I am interested to ask if i have a website and some pages have been removed from the website, and those pages are still indexed in msn then how will i get those pages deindexed in msn... ??
If you were remove that pages from your site then MSN will also remove from his SERPS you need to wait and one think you can do remove that pages from your server also.
Have you setup your robots.txt to block MSNbot ? If yes then just wait for a bit and it will deindex the pages The robots.txt should look like this User-agent: MSNbot Disallow: / (or specify the pages)
