How to uninstall Outlook (new) on Windows 11 and prevent it from redownloading when opening the Windows Mail?

Dear Aetherum,

Thanks for using Microsoft products and posting in the community.

I understand that you want to return to the classic Outlook. Thank you for your efforts and attempts, and now I will do my best to help you solve this problem together.

Here are some methods you can try:

Method 1. Delete, C: \ Users \ [Your Computer Username] \ AppData \ Local \ Packages \ microsoft. windows communications apps_8wekyb3d8bbwe \ LocalState \ Migration \ settings. json

After deleting the settings. json file, change the security write permission of the folder Migration to deny.

Remember to select the current Windows user name. Please cautious operation.

Method 2. To revert New Outlook to the old version, you can use the toggle switch in New Outlook. If the toggle switch does not display, you can refer to this link. Toggle out of the new Outlook for Windows preview - Microsoft Support

Method 3. You can also rollback by uninstalling New Outlook. Search for Settings - Apps in the search bar below your computer, find Outlook (New) in the installed apps, and click the three dots on the right to uninstall it. After uninstalling, you may encounter Mail crashes, but after reopening Mail multiple times, it can be opened normally.

Hope this help you, please feel free to let me know how it goes. If there is any deviation in my understanding, please forgive me and provide me with more details. I am more than happy to continue to help you.

Hello!

Many thanks for your support!

I tried the methods you suggested, but I still can not uninstall Outlook (new), as it auto-installs after I use the Mail app a couple of times.

Regarding the methods you suggested:

• I tried method one and then method 3, but after opening the Windows mail app a couple of times, it auto-installs Outlook (new) again and redirects me there.
• I also opened the link in Method 2, but I cannot find the Preferences folder inside the registry path of Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences. What I have is just two lines (Default) - (no value) and Bitness - x86.

Hello,

I wrote on 19 octobre:

I found out the new Outlook version is in the following folder:

C:\Program Files\WindowsApps\Microsoft.OutlookForWindows_1.2024.925.0_x64__8wekyb3d8bbwe.I prevented the installation of the new Outlook bij renaming of the folder Microsoft.OutlookForWindows_1.2024.925.0_x64__8wekyb3d8bbwe.To do this I had to become owner of the ( Hidden) folder C:\Program Files\WindowsApps.How to change owner is written here:https://www.guidingtech.com/how-to-access-windowsapps-folder-on-windows/

The slider remains.

Thats still valid, only the folder of new outlook has another name after the latest update.

I renamed both files:

Microsoft.OutlookForWindows_1.2024.1023.300_x64__8wekyb3d8bbwe

and Microsoft.OutlookForWindows_2.2024.925.0_x64__8wekyb3d8bbwe

Why isn't MS adding to the conversation, and helping? They are silent. How do we stop Outlook New from constantly and repeatedly installing? I have uninstalled it every time it installs. Sometimes multiple times a day. As fast as I uninstall it, it reinstalls itself. Outlook New is awful. It is not ready for prime time. Why is MS forcing this on us, and constantly installing it, as fast as we uninstall it? Has NS not gotten the idea that we do not want it? It really screws things up, especially at sites with multiple computers on a network. Is there not a way to STOP Outlook New from repeatedly installing?
