    Get-MailContact | Set-MailContact -EmailAddressPolicyEnabled: $false
    $MailContacts = Get-MailContact
    $MailContacts | foreach {$contact = $_; $email = $contact.emailaddresses;
    $email | foreach {if ($_.smtpaddress -like “*@contoso*”) {$address = $_.smtpaddress;
    write-host “Removing address” $address “from Contact” $contact.name;
    Set-Mailcontact -Identity $contact.identity -EmailAddresses @{Remove=$address}}}}
