How to Switch Back to the Old Outlook View on Windows

To switch back to the old Outlook on Windows, turn off the New Outlook toggle near the upper-right corner of the new Outlook window, then confirm the option to return to classic Outlook if prompted. This guide covers the Windows switch first, plus the equivalent option on Mac. The change returns you to the classic Outlook app; it does not simply restore an older layout within new Outlook.

What You’ll Need

A Windows PC or Mac with classic Outlook installed. Depending on how Outlook was set up, it may appear as Outlook (classic) in the Windows Start menu.
Permission to use classic Outlook. A work or school administrator may control which Outlook app is available.
A few minutes to switch apps and check that your account and expected mail folders appear in classic Outlook.

Your messages are generally stored in your mail account, not just in the app, so switching Outlook versions does not normally delete them. Still, do not uninstall either app or remove your account as part of this process. If you rely on local-only folders, archives, or add-ins, check that those are available in classic Outlook before relying on the switch.

Step-by-Step

Check which Outlook you have open. In new Outlook for Windows, look for a New Outlook switch near the upper-right corner of the window. If you see it, you are in the app that can offer a direct route back to classic Outlook. The exact placement can vary with window size and app updates. If the switch is not visible, check the troubleshooting section rather than changing unrelated display settings.
Save any work in progress. Send or save draft messages, finish editing calendar items, and let any uploads or attachment downloads complete. Most account data will sync, but unsent drafts and changes that have not finished syncing are worth checking before you switch. If you are working offline, reconnect to the internet and allow Outlook to synchronize first.
Turn off the New Outlook switch. Click the New Outlook toggle. In some releases, Outlook asks why you are switching or displays a short feedback panel. Choose the option to return to classic Outlook, or continue through the prompt. Avoid choosing an option that only closes the window if the prompt offers a separate return-to-classic choice.
Let classic Outlook open. The app may close or restart, and a browser page or feedback prompt may appear. Follow the on-screen instructions and give the app time to launch. If classic Outlook opens, sign in to the account you use and allow its folders and messages to load. Do not assume a blank folder means messages were erased; first check the account and folder list.
If no classic window opens, launch it from Windows. Open the Start menu and type Outlook. Look for Outlook (classic) in the results and open it. If both versions appear, select the classic entry rather than the newer Outlook app. You can right-click the classic app in the results and pin it to Start or the taskbar for easier access, if those options are available.
Confirm that you are in classic Outlook. The classic Windows app commonly has the traditional desktop ribbon and may have a different icon or app label from new Outlook. Check the title bar and the app name in the Start menu if you are unsure. A different ribbon arrangement inside the same app is not, by itself, proof that you changed versions.
Check your account and key features. Confirm that the expected email address appears, then inspect Inbox, Sent Items, Calendar, and any important archive or shared mailbox. Test a non-urgent feature you depend on, such as a COM add-in, a custom rule, or a locally stored archive. Some settings and features do not behave identically between new and classic Outlook, so verify essential workflows before closing the newer app for good.

On a Mac: Open Outlook and look for the New Outlook switch in the Outlook window. Turn it off and confirm that you want to return to the legacy version if asked. Outlook may restart. If the switch is missing, check the Outlook menu and the app’s available update or account options; the exact controls depend on the Outlook for Mac release and how it was installed. You need the legacy Outlook for Mac app or version to be available for the switch to work.

Common Mistakes

Confusing the app with its layout: “Old Outlook” usually means classic Outlook, a separate desktop app from new Outlook. Changing the ribbon, reading pane, or message list settings inside new Outlook does not turn it into classic Outlook. Use the app toggle or launch the classic app explicitly.

Looking for the toggle in the wrong place: The switch is associated with new Outlook, not necessarily classic Outlook. If you have already opened the classic app, you may not see a control that takes you back. To reopen new Outlook, search for it in Start or use the switch in classic Outlook if your installation displays one.

Assuming the change removes mail: Switching apps is not the same as deleting an account. However, a message stored only in a local data file, or a change made while offline, may not be available in the other app. Check local archives and synchronization status instead of removing or recreating the account as a first response.

Uninstalling the new app too soon: Keeping both versions available makes it easier to compare settings and return if needed. Do not uninstall an app just because you have switched back. First confirm that classic Outlook has the account, folders, and tools you need.

