I wanted to disable the prompt and button for new Outlook. I found this guide and wrote a few lines of PowerShell to automate it and wanted to share.

# Source https://edi.wang/post/2025/1/20/how-to-stop-automatically-switching-to-new-outlook
$path='HKCU:\Software\Microsoft\Office\16.0\Outlook'

# Remove and create to ensure correct data type
Remove-ItemProperty -Path "$path\Options\General" -Name 'NewOutlookAutoMigrationStage' -ErrorAction SilentlyContinue
New-ItemProperty -Path "$path\Options\General" -Name 'NewOutlookAutoMigrationStage' -Type DWord -Value 1
Remove-ItemProperty -Path "$path\Options\General" -Name 'NewOutlookAutoMigrationStage'
Remove-ItemProperty -Path "$path\Options\General" -Name 'NewOutlookAutoMigrationType'
Remove-Item -Path "$path\NewOutlook"
# Remove and create to ensure correct data type
Remove-ItemProperty -Path "$path\Preferences" -Name 'UseNewOutlook' -ErrorAction SilentlyContinue
New-ItemProperty -Path "$path\Preferences" -Name 'UseNewOutlook' -Type DWord -Value 0
Remove-ItemProperty -Path "$path\Preferences" -Name 'NewOutlookRenudgeStartDate'
Remove-ItemProperty -Path "$path\Preferences" -Name 'NewOutlookRenudgeStartDate'

    Does this work different than the policy key? As far as I know the keys under software\policies are used by both group policy and intune, and honored by windows home editions so I’d expect they’d work more reliably than an outlook config setting.
