Many users prefer the classic design because it feels more intuitive and less cluttered. This guide will walk you through every step, from checking your current version to reverting settings permanently.
Microsoft redesigned Outlook for Mac in 2020, introducing a new interface that matches the modern look of other Office apps. While the update brought improvements, it also removed some features and changed the layout. If you miss the old toolbar, menu bar, or navigation pane, you can switch back easily.
Before you start, make sure your Outlook is up to date. The option to switch is available in Outlook for Mac version 16.42 and later. If you are running an older version, you may need to update first. Let’s get into the details.
How To Switch To Old Outlook Mac
The process to revert to the classic interface is straightforward. Microsoft includes a toggle in the settings that lets you choose between the new and old designs. Here is how to access it.
Step 1: Open Outlook Preferences
Launch Outlook on your Mac. Click on the Outlook menu in the top-left corner of your screen. From the dropdown, select Preferences. This opens a window with various settings categories.
Step 2: Find The General Settings
In the Preferences window, look for the General icon. It is usually the first option in the list. Click on it to open the general settings panel.
Step 3: Locate The Appearance Section
Scroll down until you see the Appearance section. This is where you control the visual style of Outlook. You will see a checkbox labeled Use the new Outlook.
Step 4: Uncheck The Box
Uncheck the box next to Use the new Outlook. A confirmation dialog may appear, asking if you want to switch. Click Restart Now to apply the change. Outlook will close and reopen automatically with the old interface.
Step 5: Verify The Change
After restarting, check the menu bar and toolbar. You should see the classic layout with familiar icons and menus. If not, repeat the steps or check for updates.
That is all there is to it. The switch happens instantly, and your emails, calendars, and contacts remain unchanged. No data is lost during the process.
Why Switch Back To The Old Outlook?
Many users find the new Outlook for Mac confusing or slow. The classic version offers several advantages that make it worth switching back.
- Familiar Menu Layout: The old interface has a traditional menu bar with File, Edit, View, and other options. This makes navigation faster for long-time users.
- Customizable Toolbar: You can add or remove buttons from the toolbar in the classic version. The new Outlook limits customization options.
- Better Search Functionality: The old search bar is more powerful and allows for advanced queries. The new search is simplified but less effective for power users.
- Faster Performance: Some users report that the old Outlook runs smoother on older Macs. The new version can be resource-intensive.
- Full Sync With Exchange: The classic version supports all Exchange features, including shared mailboxes and public folders. The new Outlook has limitations in this area.
If you rely on advanced features like rules, categories, or custom views, the old Outlook is often more reliable. The new version is still evolving, and some functions are missing.
Common Issues When Switching
While the process is simple, you might encounter a few problems. Here are the most common issues and how to fix them.
Issue 1: The Option Is Grayed Out
If the Use the new Outlook checkbox is grayed out, it means your version does not support the switch. Update Outlook to the latest version via the Mac App Store or Microsoft AutoUpdate. After updating, the option should become active.
Issue 2: Outlook Crashes After Switching
Sometimes Outlook may crash when reverting to the old interface. This is usually due to corrupted preferences or add-ins. Try resetting Outlook preferences by deleting the com.microsoft.Outlook.plist file from ~/Library/Preferences. Restart Outlook and try again.
Issue 3: Missing Emails Or Data
Switching interfaces does not delete any data. If you see missing emails, it is likely a display issue. Go to View > Folder List and check if all folders are visible. You may need to rebuild the database using the Outlook Database Utility.
Issue 4: The New Outlook Keeps Re-enabling
If the new Outlook turns back on after restarting, there may be a conflict with your Office 365 account settings. Sign out of your account in Outlook, restart the app, and sign back in. Then switch to the old interface again.
How To Keep The Old Outlook Permanently
Once you switch, Outlook will remember your preference. However, updates or account changes can sometimes revert to the new interface. To prevent this, follow these tips.
- Disable Automatic Updates: Go to Help > Check for Updates and turn off automatic updates. This stops Microsoft from pushing changes that may affect your interface.
- Backup Your Preferences: Copy the com.microsoft.Outlook.plist file to a safe location. If the setting resets, you can restore this file.
- Use A Local Account: If you use Outlook with a Microsoft 365 account, the server settings may override your local preferences. Try configuring Outlook with a local identity instead.
- Monitor For Updates: Check release notes before updating Outlook. Some updates may remove the option to switch entirely. If that happens, you may need to downgrade.
Microsoft has stated that the new Outlook will eventually become the only option. For now, the toggle remains available, but it may disappear in future versions. Backing up your settings ensures you can restore the old look if needed.
Alternative Methods To Restore Classic Look
If the toggle does not work or is missing, there are other ways to get the old Outlook feel. These methods are not official but can help in a pinch.
Method 1: Use Outlook 2016
If you have a license for Office 2016, you can install that version instead of the newer one. Outlook 2016 uses the classic interface by default. Download it from your Microsoft account or use a previous installer.
Method 2: Modify The Plist File
Advanced users can edit the Outlook plist file directly. Open Terminal and type: defaults write com.microsoft.Outlook NewOutlookEnabled -bool false. Restart Outlook to apply the change. This forces the old interface even if the toggle is missing.
Method 3: Use A Third-Party Tool
Some developers offer tools that modify Outlook’s appearance. Be cautious with these as they may violate Microsoft’s terms of service. Only use trusted sources and backup your data first.
Method 4: Downgrade Outlook
If you recently updated and lost the old interface, you can downgrade to a previous version. Uninstall Outlook, then download an older version from the Microsoft website. Disable automatic updates to prevent re-upgrading.
What Changes When You Switch
Switching to the old Outlook changes several aspects of the app. Here is a breakdown of what you can expect.
- Menu Bar: The classic menu bar returns with File, Edit, View, Go, Tools, Window, and Help. The new Outlook hides these menus.
- Toolbar: The toolbar shows icons for New Email, Reply, Forward, Delete, and more. You can customize it by right-clicking and selecting Customize Toolbar.
- Navigation Pane: The left sidebar shows folders in a tree view. You can expand and collapse folders easily. The new Outlook uses a flat list.
- Reading Pane: The reading pane remains available but with classic styling. You can choose to show it on the right, bottom, or turn it off.
- Search Bar: The search bar is at the top of the folder list. It supports advanced syntax like from:, subject:, and has:attachments.
- Calendar: The calendar view changes to a more traditional layout with day, week, and month options. The new Outlook has a simplified calendar.
Overall, the old interface feels more like a desktop application, while the new one tries to mimic a web app. If you prefer desktop-style functionality, the old Outlook is the better choice.
