How Do You Go Back To The Old Outlook – Revert To Classic Outlook

Going back to the old Outlook involves switching off the new Outlook toggle in the upper-right corner. If you’ve recently updated and miss the classic interface, this guide will show you exactly how do you go back to the old outlook without losing your emails or settings. Many users find the new design confusing or slower, so reverting is a common need.

Microsoft rolled out a new Outlook for Windows, but not everyone likes the change. The classic version still works well and feels more familiar. You can switch back in just a few clicks, and we’ll walk you through every step. No technical skills required.

How Do You Go Back To The Old Outlook

The quickest method uses the toggle switch in the Outlook app. This option appears in the top-right corner of the window. Look for a slider labeled “Try the new Outlook.” If you see it, you can turn it off to revert instantly.

Sometimes the toggle is hidden or missing. Don’t worry—there are other ways to go back. We’ll cover all scenarios, including registry edits and reinstalling the classic version.

Step 1: Locate The Toggle Switch

Open Outlook and check the upper-right corner. You’ll see a slider icon next to your profile picture or account name. Click it to disable the new Outlook.

  • If the toggle is blue, the new Outlook is active.
  • If it’s gray, you’re already using the classic version.
  • Click once to switch off.

After clicking, Outlook may ask you to confirm. Select “Yes” or “Revert.” The app will restart automatically in the old interface.

Step 2: Confirm The Change

Once Outlook restarts, check the top bar. You should see the classic ribbon with File, Home, Send/Receive, and Folder tabs. If you see a simplified toolbar, the switch didn’t work—try again.

Sometimes the toggle reappears after an update. If that happens, repeat the steps. Microsoft may push updates that re-enable the new Outlook, so keep an eye on it.

Alternative Methods To Revert

If the toggle is missing or grayed out, use these backup options. They work for most versions of Outlook 2016, 2019, 2021, and Microsoft 365.

Method 1: Use The Registry Editor

Editing the Windows registry can force Outlook to use the classic version. This method is safe if you follow the steps carefully. Back up your registry first.

  1. Close Outlook completely.
  2. Press Windows + R, type “regedit,” and hit Enter.
  3. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences
  4. Look for a DWORD named “NewOutlookToggle.” If it doesn’t exist, create one.
  5. Set the value to 0 (zero) to disable the new Outlook.
  6. Restart Outlook.

If the value is already 0, try setting it to 1 and then back to 0. This resets the toggle. Some users report that this works even when the slider is hidden.

Method 2: Reinstall Classic Outlook

If registry edits don’t help, uninstall and reinstall Outlook from your Microsoft account. This ensures you get the classic version without the new toggle.

  • Go to Settings > Apps > Installed apps.
  • Find Microsoft 365 or Office, then select Modify.
  • Choose Quick Repair first. If that fails, try Online Repair.
  • After repair, open Outlook and check the toggle.

Reinstalling resets all settings. You’ll need to reconfigure your email accounts, but your data stays safe in the cloud.

Why Users Prefer The Old Outlook

The new Outlook integrates with web apps and has a modern look. But many people find it slower and less intuitive. Classic Outlook offers offline access, better folder management, and customizable toolbars.

Common complaints about the new version include missing features like shared calendars, offline search, and advanced rules. If you rely on these, reverting makes sense.

Performance Issues

The new Outlook can lag on older computers. It uses more memory and loads slowly. Classic Outlook runs smoothly even on modest hardware.

Familiar Interface

Long-time users know where everything is in the classic layout. The new design moves buttons around, which wastes time. Sticking with the old version boosts productivity.

Troubleshooting Common Problems

Sometimes the toggle doesn’t appear at all. This happens if your organization uses group policies or if you’re on an older Outlook build. Here’s how to fix it.

Toggle Missing Entirely

Check for updates first. Go to File > Office Account > Update Options > Update Now. After updating, the toggle should show up.

If it’s still missing, your IT admin may have disabled it. Contact your support team and ask them to enable the toggle via Group Policy. You can also try the registry method above.

Outlook Keeps Switching Back

Some users report that Outlook reverts to the new version after a restart. This is often caused by a Microsoft update. To prevent this, disable automatic updates temporarily.

  • Go to File > Office Account > Update Options.
  • Select “Disable Updates.”
  • Reapply the registry fix to lock in the classic version.

Remember to re-enable updates later for security patches.

How To Stay On Classic Outlook Permanently

Microsoft plans to phase out the classic Outlook eventually. But for now, you can keep using it. Here are long-term strategies.

Block The New Outlook Update

Use the registry to prevent the new Outlook from installing. Add a DWORD named “NewOutlook” under HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Setup and set it to 0.

This tells Outlook not to offer the new version. It works for most Microsoft 365 subscribers.

Use Outlook Web Access (OWA)

If you’re forced to use the new Outlook, try OWA instead. It’s similar to the new desktop app but runs in a browser. You can access it at outlook.office.com.

OWA has most features of the new Outlook without the desktop app’s bugs. It’s a good fallback if you can’t revert.

Final Tips For A Smooth Transition

Before reverting, export your settings and signatures. This saves time if you need to reconfigure things later. Go to File > Options > Advanced > Export.

Also, note that some add-ins may not work in the new Outlook. If you use third-party tools, test them after switching back. Classic Outlook has better add-in compatibility.

If you’re on a work computer, talk to your IT department before making changes. They may have policies that prevent reverting. In that case, ask them to adjust the settings for you.

Remember, the toggle method is the easiest. Use it first before trying registry edits or reinstalls. Most users can go back in under a minute.

We hope this guide answered your question about how do you go back to the old outlook. The process is simple, and you have multiple options. Stick with what works best for you.

If you encounter issues, Microsoft’s support forums have detailed threads. Search for “classic Outlook revert” to find solutions from other users. You’re not alone in this preference.

Finaly, keep your Outlook updated even if you stay on the classic version. Security patches are important. Just disable the new Outlook toggle after each major update to stay in control.
