Used to use Outlook Express until Micros**t canned it, went to Thunderbird but then back to Outlook, nothing wrong with Thunderbird but Outlook seemed more like I was used to but still preferred what was Outlook Express, can't be specific now, too long ago, but it wasn't broke so why did they fix it ? The Outlook Spam filter seems OK, and you can arrange "folders" to try to organise e-mails that you want to categorise.
