If you live in Outlook (and let’s face it, with the ever-increasing integration with other systems, it’s what Microsoft want you to do) then it makes sense to use it as your newsreader. Up to now, the only Outlook-integrated newreader I’ve been aware of is Newsgator, although it seems that their focus is more towards pushing their online services these days.
Via Visual Being I came across RSS Popper, which does much of what Newsgator does with the added bonus (if you’re that way inclined) of being freeware. It’s a relatively early beta version, so probably best not to expect absolute stability, but first impressions are encouraging – it supports all the varients of RSS, podcasting, OPML upload and download, and so on. Particularly useful is the full-page download, which means you can cache blog pages for offline reading.
This might be worth checking out if you’re a heavy Outlook user, and prefer that to an online aggregator such as Bloglines.
