It did its thing—internet email—really well. It was aimed squarely at the user with like a POP account, and it had a clean UI and plenty of features. For the time and use case, it was a fantastic client.

Outhouse tried to be too many things at once. Email client with HTML/rich text features that made it leave Microsoft crufties including mso: tags and the infamous J smiley all over your emails, contact manager, calendar. It was heavyweight, slow, and not quite there in terms of UI. But if you're an MBA type and you're committed to MSFT, or you're looking for a turnkey solution and it's this or Lotus Notes, Outhouse and Exchange sound like a win.
