Switching back to old Outlook turns off the new Outlook preview toggle in the settings menu. If you are wondering how do you switch back to old outlook, the process is simpler than you might think. Many users find the new Outlook interface confusing or missing features they rely on daily.
This guide walks you through every step to revert to the classic Outlook experience. Whether you are using Outlook for Windows or the web version, we have you covered. Let’s get started with the quickest methods first.
Why Switch Back To Old Outlook
The new Outlook preview has been redesigned for a modern look. However, it lacks some critical features that power users depend on. For example, offline access, custom add-ins, and certain folder management options are limited or missing.
Many users also report slower performance or compatibility issues with third-party tools. If you rely on shared mailboxes, PST files, or advanced rules, the old Outlook is often more reliable. Understanding why you want to switch helps you confirm the right steps.
Common Reasons Users Revert
- Missing offline support for emails and calendars
- Incompatibility with legacy add-ins or plugins
- Confusing navigation and hidden settings
- Performance lags or frequent crashes
- Limited customization for toolbars and views
Whatever your reason, the switch back is straightforward. Just follow the instructions below based on your Outlook version.
How Do You Switch Back To Old Outlook
This is the exact heading you need to find the toggle. The setting is located inside the Outlook options menu. Here is the step-by-step process for the Windows desktop app.
Step 1: Open Outlook And Access Settings
- Launch Microsoft Outlook on your computer.
- Click on File in the top-left corner of the ribbon.
- Select Options from the left-hand menu. This opens the Outlook Options window.
- Navigate to the General tab if it is not already selected.
You should now see a section labeled “Outlook Preview.” This is where the magic happens.
Step 2: Turn Off The New Outlook Toggle
- Look for the checkbox or toggle that says “Try the new Outlook.”
- Uncheck the box or switch the toggle to the off position.
- A prompt may appear asking you to confirm. Click Yes or OK.
- Restart Outlook for the changes to take effect.
After restarting, Outlook should open in its classic interface. If you still see the new design, repeat the steps and ensure the toggle is fully disabled.
Step 3: Verify The Old Outlook Is Active
Check the top menu bar. You should see the traditional ribbon with tabs like Home, Send/Receive, and Folder. Also, look for the classic navigation pane on the left side. If these elements are present, you have successfully switched back.
If the toggle option is missing or grayed out, your organization may have enforced the new Outlook via group policy. In that case, contact your IT administrator for assistance.
Switching Back On Outlook For Mac
Mac users have a similar process, though the menu names differ slightly. Here is how to revert on macOS.
Steps For Outlook For Mac
- Open Outlook and click on Outlook in the top menu bar.
- Select Preferences from the dropdown.
- Click on General under the Personal Settings section.
- Find the option labeled “Use the new Outlook” and uncheck it.
- Close the preferences window and restart Outlook.
The classic interface should return immediately. If not, try quitting Outlook completely and reopening it.
Reverting From Outlook On The Web
The web version of Outlook also has a new look. If you want to switch back to the classic web interface, follow these steps.
Steps For Outlook Web App (OWA)
- Log in to your Outlook account via a browser.
- Click on the Settings gear icon in the top-right corner.
- Scroll down and select View all Outlook settings.
- Go to General and then click on Outlook preview.
- Toggle off “Try the new Outlook” and click Save.
- Refresh the page to see the classic web interface.
Note that the web version may not have all classic features. Some elements are permanently updated by Microsoft. However, the layout and navigation should feel more familiar.
Troubleshooting Common Issues
Sometimes the switch back does not work as expected. Here are solutions to frequent problems.
The Toggle Is Missing Or Grayed Out
If you cannot find the toggle, your account might be managed by an organization. IT admins can enforce the new Outlook for all users. Contact your help desk to request the classic version.
Another possibility is that you are using an older version of Outlook. Update to the latest build and check again. Microsoft sometimes moves the toggle location in updates.
Outlook Still Shows New Interface After Toggle Off
This can happen if the setting did not save properly. Try the following:
- Close Outlook completely using Task Manager (Ctrl+Shift+Esc).
- Restart your computer to clear any cached settings.
- Open Outlook and check the toggle again. Ensure it is unchecked.
- If the problem persists, repair your Office installation via Control Panel.
Missing Features After Switching Back
Some users notice that certain features are still missing even in classic mode. This is usually because Microsoft has deprecated those features. For example, the old “Clutter” folder is replaced by “Focused Inbox.”
If you need a specific feature that is gone, consider using a third-party add-in or contacting Microsoft support for alternatives.
What Happens To Your Data When You Switch
Switching back does not delete any emails, contacts, or calendar items. Your data remains intact. However, any settings or customizations made in the new Outlook may be lost. For instance, if you rearranged the navigation pane in the new version, those changes will not carry over.
It is a good idea to back up your Outlook data file (PST or OST) before switching. This ensures you have a recovery option if something goes wrong.
How To Back Up Your Outlook Data
- Go to File > Open & Export > Import/Export.
- Select “Export to a file” and click Next.
- Choose “Outlook Data File (.pst)” and click Next.
- Select the folders you want to back up and choose a save location.
- Click Finish to create the backup.
Store the PST file in a safe place. You can import it later if needed.
Alternatives To Switching Back
If you cannot switch back due to IT policies, there are workarounds. You can try using Outlook in compatibility mode or install an older version of Office. However, these methods are not officially supported and may cause security risks.
Another option is to use a different email client altogether. Thunderbird or eM Client offer classic interfaces and support Outlook data. But they require manual setup and may not integrate with Microsoft 365 features.
Using Outlook With Classic Add-Ins
Some add-ins can restore classic functionality. For example, “Classic Outlook Menu” brings back the old ribbon layout. Search for such tools in the Office Add-ins store. Be cautious with third-party add-ins as they may affect performance.

Final Tips For A Smooth Transition
Before switching, note any custom settings you have in the new Outlook. Take screenshots of your layout and rules. This helps you reconfigure the classic version faster.
If you are using multiple devices, repeat the process on each one. The setting is per device and does not sync across computers. Also, check for updates to Outlook after switching, as Microsoft may have fixed bugs in the classic version.
Remember that the new Outlook preview is still in development. Some features may improve over time. If you decide to try it again later, you can always toggle it back on.
