How To Stop The New Outlook From Automatically Installing

This does work!

Just 2 steps.

1. C:\Users[Your computer's username]\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Migration\settings.json

You just need to delete the settings.json file, and you will be able to open Mail directly.

2. then add this additional step

Users/(you)/AppData/Local/Microsoft/Outlook/NewOutlookMigration/

Then lock down the 'Migration' folder as follows:

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

Right-click on the Migration folder, go to Properties, and under the Security tab.

Click Edit, select the current Windows name, check the Write permission as Deny, and apply.

However.. while this is a working solution, I have completely lost all respect and faith in microsoft and have decided instead to switch my email server to Mailbird.

Microsoft doesn't give a cr@p about what any of us want and complaining here wont be heard by anyone that really matters at MS.

That's why I can tell you my work around and not fear that MS will shut it down. But if they do, then we'll know they're listening but they just don't give a f&^k.

Once you get the Mail app up by deleting Outlook (new) then quickly opening Mail, leave it running. Do not close it. Outlook (new) will reinstall but it will not replace Mail if it's left open. Don't turn off your computer either, just put it to sleep.

Thanks MS. You su8k!

Agree with your thoughts about MS. I delete the outlook and get my old mail back. My problem is MS is trying to force me to use outlook and my computer is windows 10. Outlook will not run on it. I get notice to update my software only to be told Windows 11 won't run on the computer. I don't want to load ANYTHING to their cloud. The government spies on us too much already. MS forces you to use the cloud. What is this cloud. The new NSA spy tool? MS could stop this if they wanted. They don't care about the customers. If I could find something else to us I'd drop MS in a second. What an arrogant company

Hello Jimmy, I tried this and denied write access for my current user. I previously uninstalled the new outlook and deleted the .json files. However Outlook automatically installed anyway.

Then I tried denying all except full control and modify. Outlook still installs automatically.

I suspect this fix no longer works. If there is anything else I can try, please let me know,

I need the old mail app because it has the protocol that enables me to use a specific microsoft exchange account. The new outlook does not have the correct protocol and cannot access this Microsoft exchange account. The new outlook is of no use to me.

Thanks again for your help

Kind regards

Chris

Hi Chris,

Welcome to the Microsoft Community.

I understand the distress this causes. Please try deleting the following file to end the jump.

C:\Users[Your computer's username]\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Migration\settings.json

You just need to delete the settings.json file, and you will be able to open Mail directly.

I hope this works. If you encounter any issues, please contact me again.
