I am trying to get a user's email address in AD without success.

String account = userAccount.Replace(@"Domain\", "");
DirectoryEntry entry = new DirectoryEntry();

try {
    DirectorySearcher search = new DirectorySearcher(entry);

    search.PropertiesToLoad.Add("mail");  // e-mail addressead

    SearchResult result = search.FindOne();
    if (result != null) {
        return result.Properties["mail"][0].ToString();
    } else {
        return "Unknown User";
    }
} catch (Exception ex) {
    return ex.Message;
}

Can anyone see the issue or point in the right direction?
