My territory was mainly scandanavian countries, due to a go getter salesman in that region, so I got to see that part of the world on expenses and do really interesting tech. What a time.
The fun thing about that statement is I have no idea whether it was sarcastic or heartfelt. I have never found a more polarizing piece of software in my long career. It’s a love or hate there and doesn’t seem to be any “meh” opinion. (I was in the hate camp and thankfully my life has been Notes free for over 15 years)
After working in it for a while I’d start to notice the Notes email and calendar are just specialized notes applications. It’s not the best..
Basically it was a server for Lotus Notes solutions. You could flick a switch, and then you turned your Notes-based solutions into web-applications.
It seems it still exists in some form: https://www.theregister.com/2021/06/08/hcl_domino_12_debuts/
But possibly MVS customers outnumbered VM/CMS ones to the point that you rarely or never worked with any of the later
Main reason for switching was that it was going to pay for itself, as Notes was expensive. But we also had hundreds of applications in Notes with no replacement plan or budget to do so, so they barely got rid of any licenses.
