How to switch from outlook classic to New Outlook, Using windows 11 version 2024

On Windows 11, first search Start for Outlook and open the entry without “(classic)”; if it is not installed, use the Try the new Outlook toggle in classic Outlook or install the app from Microsoft Store.

Switch to new Outlook

1. Select Start and type Outlook.
2. If two results appear:
   • Outlook — new Outlook
   • Outlook (classic) — classic Outlook
     Open Outlook. You can right-click both entries and select Pin to taskbar to keep them available side by side.^1^
3. If only classic Outlook appears, open it and look in the upper-right corner for Try the new Outlook.
4. Turn on the toggle, wait for the download, and select Switch.
5. Follow the prompts to sign in. Select Import Settings if you want to copy supported settings from classic Outlook.^2^

If the toggle is missing, that can occur with a non-subscription Office edition such as Office Home & Business, an unsupported account, or an administrator-controlled installation. Install new Outlook separately:

1. Open Microsoft Store from Start.
2. Search for Outlook for Windows.
3. Select Get, then Open.
4. Sign in with the email address and password supplied by your internet provider.^3^

Will switching fix synchronization?

It might, but it is not guaranteed. New Outlook supports third-party accounts connected through IMAP and POP, so an internet-provider account can generally be added.^4^ However, switching applications does not correct an invalid password, incorrect incoming/outgoing server settings, or a provider-side mailbox problem.

After opening new Outlook:

1. Select Settings (gear icon) → Accounts → Email accounts.
2. Add the provider account if it was not imported automatically.
3. Send yourself a test message and check whether it appears in both:
   • New Outlook
   • Your provider’s webmail page

If messages appear in webmail but not in new Outlook, remove and re-add the account under Settings → Accounts → Email accounts, then restart Outlook. This refreshes the app’s local synchronization data.^5^

Keep classic Outlook installed until sending, receiving, folders, and contacts work correctly in the new app. You can run both versions side by side, but avoid making organizational changes in both during testing.
