Remove special characters from email attribute

Question

Hi,
I found the following example to remove special characters from an attribute but somehow I can't get it to work.
I'm using this script in a business rule before creating the user.

$props = @("email","sAMAccountName", "userPrincipalName")
$map =@{ "å"="a"; "ö"="o"; "ä"="a";"ü"="u"; "ñ"="n"; "é"="e"; "-"=""; "'"="" }

foreach ($prop in $props)
{
    if ($Context.IsPropertyModified($prop))
    {
        $value = $Context.GetModifiedPropertyValue($prop)

        foreach ($key in $map.Keys)
        {
            $value = $value.Replace($key, $map[$key])
        }

        $Context.SetModifiedPropertyValue($prop, $value)
        $Context.LogMessage($prop + ": " + $value, "Information")
    }
}

Can someone identify what i'm doing wrong?
Incorrect if statement?

Comments

My apologies, "sAMAccountName", "userPrincipalName are actually being done.
Email was not set correctly, I used "Email" where it had to be "mail"

Changed it and now it work, THX for the support!!
