Outlook now ignores Windows' Default Browser and opens links in Edge by default

This is stark evidence that the fines are coporations are way to low. Wasn't the eu microsoft ones record setting before and here they are asking for a new one.

There's a GPO to turn it off, but you'll need to download the latest Office GPO package. Here's a PowerShell script if you're running an RMM tool - it'll need to run as user:

Function SetRegistryKey($RegistryPath, $Name, $PropertyType, $Value){
    # Create the key if it does not exist
    If (-NOT (Test-Path $RegistryPath)) {
      New-Item -Path $RegistryPath -Force | Out-Null
    }  
    # Now set the value
    New-ItemProperty -Path $RegistryPath -Name $Name -Value $Value -PropertyType $PropertyType -Force
}

SetRegistryKey "HKCU:\Software\Policies\Microsoft\office\16.0\common\links" "BrowserChoice" DWORD "0"
