YouTube URLs being blocked by Microsoft IMs? I noticed some troubles with youtube URLs for quite some time, but never tried to investigate what is wrong. This is simply ridiculous.
That reminded me of when I signed up on Zoho.com and Thinkfree.com using my live email, and they always go to the junk mail folder. I also recall reading that some people noticed that particular invite emails from competitors never make into their hotmail inboxes. Although I can't prove anything here, it is a bit strange, isn't it?
