face and how to fix them.

Issue 1: The Toggle Doesn’t Appear

If you cannot find the toggle, your Outlook version might be too new or too old. Update to the latest release or check if your organization has disabled the option.

Issue 2: Classic Outlook Won’t Open

After turning off the new version, the classic app might fail to launch. Try repairing Office from the Control Panel or reinstalling it.

Issue 3: Emails Are Missing

Your messages should remain intact, but if they disappear, check your account settings in the classic app. Re-add your email account if needed.

Step-By-Step Guide For Windows 11 Users

Windows 11 has a slightly different interface. Here is a tailored guide for turning off the new Outlook.

  1. Click the Start button and type Outlook.

  3. Scroll down to Terminate and click it to close the app.
  4. Open the classic Outlook from the Start menu.
  5. Go to File > Options > General.

Using Registry Editor As A Last Resort

  1. Press Windows + R, type regedit, and press Enter.
  2. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences

  5. If it doesn’t exist, create a new DWORD (32-bit) with that name.
  6. Close the editor and restart Outlook.

This method disables the new Outlook toggle entirely. To re-enable it later, change the value back to 1.
