Using Classic Outlook on Windows for personal email, calendar, and contact management
Those are similar but not the same as what I was given. I only had the one key, not the WoW6432Node one, and it was enough for me. I would say that is unlikely to be a permanent fix, also. There's some change that MS is pushing out - this key allows you to opt out of the change temporarily, I guess, but once the experiment becomes production code, the "Override" won't work anymore I bet. That's why you should open a ticket and get the key - the more MS knows this is an issue, the better. I'm not trying to be difficult here - I explicitly asked if I can distribute the key and they told me no, so I'm trying to honor that while I'm working with them.
