Einar,

I don't use Outlook, so I can't actually look at an example of what you're talking about, but it sounds more like TreeView behavior than ListView. But, I just found, via Intellisense, something called ListViewGroups. So I went into the docs and found that it is something new to .NET 2.0 ... first I've heard of it, but I bet this is what you're looking for. If I have any free time this weekend, I might play with it and see.
