Hi @Latorre Ara, Ricardo,

Thank you for posting your question in the Microsoft Q&A Forum.

 

Regarding your question about permanently switching back to Classic Outlook, while there's currently no definitive method to do so, I can recommend a few workarounds that may help you maintain a more consistent experience with the classic version.

 

Before you can swap between different versions of Outlook, you will need to install Outlook (classic) onto your device. If you don't already have it installed, download Outlook for Windows (classic) from the Microsoft Store.

Once you have Outlook (classic) installed, you can start using it by disabling the modern layout. The easiest way to switch to the legacy version is by clicking on the "New Outlook" toggle at the top right of the screen.

You may be prompted to complete a brief pop-up questionnaire, but it can be skipped by scrolling to the bottom of the pop-up and clicking "Skip Feedback."

Afterward, you will be able to use the previous Outlook version, allowing you to enjoy the original design and utilize features that are still missing from New Outlook.

In some cases, the "New Outlook" toggle may not be available. This often occurs if you open Outlook through the "Outlook (new)" app in Windows. You might also be unable to find the toggle when you reopen the app after an update. Restarting the Outlook app will sometimes cause the toggle to reappear, but there is a more reliable way to swap back to Outlook (classic).

If the "New Outlook" toggle does not appear, open the "Help" tab at the top of the screen, and select "Go to Classic Outlook" from the menu below.

Once you have completed these steps, you will be swapped back to Outlook (classic).

Since both versions of Outlook can run simultaneously, many users choose to uninstall the New Outlook to ensure that the Classic version remains the default and launches without triggering the New Outlook.

Furthermore, you can look into how to block new Outlook from being installed via this article: Use Classic Outlook, not New Outlook | Slipstick Systems

You can run both the classic and new versions of Outlook side by side if needed. While Microsoft may eventually phase out the classic version, it is still supported for now. If your organization enforces the use of the new Outlook in your environment, it's best to contact your IT department for assistance.

    I am at my "end" on patience. I have been trying all the instructions/options that have given me in the new Outlook, and by uninstalling Outlook, I am unable to use my classic Outlook in order to finish my 2024-2025 Income tax. If I am unable to complete this task TODAY, I will not renew my Microsoft Office in October 2026. Changes are good if the instructions are clear for one who does not wish to change. I am a senior citizen and you have just about caused me to "give up" and that isn't the way! You buys can do better. For you to advise consumers you cannot guarantee a fix is unheard of. I can not even call support as advertised.
