Lotus Notes was astounding when it arrived.

Windows had barely landed. Networking was really only used for file serving in most corporations. There was no email at most companies and TCP/IP was still mostly a university and government thing.

Notes turned up as a deeply sophisticated Windows application, a no-code development environment, document oriented, replicated distributed shared data system with built in security encryption, email and all deeply integrated with the concepts of people and groups of people, which everyone takes for granted now, but back then wasn’t part of corporate computing at all.

The email alone led the rise of Lotus Notes, let alone the rest of the system.

Using Notes you could suddenly create applications that shared data across your office locations - you ran a server locally and Notes dialed up the other servers and did replication of just the changed/different data. It was gob smacking because nothing else could do this.

At a time when personal computing was very much the model, it was like someone had sent this software from the future.

I did contract work for a company who made heavy investments into Notes-based applications. The replication capability was super cool. We would setup a new client computer on the corporate LAN, synchronize them to the various Notes databases they needed, then send the computer out to field service reps who would use the computers mostly offline. They updated over a pool of dial-up modems at headquarters. They would run mostly overnight, with the field service reps dialing-in before bed and leaving it to run until it automatically disconnected. Later they used a VPN and dial-up ISPs. It worked astoundingly well.

Their developers moved thru the organization over a period of years making Notes databases out of every paper form-based workflow process they could get their hands on. I lost touch with them and they were acquired by another company, ultimately. I'd love to know what happened to all those custom applications living in Notes. It's hard to think of a platform that could have easily replaced it-- particularly the offline sync / local first portion.
