I think spotting, for example lookout outlook plugin acquired by MS, which seems clearly to me MS needed such solution and lookout already solved it nicely. So why re-invent the wheel and spend more money when you got a safe choice.

They didn't integrate into the Outlook though, they did integrate into Windows Desktop Search

Outlook search is powered by Windows Desktop Search I think.
