When I worked at IBM in ‘98 Lotus Notes was the default email client for all employees - we referred to it internally as “Bloatus Goats” such was the disdain we had for it.

I am not sure triggering a mass trauma by reviving Notes is worthwhile either.

It would be hard to recreate the experience since it relied on a network to get the full experience. Instead of Notes maybe give Multiplan a go. Horrible Microsoft also-ran of a product but interesting to reminisce about.
