I need help please to stop the new outlook from automatically installing and replacing my windows and calendar app. I have uninstalled the new Outlook 4 times today. Every time I launch the old mail and Calendar app the new outlook automatically installs without my permission. It stops me from using the old app. This is very annoying. I don't want the new app. Is there any way to stop this from happening? Your advice would be appreciated.

Kind regards

Chris

What worked for me was deleting the new Outlook's executable ("olk.exe") from "C:\Program Files\WindowsApps\Microsoft.OutlookForWindows".

Once it's gone, it can't forcibly launch anymore when you open Windows Mail.

You first need to take ownership of the "WindowsApps" folder, then after deleting/renaming the .exe, restore the ownership back to "TrustedInstaller" (to prevent any potential issue down the line).

    I totally agree with you. I detest the new outlook and I cannot afford 365! I just want my normal mail and calendar app on my PC without having to uninstall the new one every time I log on. I'm sick of it and by the sounds of it I'm one on thousands in the same boat.

    MICROSOFT YOU NEED TO DO SOMETHING ABOUT NEW OUTLOOK. We need to be able to uninstall it forever.

    Because it’s about monetizing Mail. Notice the Mail app has no adds. New Outlook has an ad at the top of your inbox. Wanna make that annoying ad that looks like a new email go away? Pay for a subscription to Outlook. I think Gates has enough money, don’t you?

    I've been poking under the hood and found this one;

    (leave new outlook installed - if you uninstall it will just keep coming back, so leave it as-is.)

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

    open 'callback' with notepad; change the last two toggles from 'true' to 'false'. close and save.

    Then lock down the 'NewOutlookMigration' folder using the same 'deny' write access as before.

    Worth a try, mine hasn't interrupted work flow since yesterday afternoon, obviosuly still get the annoying 'Try the new Outlook' button in Mail, but hit dismiss and it's gone.

    Before this, it was constantly killing Mail and opening Outlook.
