Conversion of New Outlook to Classic Outlook

Question

How do I restore and convert the new 365 outlook e-mail to classic e-mail?

Answer 1

If you have a license which includes the classic Outlook (Microsoft 365 Personal, Microsoft Office Home & Business 2024, among others), see https://support.microsoft.com/en-us/office/install-or-reinstall-classic-outlook-on-a-windows-pc-5c94902b-31a5-4274-abb0-b07f4661edf5 .

Answer 2

To restore and convert from the new Outlook to the classic Outlook, you can use the toggle switch available in the new Outlook interface. This toggle is typically located at the top right of the new Outlook window. If you don't see the toggle, it may be due to certain restrictions or settings in your environment.

If you are unable to access the toggle, check the following:

1. Ensure you are using a supported Windows version (Windows 10, Build 1809 or higher).
2. Confirm that you are on a supported channel (Current Channel, Monthly Enterprise Channel, or Semi-Annual Enterprise Channel (preview)).
3. Verify that your Outlook profile does not contain unsupported account types (e.g., POP or on-premises Exchange accounts).
4. If the toggle is hidden due to registry settings, you can change the HideNewOutlookToggle registry key to 0 to make it visible again.

Once you have access to the toggle, simply click it to switch back to classic Outlook. If you encounter any issues, consider reaching out to Microsoft Support for further assistance.
