Can I see what categories an RSS post has using the object model or the UI?

It would be quite usefull to create Search folders or views based on categories from all subscribed RSS feeds.

I dont think the categories from the feed is stored in the Categories property of the Outlook.PostItem. Am I missing something or is there another way of getting the feed categories?

Ah, you mean the categories that popular blog software assigns to items? Outlook rightly does not promote the <category> element in the original feed item XML, because the author's category structure might be at odds with the Outlook user's preferred category structure.

However, Outlook does store the complete XML for the item in a named property {00062041-0000-0000-C000-000000000046}. If it's small enough, you can get it with PropertyAccessor. However, we've seen problems with out-of-memory errors in B2TR with PropertyAccessor text properties as small as 14k, so it's not clear what "small enough" is going to mean.

Thank's again Sue!

Do you know where the feed URL is stored? If I know the feed for the item or items folder and the unique id of the feed item, then I could fetch the categories from the original feed.

It would be quite nice to create an UI that could map feed categories to my Outlook categories with a many-to-one relation. That way I could all known variants to map to a single category.

ps. Is there anything you don't know about Outlook?

Re: the feed URL, see my reply to your post at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=811322&SiteID=1.

There's a lot I don't know about Outlook, but with the help of Outlook Spy, the other MVPs, and some great folks at Microsoft, we can figure out quite a bit.

What is Outlook Spy? Sounds like good tool. Is available for public download?
