I was flummoxed when my wife, who has a standalone Office license because she works for a tiny startup, was having trouble with an Excel formula. I asked her to click on the tooltip for the formula Help box to figure out what was wrong with the syntax, and the help screen said "This Version is No Longer in Support" which, while true, was infuriating because there's no reason that the Excel function help index needs to be live content rather than a KB of text in the installer. Their business side support will likely continue (in the US at least) for some time because of the cost and complexity of replacing it all but every choice to lock in that market gets more and more hostile to smalltime users.