Expecting every preference to transfer: New and classic Outlook have different settings and feature sets. A preference changed in one app may need to be set again in the other. Check important signatures, notifications, rules, calendar options, and add-ins individually.

Tips

Use the Start menu search to distinguish the apps rather than relying on a taskbar icon you may have pinned earlier. If you are unsure which icon is which, right-click it and choose the option to open the file location or inspect its name where available. Pin the classic app only after you have confirmed it launches the version you want.

Before switching, note any custom setup that would be inconvenient to recreate: shared mailboxes, special folder arrangements, signatures, rules, and add-ins. This is especially useful for a work account managed by an organization. A short checklist lets you compare the two apps without assuming that a setting has disappeared permanently.

Keep new Outlook installed while you confirm that classic Outlook meets your needs. You can use one version at a time, and having both available can help if a feature you need is present in only one of them. If Outlook asks for feedback during the switch, answering is optional unless your organization requires a response; it does not replace the actual confirmation to return to classic Outlook.

If you use Microsoft 365 at work, ask your IT administrator before changing app versions when Outlook is centrally managed. Administrators can restrict the toggle, control deployments, or provide a specific classic Outlook installation. Their instructions take precedence over general steps because the available controls can differ by organization and license.

Troubleshooting

The New Outlook switch is missing. Make sure you are actually in new Outlook, maximize the window, and check the upper-right area again. If it remains absent, search Start for Outlook (classic). The switch may be hidden or unavailable because of the installed version, account, update channel, or an organization policy. Check for app updates through your normal Microsoft 365 update method, or ask your administrator whether classic Outlook is enabled. Do not try to change registry settings to reveal it.

Outlook switches off but classic Outlook does not start. Search for Outlook (classic) from Start and open it directly. If it is not listed, it may not be installed or available on that device. Use your organization’s software portal or the Microsoft 365 installation options provided for your account to see whether it can be installed. If the app is listed but fails to open, restart Windows and try again; contact your administrator or Microsoft support if the problem continues.

The classic app opens but asks you to sign in again. Sign in with the same work, school, or personal account you used in new Outlook. Follow any multi-factor authentication prompt. If the account is managed, a sign-in or device policy may need attention from your organization. Avoid repeatedly removing and adding the account, since that can create extra setup work and may affect locally stored data.

Your messages or folders seem missing. Confirm the email address in the account list and allow time for synchronization. Check other folders, the folder list, and any archive or shared mailbox you normally use. If you previously used a local data file, it may need to be opened or connected in classic Outlook; a local archive is different from a server-synced mailbox. If mail is missing from webmail as well, contact the email provider or IT support before making further changes.

The toggle is unavailable on a managed device. Your organization may have removed the option or may not provide classic Outlook for your account. Ask IT whether classic Outlook is installed and supported, and request the approved way to switch. Do not install an unofficial copy or use a personal account to bypass workplace settings.

On Mac, switching does not show a legacy app. Check whether the legacy Outlook for Mac version is installed and supported on your device. The switch cannot open an app that is not present. Update Outlook using the method supplied with your installation, then consult your organization’s support team or Microsoft’s current Outlook for Mac guidance if the control remains unavailable.

Frequently Asked Questions

Is classic Outlook the same as the old Outlook view?
Usually, yes: people use “old Outlook” to mean classic Outlook for Windows or legacy Outlook for Mac. If you only want an older-looking ribbon or message layout, that is a separate display-setting question and does not change the app.

Will switching back delete my email?
Normally, no. Mail in a synced account remains on the mail service. Check unsynced drafts and local-only archives separately, because they may not be stored in the same place as server mail.

Can I switch back to new Outlook later?
Often, yes. If your version provides the New Outlook switch in classic Outlook, turn it on and follow the prompts. You can also open new Outlook from Start if it is installed. An organization may restrict switching.

Why do I have two Outlook apps in the Start menu?
New Outlook and classic Outlook can be installed side by side. Their names or icons may be similar, so choose the entry labeled Outlook (classic) when you want the traditional desktop app.

Will my signatures, rules, and add-ins transfer?
Not every preference or feature transfers automatically. Check each item in classic Outlook, especially add-ins, local archives, custom rules, and signatures. Availability can depend on account type and Outlook version.

What if my company will not let me switch?
Ask your IT administrator whether classic Outlook is supported for your account and device. If the option is controlled by policy, only the organization can change that setting or provide an approved installation.
